Question

What is the function of ribs and diaphragm in breathing?

Answer 1

Answer:

Diaphragm: Expands downwards into the abdominal cavity to allow for the lungs to expand as we inhale. As the diaphragm contracts the air is expelled from the lungs.

Ribs: The ribs protect the lungs and expand as you inhale to fascillitate space for the lungs to expand like the diaphragm.

Answer 2

Answer:

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