3 Anatomy of the Heart Location = in the center of the lungs, behind the sternum, 2/3 of the heart lies to the left of midline and 1/3 lies to the right of midline Base of heart (top) = 2 nd intercostal space Apex of heart (bottom) = 5 th intercostal space, midclavicular line (*point of maximal impulse is located here) Function = primary function is to circulate blood throughout the body Interior of the heart: Chambers o 2 upper chambers (right atrium and left atrium) = receive incoming blood o 2 lower chambers (right ventricle and left ventricle) = pump blood out of the heart Septa o Interarterial septum = separates the 2 atria o Interventricular septum = separates the 2 ventricles Valves o Atrioventricular valves (AV valves) separate atria from ventricles Tricuspid valve separates R atrium from R ventricle Mitral valve separates L atrium from L ventricle *First heart sound (S1) is due to AV valve closure o Semilunar valves Pulmonic valve separates R ventricle from pulmonary artery Aortic valve separates L ventricle from aorta *Second heart sound (S2) is due to closure of semilunar valves Thickness of chamber walls: Thickness of walls depends on amount of pressure needed during ejection Atria = thin walls Blood collection area; low pressure Right ventricle = thicker than atria, thinner than left ventricle Pumps blood short distance against low pressure Left ventricle = thickest wall Pumps blood longest distance against the highest pressure Prepared exclusively for [email protected] Transaction: 0043620185
