Cirulatory System
The Circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. The body's circulatory system really has three distinct parts: pulmonary circulation (lungs),coronary circulation (heart), and systemic circulation( the rest of the system).It also delivers immune cells to fight infections and contains platelets that can form a plug in a damaged blood vessel to prevent blood lossThe muscles around the cheetahs arteries are very muscular so it can pump blood around the body faster. This is important to when a cheetah is running. It runs a real risk of starvings its brain of oxygen so it is important that the oxegen carrying blood gets to the brain quick.
