Question

looking at the graph from this slide, when is left ventricular pressure the greatest?
ventricular diastole.
ventricular ejection.
isovolumetric contraction.
ventricular filling.

Explanation:

During ventricular ejection, the left ventricle contracts forcefully to pump blood out into the aorta against systemic pressure, resulting in the highest left - ventricular pressure. In ventricular diastole, the ventricle is relaxed and pressure is low. Isovolumetric contraction is the initial phase of contraction before the aortic valve opens, and pressure is rising but not at its peak yet. Ventricular filling occurs when the ventricle is receiving blood and pressure is relatively low.

Answer:

B. Ventricular ejection
