i don't know i didn't figure it out
Oxygen exchanges with CO2 (Carbon dioxide) to "purify" blood. This takes place in the aveoli (in the lungs) the blood is transported via blood vessels. Kidneys also purify blood
Carbon dioxide does.
The body system that exchanges o2 and co2 between blood and air is called the respiratory system. It is composed of the nose, windpipe, and lungs. It;s in the lungs that the exchange takes place.
oxygen and co2
The gas we inhale is oxygen. Oxygen is transported from the alveoli in the lungs to the blood cells in the veins and then, distributed to different organs. Thus, resulting deoxygenated blood to produce waste products. So, we exhale carbon dioxide. inhale- oxygen (O2) exhale- carbon dioxide (CO2)
they enter the lungs in order to obtain oxygen and get rid of carbon dioxide. this process occurs in the alveolus of the lungs by diffusion.
Same blood as everywhere else. The difference is the gases in the blood: it enters the lungs low on oxygen and high in CO2, it leaves high in oxygen and low in CO2.
The respiratory
Deoxyganated blood means blood that doesn't have oxygen.
The blood changes from low CO2 to high CO2 in the tissues where oxygen is delivered and CO2 is produced as a byproduct of cellular metabolism.
the respiratory system
well, the process where blood exchanges oxygen for carbon dioxide is called gas exchange system also called delivery system. That's what I know, and i hope it's true.
