What happens to cause air to be exhaled from the lungs?
the diaphragm relaxes and that causes the ribcage to compress (get smaller) this pushes air out, and you have exhailed

The diaphragm moves down, and the intercostal muscles pull the ribsup and out. Both movements increase the volume of the chest cavity,thus reducing the pressure in the lungs. …Air flows in from theoutside to equalise the pressure.
When this happens, your lungs and the rib cage (with muscles between each rib) expand when inhaling, and return to their previous size.
The air you exhale normally contains 19% less oxygen than inhaled air, with a 4% to 5% level of carbon dioxide and other gases, along with added water vapor. (Which is why you… can rebreathe it to control "hiccups".) Your body will continue to remove the remaining oxygen and add more carbon dioxide until the exhaled air is almost all nitrogen and CO2. So if you had only this air to breathe, your body would not be able to keep functioning and you could pass out and eventually die. This is the same situation as when one or more persons are trapped in a closed space with a limited amount of air. The considerable oxygen content (17%) in exhaled air allows mouth-to-mouth resuscitation in CPR.
okay, you breathe in, the air goes to your lungs, you breathe out, and the air comes out. sometimes it even comes out your wee wee, and that's called a QUEEF
The diaphragm rises. CO2 is forced out. With freeing the CO2 from Hgb and the lungs, the Hemoglobin can now pick up new oxygen molecules. The volume of the thoracic cavity… decreases.
The intrapulmonary pressure is greater than the atmospheric pressure and air is going to flow from high pressure to low pressure.
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. This is done because the lungs become smaller
It doesn't. Exhale means breathing out, when air leave the lungs.
when you inhale your lungs expand when you exhale they deflate because the air leaves the lungs.
When you breathe in, your diaphragm will contract, causing your lungs to expand and suck in air. When you breathe out, your diaphragm will relax, causing your lungs to shrink …and force out air.
By not breathing
So the blood can be oxygenated
The air that can not be exhaled is called residual volume. TV = the amount of air displaced during normal breathing. IRV = The amount of air that can be taken in forcibly …beyond tidal volume Erv= The amount of that can be expelled forcibly. Vital capacity = the total amount of exchangeable air. Total Lung capacity = TV + IRV + ERV + RESIDUAL VOLUME
