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.

∙ 8y agoSmall blood vessals pass next to the air sacs in the lungs, and gases are exchanged across a thin membrane. Well we all know we have two lungs well the second lung is maid for transferring the carbon dioxide and switching it into oxygen that's y we need trees to breath in our carbon dioxide and give us our oxygen

Where are oxygen and carbon dioxide exchanged in the lungs?
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
Which 2 gases are exchanged at the surface of the air sac?
During photosynthesis, carbon dioxide and oxygen are exchanged. The plant uses the carbon dioxide for the photosynthesis and expels oxygen.
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.
What two gases are exchanged in the lungs?
Oxygen and carbon dioxide in the alceoliCO2 and O2
Which two gases are exchanged in the lungs?
oxygen and carbon dioxide
What gases are exchanged in the lungs during breathing?
Oxygen and carbon dioxide are the gases exchanged in the lungs during breathing.
The area in the lungs where oxygen and carbon dioxide are exchanged is the?
Alveolus
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
What's the process where gases are exchanged in the lungs?
Its called respiration. Oxygen is exchanged for carbon dioxide.
Circulatory system where oxygen and carbon dioxide are exchanged?
The respiratory system; the lungs.
