Body systems

Built to work together

Move from the whole body to the system you want to understand. Each guide connects structures, functions, and clinical context.

Muscular system

Movement, posture, and heat production through more than 600 muscles.

Skeletal system

The framework of bones and joints that protects and supports the body.

Nervous system

The rapid communication network connecting brain, spinal cord, and body.

Cardiovascular system

Heart and vessels transporting blood, oxygen, and nutrients.

Respiratory system

The organs and passages responsible for breathing and gas exchange.

Digestive system

Organs that break down food and absorb nutrients for the body.

Overview

One body, many levels

Human anatomy describes the form and organization of the body. It can be explored at several scales: from organ systems that coordinate broad functions, to regions such as the thorax or upper limb, down to the tissue layers that form an individual structure.

11major organ systems
206bones in the adult skeleton
600+named skeletal muscles

The atlas uses consistent directional terms and layered illustrations, helping you build a mental map that remains useful as topics become more detailed.
