The lungs don't actually contract. all the work is done by muscles in the chest.
When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.

during the exhalation phase, the diaphragm relaxes, that is resuming its dome shaped position. The intercostal muscle likewise relax and the rib cage moves down deflate . ACHECHE from:Alkenneth Angelico O. Alderite
How do inhalation and exhalation impact diaphragm movement?
Diaphragm movement impacts inhalation and exhalation. It moves upward on exhalation.
What muscle separates the thorax and abdomen and aids in breathing?

The diaphragm relaxes during EXHALATION. Your diaphragm flattens when you inhale, creating more space for the lungs to take in more air.
What happens to a muscle when it relaxes?
all the muscle filaments move away from each other
Does exhalation occur when the diaphragm and rib cage muscles relax?
Yes, exhalation occurs when the diaphragm and muscles of the rib cage relax.
What does the diaphragm muscle do when air moves into the lungs?
The diaphragm moves down to make the lungs expand (inhalation)
The greatest water loss per day occurs?
through lungs (exhalation)
What happens when relaxation of the diaphragm and intercostal muscles increases intrapulmonic and intrathoracic pressure?
Exhalation describes the state when the diaphragm relaxes and intrapulmonic and intrathoracic pressure increases.
What is the changes in size of thoracic cavity during the contraction and relaxation of diaphragm?
When the Diaphragm contracts, it is pulled down, and is pulled back up when it relaxes.Also, when you inhale, it contracts. When you exhale, it relaxes.
