Question:
What is the difference between red and white blood cells?


Replies:
One is red and the other white! Oops, sorry, just kidding. Red blood cells have hemoglobin and carry oxygen. In some animals, such as humans, they do not have nuclei. White blood cells are of several types. Some are lymphocytes, which either produce antibodies to attack invaders (B lymphocytes), or attack transplanted tissue (T-lymphocytes). There are also other white blood cells involved in injury response, such as clotting, or in other immune system actions (self-defense). White blood cells do not have hemoglobin, and do have nuclei. They do not carry oxygen.
