Capillaries The smallest of the blood vessels: capillaries.
Capillaries surround the air sacs in your lungs. These thin-walled vessels facilitate the diffusion of gases into the bloodstream.

The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
Oxygen exchanges with CO2 (Carbon dioxide) to "purify" blood. This takes place in the aveoli (in the lungs) the blood is transported via blood vessels. Kidneys also purify blood
Capillaries are the blood vessels that surround the alveoli, or air sacs, in your lungs. These capillaries are the site of gas exchange.
how does the exchange of gasses between the aveoli and blood happen
Space that surround the cells of a given tissue
The capillaries are the small blood vessels that surround each alveolus, or air sac.
You didn't finish your question so we don't know what you're asking. Surround what?
Aveloli are the structures within the lungs, at the terminal end of bronchioles. They are not blood vessels. Aveoli resemble a cluster of grapes hanging off the smallest branches of a tree, with the tree upside down. The main bronchus in the upper chest is like the tree trunk, the bronchi branch and thin to bronchioles, then end at the aveoli. There O2 and CO2 exchange takes place.
