Physiological System of Heart & Cardiovascular System
Heart § Size - Clenched fist, slightly left § It beats about 4000 times an hour and about 100, 000 times a day § It will beat over 2 billion times in a lifetime § Each heartbeat pumps half cup of blood § The force of your heartbeat is sufficient to shoot blood 30 feet into the air
Heart
CARDIOVASCULAR SYSTEM- THE HEART
CARDIOVASCULAR SYSTEM • It has four valves: ØTricuspid valve or right atrio-ventricular valve ØBicuspid mitral valve or left atrio-ventricular valve ØPulmonary valve or semilunar valve ØAortic valve o All these valves are unidirectional o Provides synchronous operation
CARDIOVASCULAR SYSTEM • 2 types of blood circulation ØPulmonary circulation v. Right ventricle Pulmonary artery Lungs v. Lungs Pulmonary veins Left atrium ØSystemic circulation v. Left atrium Left ventricle Aorta Arteries (Exchange of gases) v. Veins Superior/Inferior venacavae Right atrium Right ventricle
CARDIOVASCULAR SYSTEM - CIRCULATORY SYTEM
Circulation through Heart Although equal volumes of blood are flowing in the pulmonary and systemic circuits, the two ventricles have uneven workloads. Pulmonary Circuit: right, short low pressure circulation. Systemic Circuit: left, long pathway, five times as much resistance to blood flow, high pressure

Heart’s Place in the Circulation Overview of the Cardiovascular System Superior vena cava aorta inferior vena cava
Pulmonary Circulation • • • Pulmonary = Deoxygenated Blood Involves Right Side of Heart Pathway: 1. Superior / Inferior Vena Cava 2. Right Atrium Tricuspid Valve 3. Right Ventricle Pulmonary Semilunar Valve 4. Left Pulmonary Artery 5. Lungs
Systemic Circulation • • • Systemic = Oxygenated Blood Involves Left Side of Heart Pathway: 1. Left Pulmonary Vein 2. Left Atrium Bicuspid Valve 3. Left Ventricle Aortic Semilunar Valve 4. Aorta 5. All Other Tissues
Cardiac Valves [4 main valves] • When the heart is relaxed… – Blood passively fills atrium – Flows right past tricuspid / bicuspid valves – Semilunar Valves remain shut • When the heart contracts (pumps)… – Tricuspid / Bicuspid valves swing up and shut – Blood ejected out of ventricle – Semilunar Valves open up
