Unit 5 Anatomy and physiology Functions of the component of the human cell.(
Cell membrane: the cell membrane also known as plasma membrane is the biological membrane that separates the interior cell from the outside environment. It provide support and protection for the cell. It serves as the entrance and exit of the cell.
Cytoplasm: cytoplasm is a jelly like material that fill the cell. It contains food and water for the cell. It holds the organelle in place. It is mainly composed of water, salt and proteins.
Nucleus : it contains the majority of genetic materials as DNA molecules along with variety of protein to form chromosomes. which makes humans who and what they are.
Endoplasmic reticulum: the endoplasmic reticulum serves many functions, it folds protein molecules in sacs cisternae, it transports synthesized proteins in the vesicles to the Golgi apparatus.
Golgi apparatus: it is made up of membrane bound sacs .The function of the Golgi apparatus is to process and bundle macromolecules like protein and lipids as they synthesize in the cell. It modifies sorts and package proteins to be secreted.
Mitochondria: it is of the referred to as the powerhouse . It breaks down food and release energy to the cell.
Lysosomes: they organelle that contain the digestive enzymes. It cleans up the cell’s waste product.
Centriole: the main function of the centriole is to help the division in cells. It also helps in the formation of the spindle fibre s that separate the chromosomes during cell division. Chromatin: the main function of the chromatin is to efficiently package DNA into small volume to fit into the nucleus of the cell and protect the DNA structure and sequence. Chromatin also allows for mitosis and meiosis prevent chromosome breakage and control s gene expression and DNA replication.
Ribosome: it can be found floating in the cytoplasm or attached to the endoplasmic reticulum. It repairs damage and direct chemical processes.
Vacuole: it is storage bubbles found in the cell. They are found in both plant and animal cells. It surrounded by a membrane and It holds materials and waste products.

P2 The main tissues of the body
Tissues are a group of similar cells performing a specific functions.(Atkinson 2015) There are basically four types of tissues in the human body namely, Epithelia, connective, muscular and nervous tissues. Each of these tissues has it’s functions.
Epithelia tissue covers the whole body surface and form the lining for the internal cavities. It is made up cells closely parked and arranged in one or more layers. Epithelia tissue can be divided into two groups depending on the number of layers it compose of. The two types epithelia tissues are, simple epithelium and stratified epithelium Simple Epithelia:
Simple epithelia
This has one thick layer and can be divided according to the functions of the cells as follows
Cuboidal epithelium: these are called cuboidal because it has shape of cuboids and are found in glands ducts and kidney tubules lining. They also play roles in the production of egg cells in female ovary and sperm cells in males.
Columnar epithelium: these are shaped like columns and found in one or more layers. They form the lining of the stomach and intestines. Some are also involved with sensory organs such as tongue (taste buds) ears and nose.
Squamous epithelium: these are thin and flat in appearance and are responsible for the lining of mouth cavity, heart, lungs and blood vessels. They also make the outer layer of the skin.
Compound or Stratified Epithelia
These Epithelia are made up of several layers of cells and this is in order to withstand wear and tear of the body lining. Compound Epithelia can be keratinised or non keratinised. found Keratinised Stratified Epithelium: these are dry and contain a high resistant protein called keratin. These are be in mammal skins, hair and nails and it serves as protection to the body.
Non Keratinised Stratified Epithelium: these are wet and does not contain keratin. They can be found in the lining of the mouth cavity, oesophagus and during eyes lubrication.
. Epithelia tissue is the first to differentiate the embryo. It is found in the duct and the glands. Epithelia line between most organs such as the stomach and the intestines, the kidney and pancreas. It also lines the oesophagus. The image below shows the structure of epithelia tissues. The functions of epithelia tissue are as follows.
Protection: epithelia tissue protects the underlining tissues from mechanical injure, harmful injure. It invade bacteria and excessive loss water.
Sensation: sensory stimuli penetrate specialise epithelia tissues containing sensory nerves ending is found in the skin, eyes ,ears, nose and the tongue
Secretion: epithelia in the glands is specialised to secrete specific chemical substances such as the enzymes, hormones and lubrication fluids.
Excretion :epithelia tissue in the kidney excrete waste product from the body and reabsorb needed materials from the from the urine. Sweat is also excreted from the body by epithelia cell in the sweat glands.
Absorption: epithelia cells in the small intestine absorb nutrients from digestion of food.
Diffusion: simple epithelium promotes the diffusion of gases , liquid and they form lining , they are ideal for the diffusion of gases. Example wall, capillaries and the lunge.
Cleaning : ciliated epithelium assist in the removing dust particles and foreign bodies which have entered the air passage.
Connective tissues: they are most widely distributed inbody and lie under the the epethelial tissues. They connec different part of the internal structure. The main functions of the connective tissues are: the cartilage bind and support other tissues in the body. Connective tissues allow the passage for nerves and blood vessels through other tissues. Connective tissues also tansport nutients and metabolic byproducts btween the bloodstream and the othe tissues. Cnnective tissues are made up of proteins like collagen , elastin and intercellular fluids. Connective tissue basdically binds together all types of tissues. IT also reponsible foer secretion of intercellular ground sustances known as the matix. The matix maybe liquid such as blood.

