3. Red Blood Cells
Red blood cells are by far the most numerous type of blood cell in our bodies. Indeed, our blood is red because of the high number of red blood cells present which, as their name suggests, are also red. They perform a different role to the other cells mentioned, but one that is still extremely important to us.
Red blood cells have the task of transporting oxygen to other cells that make up the various tissues in our body. This is essential because our body’s cells need oxygen in order to metabolize, giving us energy. If we did not have enough red blood cells then our body will essentially suffocate, and we would die.
