Introduction We know a lot about the human anatomy‚ its physiology‚ and how to treat the diseases that tend to disturb the balance between them‚ but‚ that was not always the case. It has really been that only in the past few centuries‚ scientists were able to dissect and experiment on other humans. Such experiments were the main contributors to our current knowledge in some fields of science‚ especially medicine. Dissections performed on rabbits‚ mice‚ chimpanzees‚ and other animals‚ along with some

Organisation of the human body. Jade Roberts. Barbara. P1‚ P2 AND P3. Health and Social Care level 3. 1 In this booklet I will be explaining what the main components and functions are of the cells. I will also be outlining the structure of the main tissues in the body and the gross structure of all the body systems. 2 The components and functions of cells. Cell membrane All organisms have something in common‚ they all have a cell membrane. The cell membrane is a barrier that separates a cell

Respiratory system is quite obvious given that as human beings we need this system to help us with our most fatal tasks of breathing. Although the importance is assumed and acknowledged‚ many do not really get the whole concept of the Respiratory system. For example‚ how it works? Why it works? And what all is involved. These questions and others will be strategically answered in the following work. The Respiratory System delivers oxygen to the body and takes the carbon dioxide away. This system

vital things in our lives and the chemistry they are made of. You are what you eat. But do you recall munching some molybdenum or snacking on selenium? Some 60 chemical elements are found in the body‚ but what all of them are doing there is still unknown. Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen‚ carbon‚ hydrogen and nitrogen‚ with a lot of that in the form of water. The remaining 4 percent is a sparse sampling of the periodic table of elements.

NERVOURS SYSTEM: NEURONS: * STRUCTURE AND FUNCTION: Specialized cell transmitting nerve impulses; a nerve cell. Neurons have specialized projections called dendrites and axons. Dendrites bring information to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Information is transmitted to the receiving cell at junctions via chemical messengers called neurotransmitters. At this juncture‚ the neuron transmitting

The human body is composed of many different types of cells. Cells are composed of many different types of molecules. Molecules consist of one or more atoms of one or more elements joined by chemical bonds. An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons which can produce free radicals. The free radicals can start chain reaction in the body and cause damage to cells and important chemicals in the body. Free

Week one written assignment for Kinesiology Bronwyn Oihus Abstract As humans our bodies are made up of several types of tissues‚ organs‚ bones muscles and nerves. I am going to talk about the joints of the skeletal system. The skeletal system gives us our shape and protects the inner structures of our bodies. In this system there are areas where 2 or more bones are held together in one of three ways. These are called joints and the bones and movement of the bones classifies the type of joint
