Lungs.
(or gills for fish).
stores it, and carries it to vital organs and muscles that need it.
The Arteries carry the blood away from the heart to the other organs and the veins bring it back when the blood has no more nutrients. From Unkown
Left side of the heart (left ventricle and atrium) has deoxygenated blood, but after its pumped through the lungs and enters the right side of the heart, the blood is oxygenated. If you divide the circulatory system into 'organs', then veins and venules have less oxygen, while arteries and arterioles have more oxygen. With other organs, there should be indistinguishably equal amounts of oxygenated and deoxygenated blood.
Red blood cells carry oxygen to all areas of the body. Oxygen is vital to all of the body's organs and functions.
The heart gets the oxygen from the red blood cells that "trade" CO2 for oxygen in the lungs and travels back up to the heart and gives the heart a bit of the oxygen and then gives the rest of the oxygen to the other organs (like the alveoli and the liver and the gut ect)
your red blood cells
Oxygen passes from the blood into organs through the wall of capillaries.
supply oxygen to all organs
Blood and oxygen.
oxygen and nutrients
Mainly to carry oxygen to your organs..
Red blood cells carry oxygen from the lungs to all the organs so they can live.
Carry oxygen and nutrients to organs and carbon dioxide and metabolites away from organs
Because adequate blood flow is required to provide the organs and tissues with oxygen, vasculitis causes damage to oxygen-deprived organs and tissues
Arteries carry oxygenated blood from the lungs to the organs. Veins carry blood back from the organs to the lungs so that it can be refilled with oxygen after it was used by the organs.
red blood cells
There are two organs, the lungs and the blood.
