Levels of Organization

Atoms, the smallest stable units of matter, combine to form molecules with complex shapes.

Different molecules can interact to form larger structures.

A tissue is composed of simular cells working together to perform a specific function.

An organ consists of 2 or more different tissues working together to perform specific functions

Organs interact in organ systems (like the heart pushing blood into the blood vessels...all part of the cariovascular system)

All of the organ systems of the body work together to maintain life and health.
