How does the pulmonary artery deliver oxygen to the lungs?

The pulmonary artery and its branches deliver blood rich in carbon dioxide and lacking in oxygen to the capillaries that surround the air sacs. Carbon dioxide moves from the blood into the air inside the alveoli. At the same time, oxygen moves from the air into the blood in the capillaries.

What happens to the muscles in the lungs when you breathe?
