Question

4 Diaphragm plays ut important role in breathing justify​

Answer 1

The diaphragm, often called the thoracic diaphragm, is a large muscle that separates the chest from the abdomen. This muscle plays an important role in breathing as its alternating movement helps you inhale and exhale.

It squeezes downward when you breathe in, making a vacuum that causes a rush of fresh air into your lungs. The opposite happens when you breathe out.

Answer 2

Answer:

DIAPHRAGM PLAYS A IMPORTANT ROLE IN BREATHING.

Explanation:

1. The diaphragm, often called the thoracic diaphragm, is a large muscle that separates the chest from the abdomen.
2. This muscle plays an important role in breathing as its alternating movement helps you inhale and exhale.
3. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.
4. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
5. The diaphragm is important as it is the primary muscle that facilitates breathing.
6. When the diaphragm contracts, it becomes smaller, causing the lungs to expand in the chest cavity and allowing air to move into the lungs (inhaling).
