Question

3. Please explain what is specifically happening in each of the following 4 phases of the cardiac cycle (including any contractions occurring, the direction blood is flowing if it flows at all, and if the valves are open or closed - including specific valve names: a. Ventricular filling phase = b. Isovolumetric contraction phase = c. Ventricular ejection phase = d. Isovolumetric relaxation phase =

Step 1

- The atrioventricular (AV) valves, specifically the tricuspid valve on the right side and the mitral valve on the left side, are open to allow blood to flow into the ventricles. - This phase is also known as diastole. Show more…
