As oxygen goes into the red blood cells, it combines with the haemoglobin in it to form oxy-haemoglobin. each haemoglobin combines to 4 molecules of oxygen and because of the absence of a nucleus,more oxygen an be carried. When the red blood cells reach an area of deoxygenated blood, the oxygen from the red blood cells diffuses into the area requiring oxygen while the carbon dioxide moves into the red blood cells. The carbon dioxide then combines with the haemoglobin to form carbinohaemoglobin and is then taken to the lungs where it is unloaded and oxygen is loaded again. This process goes over again and again.
The oxygen depleted blood from the body carrying carbon dioxide enters the lungs from the heart via the veins, in the alveoli the oxygen diffuses across the cell membrane into the arteries and the carbon dioxide diffuses across the cell membrane into the veins and leaves the lungs.
mitochondria. without oxygen, the mitochondria wouldn't be able to live.
When oxygen reaches the bloodstream, it moves into the red blood cells where it binds to hemoglobin. This happens in the alveolar capillaries.

red blood cells
The carrier of food and gases to the body cells is the bloodstream. Oxygen and nutrients are transported by red blood cells, while carbon dioxide and other waste products are carried away from the cells by the bloodstream.
The Lungs
The lungs
blood
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
Human cells obtain the much-needed food and oxygen via the bloodstream.
Oxygen is the gas that usually passes into cells. It moves by diffusion from the bloodstream.
The lungs absorb oxygen (O2) and it is carried in hemoglobin through the bloodstream to various cells.
Through the bloodstream, dissolved in the blood and bound to haemoglobin,
Diffusion, specifically simple diffusion
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
The circulatory system brings oxygen and food to the cells of an organism. It is made up of the heart, a network of vessels and the blood.
red blood cells
The lungs supplies the bloodstream with oxygen. When we breathe in, out lungs fill with oxygen and that oxygen is taken to the heart to keep our body going.
Oxygen is breathed through the nose or mouth and travels to the lungs through the bronchial tubes, then absorbed through the alveoli into the bloodstream. In the bloodstream the oxygen is transported all over the body by red blood cells. So, red blood cells would be your answer.
