Anatomy Practice Exam

The study of physiology primarily focuses on the functions of body systems. It encompasses how various organs and systems work together to maintain life and health, including processes such as respiration, circulation, digestion, and neural function. Physiologists investigate the mechanisms that regulate bodily functions at various levels, from cellular to organ systems, and how these processes interact with each other. This focus on function distinguishes physiology from other related fields. For example, while the structure of the body pertains to anatomy, the study of the chemical composition of cells is more aligned with biochemistry. The evolutionary history of organisms, on the other hand, is the domain of evolutionary biology and does not directly address the functioning of existing biological systems. Understanding physiology is crucial because it provides insight into how normal bodily functions can be affected by disease, lifestyle, and environmental factors, making it essential for fields such as medicine, biology, and health sciences.
