Diaphragm

Vedclass · Answer

(A) Step $1$: The process of breathing (ventilation) involves the movement of air into and out of the lungs.Step $2$: The diaphragm is a dome-shaped muscular sheet that separates the thoracic cavity from the abdominal cavity.Step $3$: During inspiration, the diaphragm contracts and flattens, increasing the volume of the thoracic cavity, which decreases the pressure inside the lungs, causing air to rush in.Step $4$: During expiration, the diaphragm relaxes and moves upward, decreasing the thoracic volume and forcing air out of the lungs.Step $5$: Therefore, the diaphragm is the primary muscle responsible for initiating these movements.
