Basic Human Anatomy

The human body is made up of many different organs that each have a specific role in maintaining the good health of an individual. The brain is involved in thought, reasoning and, in general, controling our actions; the heart pumps blood around our body supplying all the organs with essential nourishment; the lungs load our blood with oxygen that helps supply the energy we need to function; the stomach, kidneys, liver, intestine and bladder all function in unison to extract nutrients from our food and dispose of unwanted toxins. Each organ plays an essential and unique part keeping us alive (see diagram below).

(Editors Note: If you are interested in learning more about human anatomy and physiology, or require high-definition images of various human organs and systems then we recommend you take a look at this Human Anatomy and Physiology Course. We have had a comprehensive look through this guide and find it to be one of the best products available on the web, at a surprisingly low price. This study course is particularly useful for biology, nursing or medical students, but we would actually recommend it to anyone wishing to learn more about the human body and its functions).

In order to carry out its appointed role, an organ comprises of billions of cells of different types, each arranged in tightly controlled structures that form the overall architecture of the organ. It is the cells that are actually responsible for the proper functioning of the organ. If something goes wrong with an organ, then in order to treat it, we must restore the proper functioning of these cells.