The nervous tissue:( ttps:// The nervous tissue is responsible for sensing stimuli and transmitting signals to and from different part of the parts of an organism. The basic unit of the nervous system is the neurons. The nervous tissue brings about a response to the stimulus as in the brain, spinal cord and epithelia nerve. The stimuli are integrated to provide co-ordinated response in various organs. The sensory neuron helps nerve impulse from the sense organs to the central nervous system.
The muscular tissue Muscular tissue are divided into three main groups according to their structure. These are smooth muscles, skeletal muscles and cardiac muscles tissues. The functions of the muscular tissues are as follows
The muscular tissue allow movement in the body and it’s parts. The function of the muscular tissue muscular depends on the location of the tissue. muscular tissue stabilizes joints. It adds stability to joints that have poor reinforcement and articulates surface that do not fit well, such as in the shoulder and the knee joints. It also helps to maintain posture and contracts adjustments almost to continuously to the body in stationary position such as sitting or standing. The cardiac tissue tissues enhance the contraction of the atria and the ventricles of the heart . It causes the rhythmical beating of the heart, circulating the and its content throughout the body as a sequence. The smooth muscular tissue controls slow involuntary movements such as the contraction of the muscle tissue in the wall of the stomach and the intestines.

...Throughout this assignment the anatomy and physiology of the central nervous will be examined in relation to the affects a stroke may cause. The causes and symptoms will also be identified along with the various affects a stroke may have on an individual such as physical, emotional, and social impact. Finally, the care and treatments provided will be highlighted and will be referenced throughout according to relevant literature and guidelines such as Infection control, Health and Safety, and various government policies. According to the National Stroke Strategy 2007, a stroke is a condition in which the brain cells suddenly die due to a lack of oxygen. A stroke is often caused by an obstruction in the blood flow, or the rupture of an artery that feeds the brain (reference). The two main types of stroke which will be referred to throughout the text are hemorrhagic and Ischemic. National Stroke Strategy (2007) states that ‘an Ischemic stroke accounts for around 87% of all strokes and occurs when a blood clot (thrombus) forms that blocks the blood flow to a certain part of the brain’. When a blood clot forms somewhere in the body and breaks off to become free-floating, it is called an embolus (reference). This wandering clot may then be carried through the bloodstream and to the brain where it can then cause an ischemic stroke. A hemorrhagic stroke occurs when a blood vessel on the brain's surface ruptures and then fills the space between the brain and skull with blood or when...

