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
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.
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.
Do capillaries surround alveoli?
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
The are surrounded by blood capillaries?
Alveoli
