When
you breathe out
, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to make the chest cavity smaller. As the chest cavity shrinks, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
What causes the diaphragm to relax and move up?
Diaphragm's Role in Breathing
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
.
What happens when your diaphragm relaxes?
Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.
Upon exhalation
, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs.
Does the diaphragm move up or down when relaxed?
The diaphragm is a large muscle that sits at the base of the lungs. When a person inhales, their diaphragm contracts and moves downward, creating space for the lungs to expand and fill with air. When a person exhales, the diaphragm
relaxes and moves upward
, helping move air out of the lungs.
What will happen to the body if the lungs push up and the diaphragm relaxes?
When you breathe in, your diaphragm pulls downward, creating a vacuum that causes a rush of air into your lungs. The opposite happens
with exhalation
: Your diaphragm relaxes upward, pushing on your lungs, allowing them to deflate.
