Question

multiple choice question
an increase in the force of ventricular contraction caused by sympathetic stimulation will result in increased

afterload
stroke volume
heart rate

Explanation:

Sympathetic stimulation that increases the force of ventricular contraction leads to more blood being ejected per beat. Stroke - volume is the amount of blood ejected by a ventricle in one contraction. An increase in contraction force directly increases stroke - volume. Afterload is the resistance against which the heart pumps, and an increase in ventricular contraction force is not directly equivalent to an increase in afterload. Heart rate is the number of heartbeats per unit time and is not the direct result of increased ventricular contraction force caused by sympathetic stimulation in this context.

Answer:

stroke volume
