Question

The size of the chest cavity increase during inhalation is true or false

Answer 1

Answer:

True.

During inhalation the size of chest cavity increases as diaphragm contracts this pulls in the air from outside to the lungs.

Answer 2

Yes it,s True

Because

When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.

Hence the size of the chest cavity increases during inhalation is a true statement.

So, the correct answer is True.
