A) Anatomist studies the structure of temperature sensors in the body.
Physiologist studies how the body detects dropping body temperature.
An anatomist studies WHAT the structures are of humans (and other living organisms). Anatomy can be macroscopic or microscopic and discusses the way the parts (from minute to big) interact to form a functional unit. The study of anatomy is often paired with the study of physiology, but the two are distinct from each other. Physiology covers HOW and WHY the parts function. A physiologist specializes in the study of living organisms’ functions, activities and organic processes.
