Red Blood Cells

Say: red blud sels

Red blood cells have the important job of carrying oxygen. These cells, which float in your blood, begin their journey in the lungs, where they pick up oxygen from the air you breathe. Then they travel to the heart, which pumps out the blood, delivering oxygen to all parts of your body.