Anatomy and Physiology

...Summary Week 1 Discussion This discussion we looked at two examples of the heart and its functions. Atrial septal defect (ASD) is fairly common. This was a terrific example to relate structure and function. When the structure of anatomy is disrupted we can see as in this example how normal function is altered. This congenital defect allows blood to flow between atria instead of the normal flow through the ventricles and to the body and the disrupted and limited blood flow can lead to heart failure, stroke and pulmonary hypertension. The larger the hole the more quickly surgery is needed to correct it. Smaller holes may provide enough blood flow to avoid these complications and may heal over on its own. Ventricular septal defect (VSD) is less common. A hole between the ventricles allows mixing of oxygenated blood from the lungs with de-oxygenated blood returning from the body. Heart failure and infections occur rapidly due to the lack of oxygenated blood reaching the body and the baby often presents with a bluish discoloration to the skin as a result of lack of oxygen. Artificial hearts being developed run on batteries to pump the blood and include porting valves to ensure blood flow goes in the correct direction. Essential characteristics of an artificial heart that would make them ideal would be to mimic the real heart in structure and function and resist rejection in the recipient.

...Anatomy and Physiology Task 1 1. Discuss your dissection of the sheep heart and the cardiovascular system of the fetal pig by doing the following: a. Describe the similarities and differences between the fetal pig heart and the sheep heart. Differences: 1. Size 2. The left ventricular wall is thicker in the sheep than the fetal pig. Similarities: They both have 2 atria and 2 ventricles. b. Describe the four valves of the heart, including their name, location, and function. The four valves of the heart are the tricuspid valve, the pulmonic valve, the mitral valve, and the aortic valve. The tricuspid valve: It is located between the right atria and the right ventricle. It is comprised of three “flap-like cusps” which when in its closed position, prevents the deoxygenated blood entering the heart from the body, from backing up in the right atrium from the right ventricle (regurgitation). The Pulmonic Valve: This valve is found between the right ventricle and the lungs. As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood......

Reflection on Intro to Physiology/Anatomy

...We started with the introduction to anatomy by defining it as the scientific discipline that investigates the structure of the body. I have discovered that there are two basic approaches to the study of anatomy are systematic (by system) and regional (by area), the latter which is more commonly used in most medical schools. And of course studying the structure is not enough, this is where physiology comes in which is the scientific discipline that deals with the processes or functions of living things. I have known homeostasis as the maintenance of the relatively constant environment in the body but it is only now that I have learned about positive and negative feedback mechanisms which maintain homeostasis and that positive homeostasis can be detrimental at times. I’ve also learned more on the anatomical terms that will be used throughout our course and maybe even in med school. In the study of cells, I was able to recall the things we have discussed in our biological science course in the previous year. I remember the three types of solution namely hypotonic, isotonic, and hypertonic. I also come to know more about the different movements across the cell membrane. However I was new to the transcription and translation that happens in the gene expression of a cell. I was able to associate codons of the mRNA strand with the anticodon of the tRNA. Similar to cytology, I was also able to look back on our discussions about tissues last year. I have refreshed myself on......

Anatomy and Physiology of Respiratory System

...Anatomy and Physiology of Respiratory System Overview Cells in the body require oxygen to survive. Vital functions of the body are carried out as the body is continuously supplied with oxygen. Without the respiratory system exchange of gases in the alveoli will not be made possible and systemic distribution of oxygen will not be made possible. Thetransportation of oxygen in the different parts of the body is accomplished by the blood of the cardiovascular system. However, it is the respiratory system that carries in oxygen to the body and transports oxygen from the tissue cells to the blood. Thus, cardiovascular system and respiratory system works hand in hand with each other. A problem in the cardiovascular system would affect the other and vice versa. Functional Anatomy of the Respiratory System Nose The nose is the only external part of the respiratory system and is the part where the air passes through. During inhalation and exhalation, air enters the nose by passing through the external nares or nostrils. Nasal cavity is found inside the nose and is divided by a nasal septum. The receptors for the sense of smell, olfactory receptors are found in the mucosa of the slit-like superior part of the nasal cavity which is located beneath the ethmoid bone. Respiratory mucosa lines the rest of the nasal cavity and rests on a rich network of thin-walled veins that warms the air passing by. Important information about nose is the presence of the sticky mucus that is......

