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.
Deoxyganated blood means blood that doesn't have oxygen.
The respiratory
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.
CO2 does not block the transport of oxygen by hemoglobin; rather, it influences it. Hemoglobin binds to oxygen in the lungs and releases it in tissues where CO2 levels are higher. The presence of CO2 in the blood promotes the formation of carbonic acid, which lowers blood pH and causes hemoglobin to release more oxygen, a phenomenon known as the Bohr effect. Thus, while CO2 and oxygen compete for binding sites, CO2 actually enhances oxygen delivery to tissues by facilitating its release from hemoglobin.
