Oxygen and carbon dioxide are exchanged in the lungs by different means. Carbon dioxide is dissolved in the blood stream as carbonic acid (CO2 + H2O --> H2CO3) and is important in maintaining our pH, or acid-base balance, at 7.4. Excess carbonic acid is turned back to carbon dioxide in the lungs due to diffussion and exhaled.
Oxygen is actively absorbed by the hemoglobin of the red blood cells, attaching to an iron ion at the heart of the hemoglobin protein. Oxygen does not significantly dissolve in the blood stream.
What else can I help you with?
Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
What gasses are exchanged in the lungs?
There are two main gasses that are exchanged in the lungs: carbon dioxide and oxygen. The lungs use tiny air chambers called alveoli to take in oxygen and let out carbon dioxide.
Which two gases are exchanged in the lungs?
oxygen and carbon dioxide
What two gases are exchanged in the lungs?
Oxygen and carbon dioxide in the alceoliCO2 and O2
What gases are exchanged in the lungs during breathing?
Oxygen and carbon dioxide are the gases exchanged in the lungs during breathing.
Which 2 gases are exchanged at the surface of the air sac?
Oxygen and carbon dioxide are exchanged at the surface of the air sac. Oxygen is taken in from the air into the bloodstream, while carbon dioxide is released from the bloodstream into the air to be exhaled.
What gases are exchanged in lungs during breathing?
Oxygen and carbon dioxide are the gases exchanged in the lungs during breathing.
What is the aveloli in the lungs a site of?
These are tiny pockets in the lungs where oxygen and carbon dioxide are exchanged.
In the circulatory system where are most oxygen and carbon dioxide are exchanged?
lungs
Where is carbon dioxide and oxygen exchanged in body?
Carbon dioxide and oxygen are exchanged in the lungs during the process of respiration. Oxygen from the air we breathe diffuses into the blood in the lungs, while carbon dioxide from the blood diffuses into the air we exhale. This exchange occurs in the alveoli, which are small air sacs in the lungs.
What's the process where gases are exchanged in the lungs?
Its called respiration. Oxygen is exchanged for carbon dioxide.
Is respiration a gas exchange?
Yes. Carbon dioxide is exchanged for oxygen in the lungs.
