The lungs - clearly, their role is obvious.
The heart, pumps oxygen rich blood around the body.
Red blood cells - they are loaded with Hemoglobin which bonds with the oxygen forming oxyhemoglobin - in English - it turns the oxygen into a weakly bonded solid so the oxygen can flow through the blood stream. red blood cells are a bi-concave disc, Red blood cells are also not an organ but the role they play is super important.
Hope this helps!
