The circulatory system, also known as the body's transport system, consists of the heart, blood, vessels, and lymphatic system. Blood carries oxygen, nutrients to cells and removes carbon dioxide and other wastes. There are two types of circulatory systems - open systems where blood leaves vessels and bathes organs directly, and closed systems where blood remains inside vessels and flows from arteries to veins through capillaries. Most vertebrates including humans have a closed circulatory system.

5. Open Circulatory Systems
-blood is pumped from the heart through blood
vessels but then it leaves the blood vessels and enters
body cavities, where the organs are bathed in blood, or
sinuses (spaces) within the organs.

6. Open Circulatory Systems

7. Closed Circulatory Systems
-The blood remains inside the blood vessels and
does not come out. The blood flows from arteries
to veins through small blood vessels called
capillaries. The closed type of circulatory system
occurs in most of the Annelids, Cephalopods and
Vertebrates including man.
