An air bubble could travel to the heart - preventing it from functioning properly... resulting in a fatal heart attack.
Oxygen enters the blood stream through the air sacs in you lungs.
In air breathing animals, oxygen enters the blood stream through the alveoli, tiny sacs in the lungs. In water breathing animals oxygen enters the blood stream through the gills.
after the oxygen from the air enters the lungs,the oxygen gets sent to the heart and then travels through the arteries with the blood.
Pollution enters the system by respiration. When you breathe in your body uses the oxygen in the "air". But when pollution is in the "air", your body takes that in and enters the Ovules of the lung and enter your blood stream.
Oxygen is absorbed in the blood stream primarily in the lungs through the process of diffusion. When we breathe in, oxygen from the air enters the lungs and diffuses across the alveoli into the capillaries, where it binds to hemoglobin in red blood cells and is transported throughout the body.
