Blood contains a protein called hemoglobin. Hemoglobin, which contains iron, is found in red blood cells and is the ingredient that makes blood red. Hemoglobin transports oxygen from the lungs to wherever it's needed throughout your body. You've probably noticed that sometimes blood is bright red, while other times it is dark red. The difference in color comes from the changing amounts of oxygen in the blood. Arteries, a type of blood vessel, carry blood away from the lungs and heart to the rest of your body. That blood is rich in oxygen, which joins with hemoglobin to give the blood its bright red color. Tiny blood vessels called capillaries, which have narrow walls through which tiny substances can pass, distribute oxygen and nutrients to all of your body's cells.
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.
It is the lungs. it is there it is simple. when one breathes you inhale oxygen when you exhale you exhale carbon dioxide
Evergreen trees do give off oxygen. They give off less oxygen than deciduous trees do in the summer, but they do release oxygen all year.
The pathway of the circulatory system varies based on different species. The mammalian cardiovascular system begins with the pulmonary circuit. The right ventricle pumps blood to the lungs via the pulmonary arteries. As the blood flows through capillary beds in the lungs, it adds oxygen and subtracts carbon dioxide. Oxygen-rich blood comes from the lungs via the pulmonary veins to the left atrium of the heart. Next the oxygen-rich blood flows into the left ventricle as the ventricle opens and the atrium closes. The left ventricle pumps the oxygen-rich blood out of the body tissues through the systemic circuit. Blood leaves the left ventricle through the aorta, which passes blood to arteries leading throughout the body. The first branches from the aorta are the coronary arteries which provide blood that the heart muscle needs. Then come branches leading to capillary beds in the forelimbs. The aorta continues, supplying oxygen-rich blood to arteries leading to arterioles and capillary beds in the abdominal organs and legs. Inside the capillaries, oxygen and carbon dioxide diffuse along their concentration gradients with oxygen being moved from the blood to the tissues. Carbon dioxide produced by cellular respiration diffuses into the bloodstream. Capillaries join again, forming venules, which give blood to veins. Oxygen-poor blood from the head, neck, and forelimbs is guided into a large vein called the anterior vena cava. Another large vein called the posterior vena cava drains blood from the chest and back legs. The two venae cavae empty their blood into the right atrium and the oxygen-poor blood flows into the right ventricle.
Maybe blood cells? :0
It gives up oxygen, and carries out carbon dioxide.
Proteins don't give blood its color, the great amount of red blood cells do. Hence the name, they are red and give blood its color.
It gives up oxygen, and carries out carbon dioxide.
red blood cells
Red Blood Cells and Blood/Air Veins.
The simplest answer is "arteries," which generally carry oxygen-rich blood from the heart to the body, but the pulmonary veins also carry oxygen-rich blood. The lungs have oxygen that gives oxygen to the cells. Our body is a closed system so the blood never leaves the body system unless we are cut. After the blood has used up all of the oxygen it has the blood is recirculated through the heart and lungs once more! Thus this process goes on and on! An ARTERY carries oxygen rich or oxygenated blood from the heart to the body cells to give oxygen to them. I remember this by: Artery Away Arteries carry oxygen rich blood from the lungs to other parts of the body. Veins return oxygen poor blood to the heart where it gets recirculated through the lungs and then throughout the body again. The arteries.
Mostly hemoglobin, which give blood its red color. The red blood cells also help carry oxygen throughout the body.
iron. the blood contains iron and when you breathe, you give oxygen to it. so your blood is red pretty much because of oxidized iron. the red blood cells take the oxygen through the body and when it is deposited the blood turns blue, that's why the veins in your wrist are blue.

Red blood cells give oxygen to the lungs. Also, they carry oxygen out to the body from the heart.
