## TL;DR
Human anatomy is the study of body structure. It describes organs, tissues, bones, muscles, vessels, nerves, and body systems, and it pairs with physiology, which explains how those structures work.

## Core Explanation
Anatomy can be organized by system: skeletal, muscular, nervous, cardiovascular, respiratory, digestive, endocrine, immune, urinary, and reproductive. It can also be studied by level, from cells and tissues to organs and whole-body regions. The nervous system, for example, includes the brain, spinal cord, and peripheral nerves.

## Detailed Analysis
Good anatomical claims need clear scope. Some statements describe standard adult anatomy, while others vary by age, sex, development, pathology, or individual anatomical variation. Public-facing summaries should avoid unsupported exact counts or performance-like claims unless the source explicitly supports them.
