Blood flow through the body
Types of blood type vessels
Arteries transport the oxygenated blood away from the left side of the heart.
Veins transport used blood from all over the body back to the heart and lungs for re-oxygenation.
Capillaries are minute blood vessels that join onto the arterioles.
Blood cell formation
Blood cell formation, also called Hematopoiesis, or Hemopoiesis,
red blood cell ,continuous process by which the cellular constituents of blood are replenished as needed. Blood cells are divided into three groups: the red blood cells erythrocytes, the white blood cells leukocytes, and the blood platelets (thrombocytes).
