Anatomy and physiology are two closely related fields of study within the broader discipline of biology.

Anatomy is the study of the structure and organization of living organisms. It focuses on the identification and description of different body parts, organs, tissues, and cells.

Anatomy involves studying the shapes, sizes, locations, and relationships between body structures. It can be further divided into gross anatomy, which examines structures visible to the naked eye, and microscopic anatomy, which analyzes structures at the cellular and molecular levels.

Physiology, on the other hand, is the study of how living organisms function and how their systems work together to maintain homeostasis, or internal balance.

Physiology explores the mechanisms and processes that occur within cells, tissues, organs, and systems to carry out various bodily functions. Physiology includes the study of functions such as respiration, digestion, circulation, metabolism, sensory perception, and movement.
