Systems of the Human Body

There are many systems in the human body. These systems include the circulatory system, respiratory system, immune system, skeletal system, excretory system, urinary system, muscular system, endocrine system, digestive system, nervous system and the reproductive system. I will give the basics on each system.
The circulatory system includes the heart and blood vessels. It pumps blood to the body which sends oxygen to the cells and takes away waste. The respiratory system includes the nose, trachea and lungs and is needed to deliver oxygen to the blood and also to take away carbon dioxide from the body. Then, there is the Immune system which helps to keep the body stay well and free from diseases. In the immune system, are different kinds of cells, proteins, organs and tissue like our skin which is the very first line of defense for the immune system. The skeletal system includes the bones and helps us stay upright and able to move and protects the body’s organs along with the muscular system which is made up of the muscles. The excretory system includes the lungs, large intestine and kidneys. Its job is get rid of the waste that the body makes in the form of exhaling carbon dioxide from the lungs, feces from the large intestine and urine from the kidneys. . The urinary system is made up of the bladder and kidneys and is actually part of the excretory system as it rids our bodies of waste in the form of urine. The digestive system includes the mouth, esophagus, stomach and intestines and is responsible to breaking down our food to be delivered to our body in the different areas it needs to go. The endocrine system is made up of glands and they tell your cells of your body what they need to do. The nervous system is made up of brain, spinal cord and nerves. The nervous system is like a control system for our bodies and

Human Body System

...The Digestive System is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. After the food is chewed and swallowed, it goes down the throat and enters the stomach. It is further broken down by powerful stomach acids. From the stomach the food travels into the small intestine. This is where your food is broken down into nutrients that can enter the bloodstream through tiny hair-like projections. The excess food that the body doesn't need or can't digest is turned into waste and is eliminated from the body. The digestive system is a key component of everyday life due to the fact it handles all the intake of water and food sources. The Endocrine System is made up of a group of glands that produce the body's long-distance messengers, or hormones. Hormones are chemicals that control body functions, such as metabolism, growth, and sexual development. The glands, which include the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, thymus gland, pineal body, pancreas, ovaries, and testes, release hormones directly into the bloodstream, which transports the hormones to organs and tissues throughout the body. This system is not a major component but does play an important role in the growth process. The Lymphatic System is also a defense system for the body. It filters out organisms that cause disease, produces white blood cells, and generates disease-fighting...

...Introduction A system is made up of different tissues and organs working together to perform a specific function in the body. Skeletal system: Skeletal system is the system of bones, associated cartilages and joints of human body. Together these structures form the human skeleton. Skeleton can be defined as the hard framework of human body around which the entire body is built. Almost all the hard parts of human body are components of human skeletal system. Joints are very important because they make the hard and rigid skeleton allow different types of movements at different locations. If the skeleton were without joints, no movement would have taken place and the significance of human body no more than a stone. Components of Human Skeleton Human skeleton is composed of three main components; Bones, Associated cartilages and Joints. Bones: Bone is a tough and rigid form of connective tissue. It is the weight bearing organ of human body and it is responsible for almost all strength of human skeleton. Cartilages: Cartilage is also a form of connective tissue but is not as tough and rigid as bone. The main difference in the cartilage and bone is the mineralization factor. Bones are highly mineralized with calcium salts while cartilages are not. Joints: Joints are important components of human skeleton because they make the human skeleton mobile. A joint occurs between “two or more bones”, “bone and cartilage” and “cartilage and cartilage”. Divisions of Human Skeleton: Human skeleton...

Main body system • Skeletal System • Muscular System • Nervous system • Respiratory system • Digestive System • Male Reproductive System • Female Reproductive system • Cardiovascular system • Urinary system • Endocrine system 1. Skeletal system The skeletal system is muscle that is connected to the skeletal to make a part of the mechanical system which moves the limbs and other parts of the body. The skeletal also relates the cartilages and joints of the human body which then creates the human skeleton. It is one of the main and important systems in the body. The joints are very important because they allow different types of movements at different locations to happen. However there are three components; • Bones • Cartilages • Joints Bones: Bones is a tough and frim form of connective tissue. It is the responsibility is to almost all strength of skeletal. Bone is the mineralization factor. Bones are highly mineralized with calcium salts Cartilages: The cartilage is a form of the connective tissue however it is not as tough and frim as the bone and the main difference in the cartilage and bone is the mineralization factor. This is because the bones are highly mineralized with calcium salts whereas cartilages are not. Joints: the joints are important components of the human body because they allow the body to move about, the joints...

Seven Organizational Approaches

...Organizational Approaches The healthy human body can be studied in seven different ways. These ways include the following; body planes and cavities, body cavities, quadrants and regions, anatomy and physiology, microscopic and macroscopic, body systems, and medical specialties. In order for the human body to be considered healthy it must have complete physical, mental, and social well-being. The seven different ways involve approaching the body from different angles by dividing or organizing the body. There are three main planes used to study the body: the coronal, sagittal, and the transverse planes. The coronal plane divides the human body vertically into front and back sections. The front section is the anterior or ventral, and the back section is known as the dorsal or posterior. The sagittal plane is a vertical plane that divides the body into right and left sections. There are two directions used when dividing the body in a sagittal plane- lateral and medial. The lateral direction moves from either side of the body toward the body’s midline. The medial direction moves in the opposite direction, from the body’s midline to either side of the body. The transverse plane is a horizontal plane that divides the body into bottom and top sections. The bottom half is known as the inferior section, while the top half is referred to as the superior section. In order for the human body to be studied in planes it must be in an anatomical position. The human body can be studied by its five cavities;...

