Question

What are blood cells?

Answer

There is a lot to know about blood cells, but I will just start with the basics. So blood cells combine with the plasma (fluid), and other components (like wastes, nutrients, and hormones) to produce the composition of blood with circulates within our bodies. Blood cells are produced in bone marrow. There are three types of blood cells - red blood cells (Erythrocytes), white blood cells (Leukocytes), and platelets (Thrombocytes). Red blood cells are responsible for transporting gases within the blood, thus allowing surrounding tissues to absorb oxygen, and allowing carbon dioxide to be absorbed by the blood and expired out. White blood cells are part of the immune system and responsible for defending the body against bacteria, viruses and pathogens. Platelets are the ones that help in forming blood clots during injury.
