Question

19 multiple choice 10 points which of the following is increased when sympathetic stimulation to the heart increases? stroke volume total peripheral resistance end - diastolic volume venous return

Explanation:

When sympathetic stimulation to the heart increases, it causes the heart to contract more forcefully, which increases stroke volume. Sympathetic activation leads to release of neurotransmitters like norepinephrine that act on the heart muscle to enhance contractility. Total peripheral resistance is more related to vasoconstriction in blood vessels not directly to heart - specific sympathetic effects in this context. End - diastolic volume can be affected by factors like venous return and pre - load, and while sympathetic stimulation can have some secondary effects on it through changes in venous tone, its primary effect is not a direct increase in end - diastolic volume. Venous return is influenced by factors such as venous tone and pressure gradients, and sympathetic stimulation has more complex and indirect effects on it compared to the direct effect on stroke volume.

Answer:

Stroke volume
