The Biological Importance of a Red Blood Cell Model

The CAP-e test uses erythrocyte cells. “Erythrocyte” means “red blood cell”. This type of cell is the most abundant in our blood stream. In a healthy person there are more than 100 times more red blood cells than white blood cells.

The red blood cells are best known as transporters of oxygen through our body. However, we are beginning to understand the enormity of other roles these cells play. Whereas the white blood cells provide protection from invading pathogens by immune defence mechanisms, the red blood cells support the life and health of the white blood cells. Of importance to the antioxidant discussion, the red blood cells help to protect the vasculature, tissue, and the other cells in the blood stream from oxidative damage.

Red blood cells are equipped with a series of antioxidants and enzymes that are key players in protecting the body from oxidative damage. In an average adult, there are 25 trillion red blood cells, and if they were all packed together, their volume is 50% larger than the size of the brain. A huge volume, involved in antioxidant protection throughout the entire body.
