Question

what are the functions of ribs diaphragm and abdominal muscle in breathing​

Answer 1

Answer:

Function of parts in Breathing

Explanation:

Ribs diaphragm:

1. When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.

Abdominal muscle:

1. The muscles used in abdominal breathing are the diaphragm for inspiration and the abdominal muscles for expiration. During inspiration, the diaphragm contracts strongly, causing a large expansion of the thorax vertically. At the same time, intra-abdominal pressure increases and causes the abdomen to bulge.
