This system is my fav because without this you would not be
alive. This system includes the heart,blood and blood vessels, lymph, lymphatic
vessels, lymph glands. The process is based on involved in circulating blood
and lymph through the body.
The circulatory
system is the delivery of oxygen, nutrient molecules, and hormones and the
removal of carbon dioxide, ammonia and other metabolic wastes. Capillaries are
the points of exchange between the blood and surrounding tissues.
