Question

Blood pressure increases with all of the following except increased

A) cardiac output.

B) force of cardiac contraction.

C) parasympathetic innervation.

D) peripheral resistance.

E) blood volume

Answer 1

Blood pressure increases with all of the following except increased parasympathetic innervation. Parasympathetic stimulation of the heart decreases cardiac output and sympathetic stimulation of the peripheral arterioles decreases, causing vasodilation and lowering blood pressure.

Step-by-step explanation:

Blood pressure increases with all of the following except increased parasympathetic innervation. When blood pressure rises too high, the baroreceptors fire at a higher rate and trigger parasympathetic stimulation of the heart, causing cardiac output to decrease. Sympathetic stimulation of the peripheral arterioles will also decrease, resulting in vasodilation which further lowers blood pressure.
