How the circulatory system works for the human anatomy is the circulatory system delivers the nutrients and oxygen needed to cells to the body. Arties are what carry blood away from the heart and veins carry it back, Makes a circle why it's called the (circulatory system.) There is a main artery and large arteries these lead to small vessels these are what help blood flow. That is why it is not good when one gets plugged because that is when a heart attack happens. The animal I choose was the chameleon there circulatory system is the same and different in some ways. Some of the ways they are different is because a Chameleon is cold blooded it is low in red blood cells they do not need require oxygen to heat to like the human circulatory system
