Question

Answer 1

The circulatory system is composed of blood, which consist of red blood cells, and even white blood cells. Red blood cells are red when oxygenated and blue when de-oxygenated. You have arteries and veins in the circulatory system. The central location of the circulatory system is located at the heart where oxygen replenishes the de-oxygenated blood cells. The circulator system is quite complex and you should read up on all the details as there is too much to discuss here.
