It disintegrates the red blood cells and sets the hemoglobin free, which the liver converts into bilirubin; it gives rise to new red blood cells during fetal life and in the newborn; serves as a reservoir of blood; produces lymphocytes and plasma cells; and has other important functions, the full scope of which hasn't been entirely determined.
