Systole - Answers -Contraction of the heart
Diastole - Answers -Relaxation of the heart
S1 - Answers -the first heart sound, heard when the atrioventricular (mitral and tricuspid) valves
close at the start of systole.
S2 - Answers -second heart sound, caused by the closure of aortic and pulmonic valves, marking
the end of systole.
valvular stenosis - Answers -a condition in which there is narrowing, stiffening, thickening, or
blockage of one or more valves of the heart impeding the flow of blood and increasing cardiac
workload proximal to the diseased valve. Intraventricular or atrial pressure increases in the
chamber to overcome resistance to flow through the valve. Increased pressure causes the
myocardium to work harder, causing myocardial hypertrophy
Stroke Volume (SV) - Answers -The volume of blood pumped forward with each ventricular
contraction. Determined by: preload, contractility, and afterload.

, Cor Pulmonale - Answers -RHF; Inability of RV to provide adequate blood flow to pulmonary
circulation. Causes: pulmonary disease, RV MI, RV hypertrophy, pulmonary SLV or valve damage
secondary to LHR.
Right Heart Failure physiological process - Answers -High pulmonary vascular pressure >
^RV contraction force (^afterload)>
^RV unable to completely empty>
^RV preload
^RA unable to empty completely>
^RA preload>
^vena cava and systemic venous volume and pressure>
fluid forced out into peripheral tissues>
jugular distention, hepatosplenomegaly, peripheral edema>
L heart failure = biventricular heart failure
Left Heart Failure physiological process - Answers -High systemic vascular pressure >
^LV contraction force (^afterload)>
^LV unable to eject normal amount of blood>
^LV preload
^LA unable to eject normal amount of blood>
^LA preload>
^blood volume and pressure in pulmonary veins>
fluid forced out into pulmonary tissues>
pulmonary edema, dyspnea>
