Webrelationship between ventricular volumes (x axis) and simultaneous pressures (y axis) during a cardiac cycle. Label a pressure volume loop. A - stretch at end of diastole. B - ventricle encounters afterload. C - end-systolic volume. Effect preload and afterload on pressure volume loop. - blood filling the ventricles during diastole determines ... WebReview each of the pressure line graphs in Focus Figure 18.2. As ventricular pressure decreases below aortic pressure, the aortic semilunar valve closes. In response, blood rebounds against this closed valve, producing a slight increase in the aortic pressure. This is shown on the line graph as the dicrotic notch. dahlia flowers characteristics

WebThe cardiac cycle is a continuous sequence of events that occur in the heart, including both contraction (systole) and relaxation (diastole) of the atria and ventricles. The cycle can be divided into several phases as described below: During this phase, both atria and ventricles are in a relaxed state (diastole). WebThe filling pattern is divided into three phases: a dominant systolic phase, a diastolic phase, and a third short atrial contraction phase with small reversal (upstream) flow from the RA into the systemic veins. During diastole the tricuspid valve opens, and blood from the RA is drained into the RV in two phases, early and late diastolic filling.
