• Breathing process is made easier by the combined action of diaphagm and ribs. Do you agree with this statement. explain? ​

Answer 1

Answer:

> DIAPHAGM is dome shaped when relaxed, with its convex surface projecting cranially into the thorax. It enlarges the thoracic cavity by flattening out its dome shape.

Answer 2

Explanation:

Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. 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.Breathing process is made easier by the combined action of diaphagm and ribs. Do you agree with this statement. explain? The relationship between gas pressure and volume helps to explain the mechanics of breathing. Boyle's Law is the gas law which states that in a closed space, pressure and volume are inversely related. As volume decreases, pressure increases and vice versa.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.
