Properties of erythrocytes, leukocytes and platelets.

Red blood cells are red blood cells. They are shaped like a washer in humans. Their function is to carry oxygen from the lungs to all cells in the body. This is due to hemoglobin.
Platelets are essential for blood clotting. When a person or animal is injured, the platelets prevent it from bleeding. They interact with air and the blood stops and does not continue to flow out of the wound.
Leukocytes are protective cells. They protect the body from external threats and attack foreign cells and viruses.
