Organs[edit | edit source]

A heart

Many living things have organs. Your heart, brain, lungs, liver, and kidneys are all examples of organs.

Organs are made up of two or more tissues.

All organs have something that they do to keep you healthy. For example, the heart pumps blood, and the lungs give you air.

Organs work together in groups called organ systems.
