There are two main types of circulatory systems:1. Open2. ClosedIn an open circulatory system, blood mixes with internal organs directly. Organisms with this type of system do not have a true heart or capillaries. Instead of a true heart, there are blood vessels that act as pumps to force the blood along. Instead of capillaries, blood vessels join directly with open sinuses.In a closed circulatory system, blood is pumped through a closed system of arteries, veins, and capillaries.(:

The respiratory system helps to bring oxygen into the body through breathing, while the circulatory system, specifically the cardiovascular system, carries the oxygenated blood to the cells through blood vessels.
White blood cells are part of two systems: the circulatory system and the lymphatic system.
Active animals require efficient circulatory systems. These are called closed circulatory systems. Cheetahs have two adaptations of the circulatory system. The first is an enlarged heart and the second is highly muscular arteries.
