Chapter 20: the cardiovascular system: the heart: atrioventricular (av) valves: the tricuspid and bicuspid valves; located between an atrium and a ventricle. Blood ejected from the right ventricle flows into the pulmonary trunk, which branches into pulmonary arteries that carry blood to the right and left lungs. In pulmonary capillaries, blood unloads co2, which is exhaled, and picks up o2 from inhaled air. The discs contain desmosomes, which hold the fibers together, and gap junctions, which allow muscle action potentials to conduct from one muscle fiber to its neighbors. At rest = 70 ml (page 710) ventricle) into the aorta (or pulmonary trunk) each minute. Calculated by: stroke volume x heart rate. (page 713: frank starling law of the heart: the more the heart fills with blood during diastole, the great the force of contraction during systole. (page 713) lomoar cpsd| 6353920.
