Air (about 20% oxygen) is inhaled and filtered through the nose. Then it passes through the trachea, bronchi, and the bronchioles. There are only two main bronchi that lead into many bronchioles of decreasing size. The smallest of these open up into sac-like structures in the lungs called the alveoli. The alveoli are surrounded by capillaries, from which the oxygen diffuses into the blood stream and the carbon dioxide diffuses out. Then, the oxygen-depleted, and carbon dioxide-rich, air is exhaled out by the same route, but in the opposite direction.

∙ 11y agoThere is a muscle in the body called the diaphragm which (expands and contracts your lungs), and when your lungs expand, you breath in, and vise versa and the oxygen goes into these small chambers with red blood cells passing by and picking up the oxygen when it comes.
The parts in brackets are incorrect i felt some improvements needed to be made:
The diaphram does not expand and contract you lungs like this person has written that is the air coming into them that expands them and the air leaving them that contracts them.

Air is forced into the lungs by the contraction of the?
Actually, air isn't forced into the lungs my the contraction of any muscle, but by the relaxation of the Diaphragm, along with the Intercostalis muscles on the ribs and the smooth muscle on the lungs. When your diaphragm contracts, it pushes air out of your lungs. When it relaxes, air is drawn in to the lungs. The intercostalis muscles also help move the ribs when the lungs move as your breath. There is one set on the ribs and one set in between each rib.Hope this helps!