...Anatomy and Physiology 2, SCI 136 Research Project Number 40904000. There are many different types of Arthritis. Some of these types are caused by infections, some by injury, some by aging, and some by entirely unknown causes. Infectious arthritis may follow influenza, typhoid fever, tuberculosis, syphilis or gonorrhea. Arthritis of an unknown cause is common and Rheumatoid arthritis is the worst form. Chronic arthritis is common. It has three main forms: osteoarthritis, rheumatoid arthritis, and gout. Osteoarthritis is an inflammatory condition of one or more joints the main symptoms of arthritis are joint pain and stiffness, which typically worsen with age. This is the most common form of arthritis. This disease is known as a degenerative joint disease. It affects about 80% of all Americans. The pain is caused by the degeneration of the joint. The damage to the cartilage occurs as the disease progresses and degenerates and may form some bony spurs at the end of the bones. The bones may grind against each other. Cartilage normally serves as a shock-absorbing cushion between the bones. When it breaks down it results in bones rubbing directly against one another during movement. This friction between the bones causes the bone to thicken, and spurs develop .As time goes on; these abrasions can cause permanent joint damage. Osteoarthritis is most common in the knees, hips, hands and spine. Rheumatoid arthritis is the worst form arthritis. It is a chronic......

The Anatomy and Physiology of the Respiratory System

...the baby is usually stimulated so that it begins to cry. As soon as the baby cries for the very first time, and gasps for its first breath of air, this will actually cause the bronchiole tree to inflate. And once it inflates, subsequent breaths will continue the inflation until the baby is able to breathe on his or her own. When we age, elastic tissue will deteriorate causing lower lung compliance. Chest movements are restricted by arthritis. And some changes of emphysema naturally occurs with age. And of course smoking can increase the risk of emphysema, but emphysema is defined as a chronic, progressive condition, characterized by shortness of breath, and inability to tolerate physical exertion.

In  this assignment I will be explaining the physiology  of two named body systems in relation to energy metabolism in the body. Firstly,  I  will  start off by giving a definition of energy metabolism in the body. Metabolism in the body   is  a  collection  of  chemical  reactions  that  takes  place   in  the  body’s  cells.  Metabolism converts  the  nutrients  in  the food  that we eat in  to essential energy which is needed to power all  that  we  do,  from  something  as  little  as  thinking  to  growing  physically  or  carrying  out  a physical  activity.  In  our  body’s,  there  are  specific  proteins  which   controls  the  chemical reactions of metabolism. Secondly,  the  two  body  systems that  I  will write  about  in  relation  to  energy  metabolism  are: the cardiovascular system and the digestive system. The cardiovascular system. The  heart  is  the  vital  muscle  that  pumps  blood  around  the  body  through arteries,  capilleries and  veins.  One of the functions of the heart  is to carry around blood which contains dissolved oxygen  to  the  body cells and then banishes  any wastage of respiration. The blood in  our body also......

...She turned around to run out of the dark room he’d pushed her into, and just like that, there was a knife in her occipital. She wasn’t dead yet, just suffering. Her integumentary could still feel every cut being made on her anatomy. She was finally relieved when her nervous system shut down and her life slipped away. The Villain could see the relief in her orbitals . . . so he carved them out and put them in his pocket. Alexander Morgan woke up sweating profusely from his axillaries, along with the entire posterior of his body. His deltoids were sore and his cranial ached. When he tried to sit up, a chord attached to his pectoral held him back and he realized that there was a searing pain in that same spot. He put his dorsum to the side of his mental and realized there were tiny cuts. He looked down and saw a sagittal slit down his thoracic cavity. “Dr. Morgan, you’ve been in a coma for three days now, you were attacked.” explained the doctor. “Attacked? By who?” “The police believe it was the work of The Villain.” Suddenly, it all became clear to him. The Villain was real, and wasn’t just someone Alexander Morgan dreamed about. It seemed like déjà vu. The real Alexander Morgan was not a detective, in fact he had a doctorate degree in physiology. He decided that was why his dream was so technical.
