...Methamphetamine also known as meth, chalk, ice, and crystal, is a powerful, highly addictive stimulant that affects the the whole human body. Meth is a white, odorless, bitter, powder that can be inhaled, injected, smoked and ingested. It was developed in the early 20th century from its “parent drug”, amphetamine, and was used originally as to treat nasal problems before it was used for recreational purposes. Meth causes the user to experience a sense euphoria, but aswell cause paranoia, decreased appetite, and leaves permanent and irreversible damages on the user’s body. Meth has been classified by the U.S. Drug Enforcement Administration as a Schedule II stimulant, which makes it legally available only through a nonrefillable prescription...

...Story of the Human Body Synthesis Paper Candance N. Marshall Evergreen State College Story of the Human Body Synthesis Paper The chapters in the book start with the evolution of the human body from the lands of Africa to the present day. The findings of bones that date back millions of years displays the evidence of such evolution. The findings support the theories the changes the human body went through in order to adapt to its surroundings and the initial transition into a bipedalism species. Adaptation and Transitioning When reading into the adaptations you can recognize the necessity of these major transformations that contributed to the major adaptations in the body such as the beginning of bipedalism, the shift to a non-fruit based diet as the rise of the hunter/gatherer emerged with the adaptation of a more athletic abilities; the development of larger brains and more noticeable cultural beliefs and rituals. Revolution1 The major variations that are effecting our current society originated from the Agricultural and Industrial revolutions. The modifications to our diets play a huge role in the presence of chronic illness in the world. Post Paleolithic World. Our bodies are not entirely adaptable to the world we live in, we can recognize this with the growing incidences of obesity and disease like type-2 diabetes. Diseases. Although the body has adapted to the many changes of the environment, cultural and biologically evolution continues while the rapid spread...

...Nathan Coulson What part of the body is most accurate for testing the temperature of a baby's bath water? Your hands are very unreliable at measuring temperature, one reason is because you can become used to extreme temperatures on your hands more readily than other parts of your body. For example, when you first put your hand in water it might feel very hot or very cold, but then as you keep your hand under water, you get used to it, and the water begins to feel more moderate than it really is. This is a very bad thing if you are trying to avoid scalding your baby! Scientists and doctors have proven that the elbow is the most reliable to test your babies bath water because the skin cells on the end of the elbow are more sensitive than any other part of the skin. If you test your baby’s bath with the end of your elbow you are less likely to scald them. What's the structure of the skin? The skin is the largest organ in the body. It has three main layers, the epidermis, the dermis and the subcutaneous layers. The epidermis is an elastic layer on the outside that is continually being regenerated. The dermis is the inner layer that includes the following Epidermis Dermis sweat glands- they produce sweat that travels through the sweat ducts Hair follies- are pits where hair grows. Hairs also play a part in temperature regulation. Source A Subcutaneous layer The subcutaneous layer under the dermis is made up of connective tissue and fat (a good...

The Human body is criticized or checked up to designate a romantic attraction, a perfect employee, a perfect soldier, among others. The art made of the human body is a representation of the thought at the time and the artist, which is something that will be analyzed with the Greeks, Medieval and Renaissance point of view toward the human body. For the Medieval view of the Christian body, we will use the Coffin Lid of Francisco De La Sarra. During the Medieval times, the lives of the Christians were ruled by the Pope and God. The art was meant to let all Christians understand that by living a good life they will be rewarded in the afterlife...

...The Human Body –Stages of Child Development p.54 Write a summary of each of the 3 stages of childhood development. Two and a half-year-old Moira learns 10 new words a day. Quickly she also learns self-awareness. Unfortunately, this means she can articulate her needs and throw tantrums if she does not get what she wants. Maybe children have an instinctive knowledge for language and get the grammar right virtually all the time. Moira make word herself for plural for mouse by adding an S. So how to kids soak up new language so fast? The reason is that children always felt serious dangers. So they, by instinct, learn the vast range of words as fast as possible to better provide against squalls, to survive. Theory of mind is our ability to understand that other individuals have their own minds, with different thoughts, feelings, desires, emotions, motivations and goals. It’s a crucial ability for creating and maintaining a complex society and as far as we know humans are the only species that can do it. This important, complex and uniquely human ability is based on being able to recognize that I am separate from you; that I am a distinct, physical entity that can be recognized in the mirror. Chimpanzee can recognize themselves in the mirror but monkeys cannot. Ostensibly this makes sense, since chimpanzee have bigger brains than monkeys and display a wider range of more complex behavior. There’s even some suggestion that chimpanzees have a sort of theory of mind. But humans are...

