Chap 17 Heart Part 2 Pre Reading Docx Guiding Questions Chapter 17 Convey (s) the impulse down the interventricular septum. set (s) the pace for entire heart. electrical link (s) between atria and ventricles. convey (s) the impulse throughout the ventricular walls. which part of the intrinsic conduction system normally initiates the depolarizing impulse that causes a heartbeat?. The heart is a transport system divided into what 2 side by side pumps? 1. right side: receives oxygen poor blood from tissues. pumps to lungs to get rid of co2, pick up o2, via pulmonary circuit. 2. left side: receives oxygenated blood from lungs. pumps to body tissues via systemic circuit.

Heart. the heart is a muscular organ in the chest. it consists mainly of cardiac muscle tissue and pumps blood through blood vessels by repeated, rhythmic contractions. as shown in figure 17.2.3 17.2. 3, the heart has four inner chambers: a right atrium and ventricle and a left atrium and ventricle. Heart sounds: the stethoscope is a clinical device that can be used to listen to, or auscultate, the rhythmic “lub dub” made by the heart sounds (figure 17). there are two heart sounds: (1) , or the “lub,” is heard when the av valves close, and (2) , the “dub,” is heard when the semilunar valves close.
