The large number of alveoli increases the surface area over which gas exchange can occur, allowing the blood to become oxygenated more quickly.
The millions of alveoli increase the efficiency of the lungs in absorbing oxygen and expelling carbon dioxide.

Each lung houses about 300-400 million alveoli.
Human lungs can hold four to six liters of air. The lungs contain about 300 million alveoli. The right lung is slightly larger than the left.
The pleura. I suggest you do a web search on this for a diagram, and so you understand the different layers and where else the pleura can be found.
300 million to 400 million alveoli are in each lung. Each of the alveoli receives blood from the circulatory system capillaries. It replaces carbon dioxide and other blood wastes with oxygen. The circulatory system then delivers the oxygen to cells throughout the body, bringing more wastes back to the lungs.
There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood – also known as gaseous exchange.The alveoli have a very large surface area – in fact if all of the alveoli in your lungs were spread out flat they would cover the area of a tennis court.
300 million per lung
because it does
There are approximately 300 million alveolar sacs in the human body. The range in size from 70-300um(micro meters) in Diameter.
It connects to the ends of the bronchioles, there fore, i'd say, in the lung at the end of the bronchioles.
