The cells that carry oxygen from the lungs to all the parts of your body.

Contain hemoglobin, an iron-containing substance to which oxygen binds.

The reaction between oxygen and the iron in hemoglobin gives blood its bright red color.

Once oxygen has diffused to tissues, blood becomes a dull red.

Cell fragments that play an important role in the blood clotting process.

When you get a cut, platelets stick to the edges of the cut and release proteins called clotting factors.

Clotting factors and other plasma proteins form a net of fibers across the cut.

The fibers trap more platelets and blood cells until a plug forms to seal the cut.

A second blood type is determined by the presence or absence of the Rh factor protein.

About 85% of people are Rh positive.

After an injury, surgery, or some illness, a person may require a blood transfusion.

During a transfusion, blood from a donor is transferred to the patients bloodstream.

Donated blood is tested for blood type and microorganisms, such as those that cause hepatitis or AIDS.

If a patient is given the wrong blood type during a transfusion, the blood will clump together.
