Quick Answer. Oxygen travels through the human body by being bonded to the iron in a special molecule in blood cells called hemoglobin. This is necessary because, unlike carbon dioxide, oxygen dissolves very poorly in water.
Oxygen from the air to cells. When we breathe in oxygen enters the small air sacs, called alveoli, in the lungs. Oxygen diffuses from there into the bloodstream. Oxygen is not carried in the plasma, but is carried by the red blood cells.These contain a red substance called haemoglobin, which joins onto oxygen and carries it around the body in the blood, then lets it go when necessary.he carbon dioxide produced during respiration diffuses out of the cells and into the blood plasma. The blood carries it to the lungs. It then diffuses across the walls of the alveoli and into the air, ready to be exhaled. 1  Page. 2  1. 3  2. 4  3. 5  4. 6  5.
