Cardiovascular+System+EP

Cardiovascular System (1) What are the two parts of the cardiovascular system? (2) What are the functions of the cardiovascular system? (3) What are the types of blood vessels? (4) What is the structure and function of these vessels? (5) Why is the heart a double pump? (6) What causes the "lub" and the "dup" of the heart sounds? (7) What keeps the heart beat regular? (8) What does the pulse rate of a person indicate? (9) What accounts for blood flow in the arteries? (10) What accounts for blood flow in the veins?
 * The heart
 * The blood vessels.

 * Generates blood pressure
 * Blood vessels transport blood into the arteries and veins and the capillaries before coming back to the heart.
 * It refreshes blood and tissue fluid
 * The heart and vessels regulate blood flow to how much the body needs.
 * Arteries
 * The Capillaries
 * The veins
 * The arteries determine the blood pressure.
 * The capillaries help blood flow through the arterioles.
 * Veins come from the capillaries that allows blood to flow throughout the whole body.
 * Because the right ventricle of the heart sends blood through the lungs and the left ventricle sends blood throughout the whole body.
 * The lub sound happens when increasing pressure of blood inside a ventricle forces the cusps of the AV valve to shut.
 * The dub occurs when the ventricles relax.
 * BY keeping the normal blood pressure and when it enters through the capillaries.
 * It indicates the heart rate.
 * The pulmonary circuit.
