What is the primary focus of the study of physiology?

The primary focus of the study of physiology is the examination of bodily functions. Physiology explores how various systems, organs, tissues, and cells in the body operate, interact, and maintain homeostasis. It investigates processes such as circulation, respiration, digestion, and reproduction, which are vital for sustaining life. Understanding these functions helps in appreciating how the body responds to external and internal changes, contributes to medical knowledge, and aids in the development of therapeutic interventions.

While the study of body structure is related to anatomy, and cell biology focuses on cellular processes, these disciplines fall outside the direct scope of physiology. Pharmacology, on the other hand, relates more to the effects of drugs on biological systems rather than the underlying functions of those systems themselves.
