Which substances are exchanged between the blood in the capillaries and the air in the alveoli?

Oxygen is exchanged from the air in the alveoli into the blood in the capillaries, while carbon dioxide is exchanged from the blood in the capillaries into the air in the alveoli during the process of respiration.


What organ in which the oxygen-carbon dioxide exchange takes place?

The lungs are the organs where the exchange of oxygen and carbon dioxide takes place. This exchange occurs in the alveoli, tiny air sacs within the lungs where oxygen is absorbed into the bloodstream and carbon dioxide is released from the bloodstream.


Which two gases do organisms exchange with their surroundings?

I am not sure but I believe it is carbon diokide and oxygen.


The exchange of oxygen and carbon dioxide occurs where?

In animals: The lungs... they inhale Oxygen, which then passes into the bloodstream, through tiny capillaries in the lung lining.Some blood flowing through the lung lining has excess carbon dioxide, which is passed through to the lungs and exhaled. In plants: carbon dioxide is absorbed through small openings called stomata. During the day photosynthesis uses it in combination with sunlight to produce energy. At night, without sunlight, the process is, sort-of, reversed, and the stomata release carbon-dioxide.


Carbon dioxide enters the blood at the?

Capillaries. The diffusion of nutrients, oxygen, carbon dioxide and wastes take place in the capillaries. If you want to be more specific, it would be the venous ends of the capillaries where carbon dioxide enters the blood.

Where does the exchange of oxygen carbon dioxide in the blood happen?

The exchange of oxygen and carbon dioxide in the blood occurs in the capillaries surrounding the alveoli in the lungs. Oxygen diffuses from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli to be exhaled.

Where does carbon dioxide exchange with oxygen?

Carbon dioxide and oxygen exchange primarily in the lungs during respiration. Oxygen enters the bloodstream from the lungs, while carbon dioxide is removed from the bloodstream and exhaled out of the body. This exchange occurs in the alveoli, small air sacs in the lungs where oxygen from the air is absorbed and carbon dioxide from the blood is released.
