Acb lecture 32 (10) coronary and pulmonary. If you draw a line from the mid clavicle, down to the 5th intercostal space, can hear sounds. If valve is functioning properly, hear a crisp (cid:498)lub(cid:499) sounds (cid:523)closing of valve(cid:524) If draw oblique line through the heart, can transect most of the valves. Impulse travels from sa node to av (atrioventricular) node too atria contract then the ventricles contract: cant see the node but can define it electrically interventricular wall as the av bundle (bundle of his) It gives branches to these papillary muscles: continues down to apex of heart, within this interventricular septum, av node picks up the signal and will travel past the fibrous skeleton and down the. Collateral circulation: an area supplied by two different blood sources. Coronary artery origins (aorta) (left ventricle: the 3 cusps/leaflets come together at this nodule, these cusps/leaflets have a sinus like a cup flown into the aorta.
