PSI Barbering Practice Exam

Which of the following is the study of the functions and activities performed by the body's structures?

1. Biology

2. Physiology

3. Anatomy

4. Pathology

The correct answer is: Physiology

The correct answer is physiology because it specifically focuses on the functions and activities of the body's structures. Physiology examines how different systems in the body work together, how they maintain homeostasis, and how they respond to internal and external stimuli. It delves into the biochemical and mechanical processes that sustain life, from cellular functions to complex organ systems. In contrast, anatomy is the study of the structure of the body and its parts, detailing their shapes, sizes, and relationships. While both anatomy and physiology are interrelated, physiology is distinct in its emphasis on function rather than structure. Biology is a broader field that encompasses various life sciences, including physiology and anatomy, but it doesn't exclusively focus on the functions of bodily structures. Pathology, on the other hand, deals with the study of diseases and the changes they cause in body structures and functions, rather than the normal functions themselves. Thus, physiology is the most appropriate choice for the study of functions and activities performed by the body's structures.
