An Animation of red blood cells and platelets flowing through an artery. A Lymphocyte or white blood cell (translucent and purple) is seen tumbling past. Red blood cells contain a protein called haemoglobin that carries fresh oxygen throughout the body. These cells also move carbon dioxide to the lungs for it to be exhaled. Platelets are cells that aid in blood clotting. Lymphocytes have an important function in immunity. They recognize antigens (foreign bodies such as viruses), fight them with antibodies, and also have the capability of destroying the body's own cells when necessary to help keep the body healthy. | |
