Red blood cells (erythrocytes):
carry respiratory gases, mainly oxygen and carbon dioxide.
fight disease and foreign invaders.
aid in blood clotting.
are involved in repairing damaged blood cells.

White blood cells secrete proteins:
known as antibodies, which assist in the immune response.
known as viruses, which assist in the immune response.
known as bacteria, which assist in the immune response.
