Haemoglobin and blood images
Explore images relating to oxygen transport and blood clotting in this gallery
Blood contains several proteins that are vital to the normal functioning of the body. One important role of the blood is to transport substances such as oxygen from the lungs to other tissues in the body. Red blood cells contain a globular protein called haemoglobin, which allows blood to carry 70 times as much oxygen as blood plasma alone. When blood vessels become damaged, blood needs to clot to prevent the affected organism from bleeding to death. Proteins in the blood, such as fibrinogen, are vital for normal clotting.
