I believe it might be HEMOGLOBIN.
The blood leaving the lungs is loaded with oxygen, while blood entering the lungs is about to get oxygen from the respiratory system.
Blood goes to the lungs oxygen poor and comes out of the lungs oxygen rich.
blood takes oxygen and gives carbon dioxide to the lungs
The oxygen poor blood (not enough oxygen) goes to the lungs to get more oxygen to turn into oxygen rich blood (has plenty of oxygen)
no you have oxygen high blood.
Oxygen Poor blood. The lungs add the oxygen to the blood and then release the carbon dioxide.
Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
The blood carries carbon dioxide back to the lungs and oxygen out of it
The blood gets oxygen from the lungs during the process of respiration. Oxygen is inhaled into the lungs, where it diffuses into the bloodstream via tiny air sacs called alveoli. This oxygenated blood is then pumped by the heart to the rest of the body.
As blood moves through the lungs, oxygen is exchanged for carbon dioxide. Oxygen diffuses from the air in the lungs into the blood, increasing the oxygen level in the blood. Conversely, carbon dioxide diffuses from the blood into the air in the lungs, decreasing the carbon dioxide level in the blood.
the blood absorb oxygen in the lungs(cappilaries)
Blood picks up oxygen from the lungs.
