  • The circulatory system is responsible for delivery of oxygen and nutrients to the tissue in the organs. All cells in the body require oxygen for cellular reactions. This oxygen, along with the biomolecules from the foods we eat, are used to produce energy. The heart is also a part of this system. The heart is responsible for retrieving deoxygenated blood, pumping it to the lungs and then sending it through the arteries throughout the body.
