      Generally this is the heart, arteries, capillaries and veins. It is a delivery system for our body. Delivering and collecting oxygen and nutrients and helping to collect waste. To be technically correct should also include the lymphatic system which helps to return the fluid and other chemicals that leave the blood in the capillaries to bath the tissues.

      Not much to add, a part from being the lifeline of the body….transporting nutrient, water and oxygen to billions of cells in the body and collecting /carrying away any waste such as carbon dioxide that the cells produce!
