Blood is a fluid connective tissue composed of a fluid matrix plasma and the blood corpuscles. It splits into two main branches and brings blood from the heart to the lungs. The oxidized copper in the blood protein gives the blood molecules a blue color.

In contrast animals with only one circulatory system such as fish have two-chambered heard. The systemic circulation carries blood from the heart to all the other parts of the body and back again.

It may occur via preexisting vascular redundancy analogous to engineered redundancy as in the circle of Willis in the brain or it may occur via new branches formed between adjacent blood vessels neovascularization as in the eye after a retinal. At the lungs the blood picks up oxygen and drops off carbon dioxide. The circulatory system is further divided into two major circuits a pulmonary circulation and a systemic circulation.
