2 primary cusps of Left A V valve hint mitral anterior and posterior cusps 3 leaflets of tricuspid valve Anterior Septal Posterior 3 cusps of the pulmonary valve anterior right and left cusps after blood goes through the pulmonary valve it goes to the pulmonary trunk Aortic sinuses opening for left and right coronary arteries Apex base of heart shifted to the left the heart takes up a large portion of the center of your chest left shifting results in a dent in the left lung Ascending Aorta moves into descending aorta Elastic v distributive arteries Aortic arch Left subclavian and left common carotid Right brachiocephalic trunk to right subclavian and right common carotid atria upper chambers of heart holding chambers Cardiovascular system Chordae tendineae Endocardium permits blood circulation throughout the body cord like tendons that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart what makes up the inner chambers of the heart between myocardium and heart chambers Epicardium Great Vessels visceral pericardium sits against heart muscle itself Superior Vena Cava goes into right atrium Inferior Vena Cava Pulmonary Trunk Pulmonary Veins Ascending Aorta inter ventricular septum divides the right and left ventricles Know order of blood flow into right atrium to right ventricle to trunk to pulmonary arteries to pulmonary veins then to left ventricle then to ascending aorta KNOW THE DIAGRAM ON SLIDE 14 Left and right coronary arteries provide blood flow to heart Left heart contains Left vs Right heart Left atrium A V orfice Left A V valve mitral bicuspid right pulmonary circulation getting blood to lungs left systemic circulation depositing blood everywhere else systemic circulation Mediastinum Anterior Posterior Superior Myocardium Actual heart muscle itself Papillary muscles muscles located in ventricles that prevent the prolapse of the valves attach to chordae tendineae and each of the tricuspid valves Path of left heart left ventricle aortic valve aortic sinuses Pericardium Outer layer that surrounds the heart Right atrium the right heart contains superior and inferior vena cava holding chamber right ventricle pulmonary valve pulmonary trunk tricuspid valve A V orifice papillary muscles chordae tendineae Serous space to create a frictionless environment thickness of muscular walls larger muscles have to do more work the left will be bigger because it has to pump blood to the entire body Tricuspid valve separates atrium form ventricles prevents backflow of blood into right atrium Ventricles pumping chambers with the arteries we only have a right brachiocephalic vein
