What are red blood cells?

Answer 1

Red blood cells play an important role in making your body work. First of all, red blood cells do not contain a nucleus, so they are able to carry more oxygen and hemoglobin. Hemoglobin fastens the oxygen molecules to the red blood cells in order to transport oxygen to the cells.

You have three kinds of blood cells in your body. Here are some short-like explanations:

Red blood cells, or erythrocytes, carry oxygen and carbon dioxide round your body. They give your blood its color.

White blood cells, or leukocytes, kill germs, like viruses and bacteria, that get inside your body. They help stop you from getting ill.

Platelets, or thrombocytes, are tiny particle-like cells. They stop the bleeding if you cut yourself.

Answer 2

Red blood cells perform the most important blood duty. A single drop of blood contains millions of red blood cells which are constantly traveling through your body delivering oxygen and removing waste. If they weren't, your body would slowly die.
