What does the alveoli and blood capillaries have in common?
they are both one cell thick to let the gases diffuse
Why aren't the alveoli dry and not wet all the time?
The moistness of the alveoli allows for exchange of gases. This is the primary function of the alveoli, and the lungs. Gases can dissolve in water, but they can not dissolve in dry solid material. If the alveoli were dry, oxygen could not diffuse into the blood and carbon dioxide could not diffuse out. Such a person would suffocate.
What organ does the oxygen-carbon Dioxide take place?
Oxygen is brought into the blood, and carbon dioxide released from the blood, at the alveoli of the lungs. Gases diffuse across the alveolar membrane to enter or leave the blood.
What blood vessels do the exchange of gases occur?
the blood vessel which allows gas exchange to occur is the capillaries
How would thick-walled alveoli affect the exchange of the respiratory gases?
lower exchange rate,takes longer for gases to diffuse
When gases are exchanged between the alveoli and blood what body systems are involved?
The respiratory and circulatory systems are involved in the exchange of gases between the alveoli and blood. The alveoli are part of the lungs, and their surrounding capillaries are part of the circulatory system.
Describe structure and function of alveoli?
Its structure is that of a balloon, and that helps it function during inhalation because it opens up to allow air to make contact with a large area to perform gas exchange. The structure of the alveoli is that there are blood vessels wrapping around them. Then, oxygenin from the alveoli can enter the blood. The blood will give oxygen to all the body's tissues, and later, in the alveoli, carbon dioxide or CO2 can leave the blood and be exhaled. So, together, the alveoli, wrapped up by blood vessels, can bring oxygen to the rest of the body and also get rid of all the carbon dioxide.
What division of the respiratory system exchanges gases with the blood?
The alveoli.
Why are lung alveoli covered with blood capillaries?
The Alveoli in the lungs have a very good capillary network because this is where gas exchange occurs. There needs to be sufficient area to allow the red blood cells to expel their carbon dioxide and to receive oxygen across the capillary and alveoli walls.
The exchange of gases occurs in the?
In the lungs are small air sacs called alveoli. These alveoli are covered with blood capillaries. Oxygen and Carbon Dioxide diffuse through the alveolar capillary membrane. Oxygen diffuses from the alveoli to the blood capillary and carbon dioxide diffuses from the capillary to the alveoli and you breath it out of your body.
Which two gases are exchanged in the aveoli?
At the aveoli, the blood transfers CO2 and the hemoglobin on red blood cells picks up 02.
What gases are exchanged in the repitory ystem?
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
