The Levels of Body Organization
Captions available
The idea
The body is organized in ascending levels: cells form tissues, tissues form organs, and organs form systems.
In practice
Muscle cells form muscle tissue, which forms the heart, part of the cardiovascular system.
Where people slip
Each level is built from the one below it. A term naming one level does not name another.
