Alveoli are the tiny sacs in the lungs that are the powerhouses of the respiratory system. That is where oxygen-spent blood gives up its carbon dioxide and becomes re-charged with oxygen.
Lung alveoli are the ends of the respiratory tree, branching from either alveolar sacs or alveolar ducts, which like alveoli are both sites of gas exchange with the blood as well. Alveoli are particular to mammalian lungs.

∙ 15y agoAlveoli are the end branches of the respiratory system. They are an awesome place for gas exchange because their walls are very thin, which makes it easy for oxygen and carbon dioxide to transfer.They have a very large surface area and they are close to the capillarys so they can get a good supply of oxygen quickly.

What are the alveoli and what happens in them?
the alveoli is happen the blood
Describe what happens in the alveoli sacs?
When we inhale in and out oxygen moves from the alveoli to blood carbon dioxide moves from blood to alveoli.
What happens in the alveoli-?
Gaseous exchange takes place in the alveoli where carbon dioxide from the bloodstream diffuses into the air.
What happens to carbon dioxide in the blood that flows through the capillaries in the alveoli?
alveoli take co2 from your blood and turns it into gas
Where in the lung does exchange of O2 and CO2 take place?
It takes place between the alveoli and the blood capillaries
Where does the oxygens exchange take place?
It happens in the Alveoli. The Alveoli is a balloonlike air sacs that is found at the end of each end of bronchiole.
What happens when blood passes by alveoli?
blood take oxygen from blood.
What happens to the oxygen when it reaches the alveoli?
oxygen enters the blood and carbon dioxide
What happens to the carbon dioxide in blood when it flows through the capillaries in the alveoli?
The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.
What happens to carbon dioxide in the blood when it flows through the capillaries in the alveoli?
The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.
What happens to amount of fresh air entering alveoli when tidal volume declines?
What happens is that the air volume entering the alveoli also decreases. Tidal volume is the quantity of air that enters and leaves the lungs during quiet breathing.
What happens to Carbon dioxide in the blood that flows in the alveoli?
it filters your lungs which causes you to exhale
