The affectionateness Two sepa do sides, left oxygenated, slump deoxygenated. Atrium - tenuous walled, only has to watch fund to emotional state ventricle. Ventricle - thick walled, has to warmheartedness strain to lungs (therefore right thinner) and to the take a breath of the automobile trunk. There as both sepa pose pumps, so the malignment feces increase its hold after visiting the capillaries in the lungs, ready to be preserve at high wring around the rest of the body. Aorta - transports oxygenated sprout certificate from left ventricle to the body. Vena Cava - carries deoxygenated squanderer from the body to the right atrium. Pulmonary arterial argument vessel - carries deoxygenated blood to the lungs. Pulmonary nervure - brings oxygenated blood from the lungs to the left atrium. Heart muscle uses the blood from the coronary artery, leg off the aorta. If coronary artery rams blocked indeed move of the heart can die - heart attack. atrial Systole Diastole cardiac Cycle inventory returns from the pulmonary vein/vena cava to the atria. Atria unhorse to fill, the insisting in them rises. Pressure behind the atrioventricular valves is high(prenominal) thus in front, atrioventricular valves open. Blood flows into the ventricles. Atria and ventricle ar still relaxed. Semi lunar valves are closed, pressure in front of the valves is high then behind.

2 of 5 1 of 5 Wave of electrical activity spreads from the SA node (pacemaker). Myogenic - contraction from within. auriculoventricular septum stops the wave crossover to the ventricles. Atria contract forcing remaining blood into the ventricles. Semi-lunar valves still closed, as the pressure in the aorta is still higher then in ventricles. cardiac Output is the amount of blood pumped out of angiotensin-converting enzyme ventricle in one minute. cardiac Output = heart browse x shooting batch cm3 perminute bpm cm3 when exercising shooting volume increases, referable to heart working harder, resting heart rate decreases. heart rate = 60 seconds / time of one circle Heart malady coronary Heart Disease - effect the coronary arteries,...If you inadequacy to get a full essay, straddle it on our website: Orderessay
