Question

Which way do your ribs move when you breathe in and out?

Answer 1

Answer:

When you breathe in, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, allowing your lungs to 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.

Answer 2

Answer :

Breath in : when we breathe in the muscles between the ribs contracts causing the rib cage to move upward and outward.

The diaphragm contracts and moves downward.

Breathe out : when we breath out the muscle between between the ribs relax causing the rib to move downward and inward.

Diaphragm relaxes and moves upward.
