What is physiology primarily concerned with?

Physiology focuses on the chemical and physical processes that occur within living organisms. This includes understanding how organs and systems function in response to various physiological demands, such as metabolism, respiration, and homeostasis. Through physiology, one learns how different systems interact and contribute to the overall functioning of the organism.

The emphasis on processes rather than structures distinguishes physiology from anatomy, which is more concerned with the physical structures of the body. While studying tissue on a microscopic level relates more to histology, the overall understanding of how living systems operate and maintain life is what makes physiology fundamental in biological sciences. Understanding these processes provides crucial insights into health, disease, and the functioning of ecosystems.
