Question

what is the role of diaphragm and intercoastal muscles in the mechanism of breathing​

Answer 1

Answer:

Here:

Explanation:

The base of the sternum, the lower sections of the rib cage, and the spine are all connected by the diaphragm. When the diaphragm contracts, it lengthens and widens the chest cavity, allowing the lungs to expand. The intercostal muscles aid in breathing by moving the rib cage.

Answer 2

Answer:

Role of Diaphragm:-

The diaphragm, located below the lungs, is the major muscle of respiration. ... Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.
