carbon dioxide
Blood is pumped into the lungs and the blood is oxygenated when oxygen is taken into the lungs
When blood is pumped to the lung, carbon dioxide diffuses from the blood into the alveolus. The pumonary artery carries the blood from the heart to the lungs.
blood is pumped through lungs
it is pumped to the heart first then to the lungs
The lungs pull in oxygen which is then taken into the blood stream which is pumped round the body by the heart.
Oxygenated blood is moved from the lungs to the heart. This transport occurs in the pulmonary vein.
When blood is pumped into the thin-walled blood vessels of the lungs, carbon dioxide is replaced with oxygen.
