2. White Blood Cells

In addition to red blood cells are white blood cells, also known as leukocytes. These don’t carry hemoglobin but still make up a very important part of the blood because it helps to keep us safe. There are far fewer white blood cells in our blood than red blood cells, which is why the blood remains red. White blood cells are important because they help detect and attack any unwelcome intruders in the body.

If an intruder is found, then white blood cells will swarm to the area to deal with the problem. One weapon that white blood cells have is chemicals that attack intruders, and these chemicals are what make our joints ache when we are ill.
