A yawn is a very deep inspiration
It is very important that they cover you alveoli
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
Alveoli are very tiny air sacs found in the lungs where CO2 and O2 are changed.
the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.
the paouch like air secs at the smallest lenchioles is called alveoli.the walls of alveoli are very thin and they are sorrounding thin blood capllaries .it is in alveoli exchange of gaseouse takes place there are so many alveoli in blood so they provides very larges surface srea for cxchanges of gaseouse
No, alveoli do not have very thick walls. In fact, they have very thin walls composed of a single layer of epithelial cells, which facilitates efficient gas exchange between the air in the alveoli and the blood in the surrounding capillaries. This thin structure allows oxygen to diffuse into the blood and carbon dioxide to diffuse out easily.

If you didn't have Alveoli than you wouldn't live very long. Alveoli allow oxygen to enter the bloodstream, so without them you'd die within the first few minutes of your life.

Magellan didnt really have a human inspiration. He was a very curious man which i guess you could say was his inspiration to start the voyage around the world.
Gas exchange takes place inside the lungs in the alveoli. The alveoli are a "grape like" structure at the very end of the respiratory tract. The alveoli are composed of a very thin membrane that separates the blood vessels from the gas chambers. The thin membrane allows diffusion of oxygen into the blood stream and diffusion of carbon dioxide (CO2) out of the blood stream. Once the CO2 has diffused into the alveoli, it is exhaled.
