If by that you mean where they get their own oxygen, then from nowhere because red blood cells do not need oxygen, they perform all reactions anaerobically.
If you mean where they get it to give off for the rest of your body, then its from the lungs.

Oxygen is drawn in through the lungs and diffuses through the pleural membrane into the blood stream where it is picked up by hemoglobin which has four iron molecules in it that allows it to bind to oxygen molecules.

What is the name of the liquid that takes oxygen and gluecose from the blood to other body cells?

Blood.


What carries oxygen around?

In the blood, hemoglobin loosely grabs oxygen for transport to the body cells. The red blood cells (erythrocytes) have the iron (from hemoglobin) that takes the oxygen for a ride.


What blood cell takes oxygen to other cells?

Red Blood Cells carry oxygen to other body cells by using a molecule called hemoglobin. This molecule contains iron which is what oxygen is actually attached to.


What does blood take away from cells?

blood takes the impurities and carbon dioxide from the cells.


What are the functions of hemoglobin?

What type of blood vessel takes blood from cells to the heart?

Arteries carry oxygen-poor blood from the heart; veins carry oxygen-poor blood back to the heart.

What type of blood vessel takes blood cells from back to the heart?

Arteries carry oxygen-poor blood from the heart; veins carry oxygen-poor blood back to the heart.


Is there carbon in our muscles?

It diffuses into capillaries in the muscle where red blood cells and the blood carry it to the lungs were it is released and oxygen takes its place in the blood.


What is the hearts role in maintaining homeostasis?

The heart pumps blood to all of your body. The blood contains oxygen and brings oxygen to all of your cells. The blood also takes carbon dioxide out of your cells and comes out when you exhale. Your cells need oxygen for energy, or cellular respiration. Cellular respiration allows your cells to function normally, maintaining homeostasis. Theorhetically, if the cells could get oxygen by themselves, without the help of blood, we wouldn't need a heart.


What happens in the body cells during repiration?

Respiration is a process of taking in oxygen and giving out of carbondioxide. The oxygen carried by the blood cells transfers oxygen to the tissues and takes up carbondioxide from the tissue.
