The study of the structure of the body is called Anatomy. This field focuses on understanding the organization and relationships of various body parts, including organs, tissues, and cells. Anatomy can be broken down into many sub-disciplines, such as gross anatomy, which examines structures visible to the naked eye, and microscopic anatomy, which involves studying tissues and cells using a microscope.
Physiology, while closely related, specifically deals with the functions and processes of the body’s systems rather than their structure. Biology encompasses a broader range of life sciences, including the study of living organisms and their relationships, while Chemistry studies the composition, structure, properties, and reactions of matter, which may include aspects of biological systems but not specifically the structural focus related to Anatomy. Hence, Anatomy is the most precise term for the study of body structure.
