- 1. Physiology is the branch of biology that deals with the normal functions of living organisms and their parts. It focuses on how individual cells, tissues, and organs work together to maintain the health and proper functioning of the body. By studying physiology, scientists can gain insights into the mechanisms underlying various bodily processes such as respiration, digestion, circulation, and reproduction. Understanding physiological principles is essential for diagnosing and treating diseases, as well as for optimizing overall health and well-being.
