Diaphragm

Key Stage 3

This diagram shows the position of the diaphragm in the breathing system.

The diaphragm is a wall of muscle separating the organs in the thorax from the organs in the abdomen.

The diaphragm is essential to allow vertebrates to breath air.

When vertebrates inhale the diaphragm contracts and when they exhale the diaphragm relaxes.
