Solved in 2 steps
- High pressure in the systemic and pulmonary circuit often results in ventricular hypertrophy in which the ventricle enlarges to pump against the greater force. Which side(s) of the heart would affected by high pressure in the pulmonary circuit? Which side(s) of the heart would be affected by high pressure in the systemic circuit? Could you explain this answer? Thank youWhat structures and properties should an artificial heart have?Regarding the cardiac cycle at resting HR, when in the cycle does ventricular filling occur? Howimportant is atrial contraction to the EDV? Why is the first part of ventricular contraction isovolumetric?When and why does rapid ejection of blood from the ventricle occur?
