## TL;DR
Human Anatomy: Systems, Organs, and Function: Human anatomy studies the structure of the human body from cells and tissues to organs, organ systems, and whole-body organization.

## Core Explanation
Anatomy is often taught with physiology because body structures support body functions. Foundational topics include levels of organization, anatomical position and directional terms, body cavities, organ systems, and homeostasis.
