1. CIRCULATORY SYSTEM ORGANS AND FORMATIONS The system that ensures that nutrients from the digestive tract and oxygen from the lungs are delivered to the cells through the rhythmic movements of the heart and that waste materials and carbon dioxide are removed from the cells and sent to the lungs and excretory organs is called the circulatory system (cardiovascular system). This system consists of the heart and blood vessels. The lymphatic system is also included in the circulatory system. The lymphatic system maintains the fluid balance in the body and protects the body against diseases. 1. Structure and Functions of the Heart 2. Location and Adjacence of the Heart 3.
