Capillaries cover the alveoli in order to maximize the area for gas exchange between the lungs and the blood. Carbon dioxide is released from the blood through the capillary walls and into the alveoli, while oxygen is picked up from the alveoli through the capillary walls and into the blood.
It is very important that they cover you alveoli
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.
In the alveoli
The humorus
These are called the alveoli capillaries.
Oxygen passes into the capillaries that surround the alveoli. The thin walls of the capillaries make this diffusion easier.
Alveoli.
It diffuses into the blood capillaries surrounding the alveoli.
Oxygen diffuses from the alveoli into the capillaries, where it binds to hemoglobin in red blood cells for transport to tissues. Carbon dioxide diffuses from the capillaries into the alveoli and is exhaled from the body.