...This essay will be based on how the human body is far more impressive than the ferrari f12 berlinetta and after this essay i am positive that you will believe that the Human body is far more impressive then some car. For example one of the main reason why the ferrari is absolutely no match for the human body is that can it repair itself in the way that the human repair itself with blood cells and tissue. Another underlying reason is that human control cars so without humans they can't do anything so how could they be more impressive is they can't be impressive without Humans. The final reason of why Humans are way more impressive is that they cant even have nearly as much as the genetics and do the things we do. The real definition of cars...

...Approaches to studying the Human Body Approaches to studying the Human Body There are seven approaches one can take to study the human body. Those approaches are • Body planes and body directions • Body cavity • Quadrants and regions • Anatomy and physiology • Microscopic to macroscopic • Body systems • Medical specialties The body planes and the body directions are used when trying to describe the location on the body it can also be called anatomical directions. For example anterior is used for front or in front of and posterior is for after, behind, following. The body cavity is being used when studying any fluid filled space in the multicellular organism. Like the pelvic cavity, ventral cavity dorsal cavity and so forth. Regions and quadrants are used to determine what part of the body you are studying, we determined that with planes there is front and back and now with regions and quadrants it gets a little more specific. Anatomy and physiology are used to determine how each part of the body work and why it works the way it does. Microscopic to macroscopic is the study of the bodies smallest parts and how they come together to make a large complex system. Body systems are how the organs function in the body, how the heart beats how we breathe. Medical specialties are the treatment for a specific area in the body. • In health care each organizational approach is used differently. The quadrant system is used more so when health care workers are doing...

...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 generalized 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 to areas with less. 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 through the formation of vesicles which package the molecules...

There are three main types of RNA.a. mRNA - messenger RNA, copy of the DNA, sent out into the cytoplasm. Contains the genetic code for making proteins.b. rRNA - ribosomal RNA, building site for proteins. Reads the mRNA and allows the right tRNA to bring in the right amino acid.c. tRNA - transfer RNA, brings the right amino acid to the rRNA.3). ATP = adenosine triphophate, Adenosine is made from adenine and a 5 carbon sugar. It is the energy source for all living organisms cells.What is the function of carbohydrates? Carbohydrates provide the body with a source of fuel and energy that is required to carry out daily activities and exercise. Any extra energy is stored in the body until its needed. Our bodies need a constant supply of energy to function properly and a lack of carbohydrates in the diet can cause tiredness or fatigue, poor mental function and lack of endurance and stamina. Carbohydrates are also important for the correct working of our brain, heart and nervous, digestive and immune systems. Digestion: food enters the mouth, being chewed by...

...Introduction This essay will consider the structure and function of the 11 systems within the human body. It will detail the interrelationship between the nervous system and the musculoskeletal system and between the circulatory system and the lymphatic system. It will then explain the roles of the circulatory and lymphatic systems in the immune response and the role of hormones in metabolism. Human Body Systems The human body is made up of 11 separate but interconnected systems (Sherwood, 2007). These are the skeletal, muscular, circulatory, respiratory, digestive, excretory, nervous, integumentary, immune, endocrine and reproductive systems. The success and survival of the human body is dependent on the ability of separate body systems to work together. The skeletal system provides structure for the human body, stores minerals, produces blood cells and provides protection for delicate organs (Kelly, 2004). 206 bones are connected with ligaments, muscles and tendons, with cartilage, a softer cushion like material, providing protection in jointed areas. Body movements are controlled by the muscular system, with these muscles being connected to bones via tendons (Adams, 2004). Stimulation of these muscles by the nervous system causes contraction and the resulting movement of bones to which they are attached. A number of involuntary muscles ensure the respiratory and circulatory systems continue with contraction of the heart and lungs (Adams, 2004). The heart is central...

