What term refers to the study of body function?

The term that refers to the study of body function is physiology. This branch of biology focuses on understanding how various systems, organs, and cells in the body work together to support life. Physiology examines the mechanisms and processes that contribute to normal functioning and how these functions are regulated.

In contrast, anatomy pertains to the structure of the body and its parts, highlighting where they are located and how they relate to each other. Histology involves the microscopic examination of tissues, studying their composition and structure. Pathology, on the other hand, is the study of disease, including its causes, mechanisms, and effects on body systems. Therefore, physiology specifically addresses how the body operates, making it the correct answer to the question about body function study.
