The answe to this question at a primary school level is that the lungs absorb carbon dioxide CO2 from the blood and then feeds oxygen O2 back into the bloody stream
The pulmonary artery is the main artery that carries blood to your lungs.
Alveoli are the tiny air sac structures in the lungs where gas exchange occurs. Their thin walls allow oxygen to pass into the bloodstream and carbon dioxide to be removed. This makes alveoli a critical component of the air-blood barrier, facilitating efficient exchange of gases between the lungs and the blood.
