Human gas-exchange occurs in the lungs. Once air enters the lungs, diffusion of O2 and CO2 occurs in the alveoli.
In the lungs at the membrane between the alveoli (air sac) and capillaries (tiny blood vessels) surrounding the alveoli.
CO2 exchanged to blood through capillaries and blood to alveoli
alveoli.
Alveoli
Oxygen+glucose = carbon dioxide + water +energy
co2 is produced the as a waste product in your blood stream. when you inhale you red blood cells take up O2 from your lungs and store it in your Hemoglobin which is located in the RBC. Then your RBC travels thru your heart and you to you body delivering o2 to your organs and tissues. Once your Hemoglobin[Hb] releases o2 to the tissue it exchanges it for CO2 which is the byproduct of respiration. now the RBC flows thru your capilaries to you veins and back to the heart where it then goes to the lungs and gets exchanged for O2 and the co2 will now be exhaled out of your body.
When ther is a higher concentration of O2 than CO2, rubisco can bind O2 in place of CO2.
Chloroplasts take up CO2 and give off O2.
Gaseous waste is expelled from the body primarily through respiration. A process called gas exchange takes place in the lungs. With every breath we take, some quantity of the waste gases (like carbon dioxide, or CO2) in our blood is exchanged for oxygen (O2) in the air inspired. Note that anything else in the air that we inhale can be carried across and into the blood.
photosynthesis
O2 and CO2
o2 co2
Gasses are exchanged (CO2 is lost & O2 is gained).
Henry's law
The alveoli sacks have many capillaries and the exchange occurs. O2 from the lungs hits the blood and CO2 is just given off.
oxygen and carbon dioxide
Alveoli are very tiny air sacs found in the lungs where CO2 and O2 are changed.
Oxygen+glucose = carbon dioxide + water +energy
O2 and Co2, but we breathe out the Co2 again + the O2 which is converted in more Co2
