The walls of the alveoli and capillaries are thin enough to allow the
exchange of gases. In your lungs, blood exchanges carbon dioxide
for oxygen. Oxygen passes into the bloodstream through the walls of
the alveoli. Waste products (carbon dioxide and water) pass out of the
bloodstream into the air as they move through the alveoli.
Breathing In and Breathing Out
Breathing involves two main activities: inhaling and exhaling. Inhaling
pulls air (and oxygen) into the lungs. Exhaling pushes air out of the
lungs, taking water and carbon dioxide with it. The lungs do not inhale
and exhale on their own because they are not made of muscles.
The movement of air in and out of the lungs happens because of the
diaphragm. This is the large muscle on the floor of the chest cavity that
causes breathing. When you inhale, the diaphragm pulls air into your
lungs. As the diaphragm contracts, the chest expands and air rushes
into the lungs. As the diaphragm relaxes, the chest shrinks and causes
air to leave the lungs.
if the diaphragm contracts more quickly than usual, your breaths come
in gasps and make a "hic" sound. You have the hiccups.
