Name the parts of the cardiovascular system and state their functions.
What will be an ideal response?
Answers will vary. The cardiovascular system consists of the heart, the blood vessels, and the blood. It transports vital substances throughout the body. These substances include nutrients, waste products, oxygen, carbon dioxide, minerals, hormones, drugs, and body heat. The blood plays an important role in the body's defense against disease. The four chambers of the heart are divided into two chambers on the right side and two chambers on the left side. The contractions of the chambers increase the pressure within the ventricles, which forces the blood through a system of valves and out into the general circulation. The three main types of vessels are the arteries, veins, and capillaries. Arteries carry blood away from the heart. Veins travel toward the heart and, except for the pulmonary vein, carry deoxygenated blood. The capillaries serve the important function of carrying oxygen and other nutrients to the tissues and taking away the waste products.
