What are alveoli surrounded by?
the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.
Does the carbon dioxide travels into capillaries alveolar and out of the capillaries at the tissue?
In the alveoli
What are the small sacs in the lungs where carbon dioxide is exchanged for oxygen?
The humorus
What is the name of the tiny blood vessels that surround the alveoli in the lungs?
These are called the alveoli capillaries.
Oxygen passes into the capillaries that surround these sac?
Oxygen passes into the capillaries that surround the alveoli. The thin walls of the capillaries make this diffusion easier.
What are tiny air sacs surrounded by capillaries?
Alveoli.
What are the very small blood vessels that cover the alveoli?
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
Is it important that capillaries cover the alveoli?
It is very important that they cover you alveoli
What does the oxygen molecule do when it is in the alveoli?
It diffuses into the blood capillaries surrounding the alveoli.
