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 type of blood vessels surrounds the alveoli?
The smallest blood vessels of the body = capillaries
The blood vessels surrounding the alveoli are?
capillaries
What does the alveoli do when you breathe out?
It gives off the Co2 which is produced in the blood vessels covering the alveoli
What is the lining of the blood vessels made up of?
Alveoli
What passes from the alveoli in the lungs into the blood vessels?
ravioli
What blood vessel takes blood around the alveoli?
The capillaries carry the blood around the alveoli.
What is the body organ which oxygen passes through to capillaries?
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
What will happen to carbon dioxide as blood flows around the alveoli?
The CO2 is diffused back into the alveoli, where, by the diaphragm, is pushed back into the environment by atmospheric pressure.
The tiny air sacs in the lungs that take oxygen from the air and put it into the blood?
These tiny air sacs are called alveoli. These alveoli are surrounded by capilaries tiny blood vessells. These capilaries have holes that are to small for blood cells to escape but are big enogh for oxygen molecules to pass in to the blood stream and attach to the haemoglobin in your blood.
Why are there a large number of blood vessels around each alveolus?
because the oxygen needs to pass through alveoli and there is alot of cells around to be transported!!
Is blood transported through the alveolis?
No, blood is not transported through the alveoli. The alveoli are tiny air sacs in the lungs where gas exchange occurs between the lungs and the blood vessels. Oxygen is taken in from the air and carbon dioxide is removed from the blood in the alveoli.
