Circulatory System. This system is made up of the heart, blood, blood vessels, and lymphatics. It is the bodyâs delivery system, concerned with circulating blood to deliver oxygen and nutrients to every part of the body.
Another system that has connection to the circulatory is the urinary system(excretory). This happens in the kidneys. Blood from your heart goes to the kidneys through the aorta. The kidneys filter the blood and then sends it back to the heart in a vein called the vena cava.
