Question

what are the functions of the following in breathing
1.ribs
2.diaphragm​

Answer 1

Heya mate!!

Ribs- The ribs protect the lungs and expand as we inhale to facilitate space for the lungs to expand like the diaphragm. The ribs then contract expelling the air in the lung.

Diaphgram - When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure inside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the lungs.

Hope it helps you dear✌️✌️
