Document Summary
Physiology of the cardiovascular system blood ow, structures. Blood ow through the heart: right atrium > tricuspid valve > right ventricle > pulmonic valve > pulmonary artery > pulmonary vein > left atrium > mitral valve > left ventricle > aortic valve > aorta. 1. the sinoatrial (sa) node res a stimulus across the walls of both left and right atria causing them to contract. Table 51-2: factors related to cardiac output cardiac output (co) - amount of blood elected from the heart each minute; co = sv x. Hr stroke volume (sv) - amount of blood elected from the heart with each beat. Heart rate (hr) - number of beats each minute. Contractility - inotropic state of the myocardium, strength of contraction. Preload - left ventricular end diastolic volume, stretch of the myocardium. Afterload - resistance against which the heart must pump. Factors that influence cardiac output: heart rate preload - degree of stretch of cardiac muscle before contraction.
