Diaphragm (anatomy)

Diaphragm (anatomy)

The Diaphragm (pronounced: /ˈdaɪəˌfræm/) is a crucial muscle in the human body that plays a significant role in the respiratory system.

Etymology

The term "Diaphragm" originates from the Greek word diáphragma, meaning 'partition'.

Function

The primary function of the diaphragm is to facilitate breathing. It contracts and flattens when you inhale, creating a vacuum that pulls air into the lungs. When you exhale, the diaphragm relaxes and returns to its dome-like shape, pushing air out of the lungs.

Anatomy

The diaphragm is a dome-shaped muscle located beneath the lungs and heart, separating the thoracic cavity from the abdominal cavity. It is attached to the spine, ribs, and sternum.
