NOTHING
it is when we breath out carbon dioxide and plants absorb it and use it to make food then we get oxygen and give out carbon dioxide that is how it goes
the oxygen releases carbon dioxide
During photosynthesis, carbon dioxide and oxygen are exchanged. The plant uses the carbon dioxide for the photosynthesis and expels oxygen.
stuff happens
oxygen and carbon dioxide are exchanged in alveoli (singular alveolus).
Alveolus
It is carbon dioxide which is collected from different organs of the body by blood
alveolus
The process in which oxygen enters the bloodstream through the alveolus and carbon dioxide exits the bloodstream also through the same alveolus to be exhaled.
When carbon monoxide reacts with oxygen carbon dioxide is formed
Alveoli (plural) and alveolus (singular)
Carbon dioxide, CO2
Plants use the carbon dioxide to make food.
NOTHING
One alveolus is a singular, tiny air sac of the lung, surrounded by a network of capillaries, and through which oxygen and carbon dioxide are exchanged. A cluster of such air sacs are alveoli (plural of alveolus).
Both oxygen and carbon dioxide cross the thin lining of the alveolus. Oxygen crosses from inside the lung into the blood and carbon dioxide crosses from the blood into the lung to be exhaled.
