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.
This helps them hold on to the oxygen too. These red cells pass through the tiny blood vessels in your lungs where the gas exchange takes place in the alveoli (like little bits of broccoli) over a large surface area. Carbon dioxide is expelled, and oxygen bonds to the iron in the red cells.The oxygenated blood then travels around the body to the cells, where it passes into individual cells using a process called osmosis.hese red cells pass through the tiny blood vessels in your lungs where the gas exchange takes place in the alveoli (like little bits of broccoli) over a large surface area.
