When you breath in the diaphragm pushed upwards?

When you inhale, your diaphragm contracts (tightens) and moves downward. This creates more space in your chest cavity, allowing the lungs to expand. When you exhale, the opposite happens — your diaphragm relaxes and moves upward in the chest cavity.

Which process causes the diaphragm to move back up?

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.

Why does the diaphragm need to move up and down?

As you breathe in, your diaphragm contracts and flattens out. This allows it to move down, so your lungs have more room to grow larger as they fill up with air. ... Your rib muscles also lift the ribs up and outward to give the lungs more space.

What is the role of diaphragm and ribcage in breathing?
