Physiology is the link between basic science and medicine. The great beauty of physiology is that it integrates the individual functions of all the different cells, tissues, and organs of the body into one functional whole, the human body.

In fact, the human body is much more than the sum of its parts, and life is based on this total function, not just the function of individual parts of the body isolated from each other. This brings us to an important question: How do the separate organs and systems coordinate to keep the entire body functioning properly?

Fortunately, our bodies are endowed with a vast network of feedback controls that strike the necessary balances without which we could not live. Physiologists call this high level of internal body control homeostasis. In disease states, functional balances are often seriously disturbed and homeostasis is impaired. And, when even a single disturbance reaches a limit, the whole body can no longer live.