Seven Approaches

...“When the human body's countless parts function correctly, the body is in a state of health or optimum wellness. The study of the healthy human body can be done in several different ways. Each way approaches the body from a specific standpoint and provides unique information about the body. Each approach divides and organizes complex information about the body in a logical way. These approaches include the following: body planes and body directions, body cavities, quadrants and regions, anatomy and physiology, microscopic to macroscopic, body systems, and medical specialties” (Turley, 2011). Body planes and body direction is one approach that divides the body into front and back, right and left, and top and bottom. The three main body planes are coronal, sagittal plane, and transvers plane. The body directions showcase the movement towards or away from the planes. The major directions are superior, inferior, anterior, posterior, medial, lateral, proximal, distal, superficial, and deep. “There are many times in medicine that a doctor has to record information in a medical record or tell another doctor the exact body part or location of disorders or damage to your body or an organ. To do that, there are standard terms for describing human anatomy including the body and its organs. These terms are often used to describe medical imaging such as CAT scans, PET scans and MRIs where the scans take pictures of the body in flat slices” (Media Partners, 2011). Body cavities are spaces...

Essay On The Lymphatic System

...that the lymphatic system is part of the circulatory system and plays three major roles which may include the removal of excess fluids including red blood cells from the body, absorption of fatty acids as well as helping to transfer fatty substances and chyle to the circulatory system. And, it helps in the production of lymphocytes, monocytes, and antibody producing cells which help to strengthen our immune system against any invaders that make us sick. Like the cardiovascular system, the lymphatic system is made up of vessels. Although, it lacks a heart that pumps blood such as what is obtainable in the cardiovascular system, the lymphatic system has got lymph which is produced as blood plasma that is discharged from the capillaries of the circulatory system via skeletal muscle contraction. The lymphatic system has also got valves and lymph nodes to prevent backflow. Information contained in my class notes point to the fact that lymph nodes can only be found at...

Seven Organizational Approaches

...organizational approaches to the human body. It’s imperative to understand how the human body works and complex systems. The seven organizational approaches are body cavities, body planes and direction, anatomy and physiology, quadrants and regions, medical specialty, microscopic-to-macroscopic, and body systems. Besides the importance of just understanding the human body, each can be used when applying knowledge to practical use in the healthcare industry. All of these approaches are imperative to learn and understand when in the healthcare industry. The body cavity is the study of body organs and cavities within them. Body cavities help divide the body into sections or compartments and help give organs a particular “place” in the body. Harris (2005) stated, “Humans have four body cavities: (1) the dorsal body cavity that encloses the brain and spinal cord; (2) the thoracic cavity that encloses the heart and lungs; (3) the abdominal cavity that encloses most of the digestive organs and kidneys; and (4) the pelvic cavity that encloses the bladder and reproductive organs.” .This type of approach is often used when a particular organ is being studied as an entire system like the gastrointestinal system that is in the abdominopelvic cavity or the brain in the cranial cavity. Body cavities can also be useful for observing how a disease affects numerous organs within the human body. Body planes and direction is the human body division. It involves four different...

Endocrine System

...The Endocrine System Dirty Sanchez BEH/225 Introduction to Behavioral Science 19 March 2014 Mrs. Piggy The Endocrine System Human behavior can be affected by several factors; a person’s upbringing, the surrounding environment, and one’s personality. These are all examples of what one sees on the outside of the body. Inside the body, there is a system that can have several effects on human behavior. This system is called the endocrine system. This system is made up of glands that secrete hormones into the lymph system, also known as the bloodstream. Glands such as the thyroid and adrenal secrete hormones that affect human behavior. The thyroid gland secretes thyroid hormones such as triiodothyronine (T3) and thyroxine (T4), which regulate the human body’s metabolism. The adrenal glands secrete hormones such as, adrenalin and noradrenalin which can be related to fear and anger. The endocrine system’s secretions of hormones throughout the human body plays a large role on how a human behavior. The Role of the Endocrine System Like the nervous system, the endocrine system goes hand-in-hand in controlling and coordinating the reflexes and reactions of the human body. The endocrine glands create and execute communications throughout the body that are just as important as the nervous system (Coon & Mitterer, p. 74, 2012). Through secretion of chemicals, also known as hormones, the endocrine system secretes these...

The Four Basic Human Body Structure Units and Their Functions

...The four basic human body structure units are cells, tissues, organs and systems which, all working together make the human body function. The cells are the core structure that make up the human body, although there are many different shapes, sizes and types they consist of three main parts, the cell membrane which maintains the shape of the cell and separates and controls the movement of material into and out of the cell, the nucleus which contains the cells DNA and determines its structure and function and the cytoplasm which is the fluid in the cell that contains the organelles which perform its specific functions. There are many cell functions dependant on the cell type but the generalised functions are molecule transport, reproduction and protein synthesis. Molecule transport is the transfer of material through the cell membrane, there are two ways this happens, diffusion and active transport. Diffusion is when molecules such as oxygen, carbon dioxide and water move from areas where there are many of the particles (high concentration) to areas with less (low concentration). Active transport is when substances are at lower concentration and require energy to be transferred. There are two means of active transport, endocytosis which is the movement of molecules from outside to inside the cell and exocytosis which is movement of molecules from inside to outside the cell, both performed via the formation of vesicles which package the molecules then fuse...