...n your own words, describe how the human skeleton supports the human body. The human skeleton is the framework of the human body. It supports the softer tissues, provides points of attachment for most skeletal muscles and protects many vital organs. It also maintains the body’s’ shape. The skeleton is made up of bones that can be categorised according to one of five functions that they perform; • Shape and support; The skeleton provides the shape and support that gives the body its shape. As well as providing gravitational support, it supports the softer tissues and provides points of attachments for most skeletal muscle. • Movement; Some bones provide leverage for movement. Most of the bones are connected to other bones at flexible joints, which allow the skeletal framework a high degree of flexibility and movement. The bones are attached to tendons of the skeletal muscle and the ligaments of the joints. They then act as levers and pulleys to aid the contraction of the skeletal muscles into movement. • Protection; The skeleton provides protection for the body’s vital organs, reducing risk of injury to them. Blood production; Red blood cells and some white blood cells are manufactured by the bone marrow which is found in the cavities of some of the larger bones. Haematopoiesis is the formation of blood cells. This normally takes place in the red marrow of the bones. Each bone consists of a compact outer shell and a spongy centre. The centre contains the bone marrow which...

...recycled within and between ecosystems. Elements pass from one organism to another and from one part of the biosphere to another through biogeochemical cycles, which are closed loops powered by the flow of energy. The Water Cycle Water moves between the ocean, the atmosphere, and land. Evaporation is the process in which water changes from a liquid to a gas. Transpiration is the process in which water evaporates from the leaves of plants. Nutrient Cycles The chemical substances that an organism needs to survive are called nutrients. Like water, nutrients pass through organisms and the environment. Carbon Cycle: Carbon is a key ingredient of all organic compounds. Processes involved in the carbon cycle include photosynthesis and human activities such as burning. Nitrogen Cycle: Nitrogen is needed by all organisms to build proteins. Processes involved in the nitrogen cycle include nitrogen fixation and denitrification. • In nitrogen fixation, certain bacteria convert nitrogen gas into ammonia. • In denitrification, other soil bacteria convert nitrogen compounds called nitrates back into nitrogen gas. Phosphorus Cycle: Phosphorus is needed for molecules such as DNA and RNA. Most of the phosphorus in the biosphere is stored in rocks and ocean sediments. Stored phosphorus is gradually released into water and soil, where it is used by organisms. Nutrient Limitation A nutrient that, in short supply, can limit the productivity of an...

...like walking, sitting or even flinching when you get a cut on your finger but these actions are actually controlled by a very complex set of internal circuits similar to a light when you turn on the switch that is called the central nervous system (CNS). There are three major parts that make up the CNS, they are the brain, spinal cord and peripheral nervous system (PNS). The CNS transmits information to the brain through transmitters and receptors that are all throughout our body and emits a command to a muscle or gland if necessary. Sometimes the answer comes instantly as a reflex or automatic response or other times may take considerably longer, requiring cooperation among many parts of the brain. (Brodal, 1992). The central nervous system not only transmits movement but also creates an equilibrium system that keeps the body balanced as you perform actions like walking or bending. To do this the cns sends electrical impulses to certain muscle and joints to create a balanced position for the body. (E. Bizzi, 1992) Traumatic brain injury (TBI) has a very dramatic affect on the person and their family whether permanent or temporary but what exactly causes it. Brain damage following a traumatic injury is a result of direct or immediate mechanical disruption of brain tissues, or primary injury and indirect or delayed mechanisms which involve initiating the acute inflammatory response, edema formations and swelling.

...the four basic human body structure units and their functions The four basic human body structures and their functions are as follows: • Cells • Tissues • Organs • Systems Cells Cells have been identified as the simplest unit of living matter that can maintain life. A cell is the simplest and smallest unit of living matter and cells can live independently and can also reproduce themselves. Cells exist in a varity of shapes and sizes including elongated, oval, and square, cells also have many different function. A group of cells is called a tissue and the study of the structure, form of cells and tissue is called histology. Tissues Tissue is a group/organisation of a number of similar cells, not all identical but from the same origin, that carry out a similar function, which also consists of varying amounts and varity of non-living, intercellular substance between them. It is the level between cells and organs. There are four types of tissue: Epithelial – tissue that is widespread throughout the body. They form the covering of all the body surfaces and are the main tissue found in glands. Epithelial tissue performs a variety of functions that include protection, secretion, absorption, filtration and sensory reception. Connective - tissue that binds structures together, and forms a framework and support for organs and the body as a whole. Connective tissue also acts as a transport system for substances to be carried around the body, and helps store...
