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.
The circulatory system delivers blood to many organ systems, including : the nervous system (brain, etc.), the muscular system ( biceps, triceps, etc.), the respiratory system (lungs, alveoli, etc.), the digestive system ( stomach, intestines, etc.) and even to the circulatory system itself.
