Red Blood Cells and Blood/Air Veins.
red blood cells
Red blood cells give oxygen to the lungs. Also, they carry oxygen out to the body from the heart.

Mostly hemoglobin, which give blood its red color. The red blood cells also help carry oxygen throughout the body.
Hemoglobin is the protein in red blood cells that carries oxygen, giving blood its red color.
Maybe blood cells? :0
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.
Yes, hemoglobin is a protein in red blood cells that binds to oxygen, giving blood its red color. It carries oxygen from the lungs to the rest of the body where it is delivered to cells for energy production.
oxygen
Veins carry dirty blood or blood with carbon di oxide. Arteries carry blood with oxygen to all parts of the body. The veins carrying dirty blood are finally sent to the lungs where they give up the carbon di oxide and take in oxygen for circulation.
In case of human being you have red blood cells in your blood. They contain haemoglobin. This can carry seventy times more oxygen than plasma can carry. ( Say about 280 ml/ 100 ml of blood.) The bonding of oxygen is strong enough to hold the oxygen at lungs and to carry it in blood. Here the oxygen concentration is high. This bonding is loose enough to give oxygen at proximal end of the capillaries. Here oxygen concentration is low. This oxygen is carried through the interstitial fluid to the cells.
Well animals do but plants don't. Plants don't actually really use oxygen- they give it out. They use the sunlight and Carbon Dioxide in photosynthesis and the by-product (what they give out) of this is Oxygen.
