What else can I help you with?
What are the very small blood vessels that cover the alveoli?
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
What are alveoli surrounded by?
the blood surround Alveoli in order to gas exchange between the Alveoli and red blood cell.
Why do capillaries cover the alveoli?
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.
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.
How are oxygen and carbon dioxide exchanged between the alveoli and the capillaries?
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.
What does the oxygen molecule do when it is in the alveoli?
It diffuses into the blood capillaries surrounding the alveoli.
What surrounds the blood capillaries?
Alveoli
The are surrounded by blood capillaries?
Alveoli
