The cardiovascular system has three main functions: transport of oxygen, carbon dioxide and nutrients Describe the components and functions of the . During pulmonary circulation, blood rich in oxygen is pumped into the left atrium of the heart from the lungs, whereas blood low in oxygen exits the heart through the right ventricle to the lung. Respiratory System: The circulatory system and respiratory system make respiration … These roadways travel in one direction only, to keep things going where they should. The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism. Cardiovascular System Components of the Cardiovascular System • ... (SR), functions as the excitation- contraction coupler in cardiac muscle, as in skeletal muscle, by combining with troponin. Arteries carry blood away from the heart and veins carry blood back to the heart. The heart has two ventricles and two atria. The circulatory system transports blood throughout the body. The cardiovascular system or circulatory system is a system which moves nutrients, gases and wastes between cells, helps fight diseases, and transports blood throughout the body (Circulatory System). In simple terms, the primary function of the cardiovascular system is to carry substances vital to life to cells and tissues and to transport waste products from cells and tissues to sites of elimination from the body. Your circulatory system is made up of three parts: the heart, blood vessels and the blood itself. The cardiovascular system is crucial in many other ways, not just in moving oxygen and blood around. Together, your heart and blood vessels make up your cardiovascular system, which circulates blood and oxygen around your body. The air breathed in and held in the lungs is transferred to the blood.
