What is vasoconstriction?Multiple choice question.compression of a vein because of skeletal muscle contractionan increase in the diameter of a blood vessela decrease in the diameter of a blood vesselcontraction of the ventricles which increases ventricular pressure

The nervous system can trigger vasoconstriction and vasodilation of arteries. What effect does this have?Multiple choice question.forces nutrients across the vessel wallinfluences blood flow and blood pressureassists with oxygen exchange across the vessel wall

Why does the body need skeletal muscle contraction, pressure changes during breathing, and vasoconstriction to move blood through the veins?Multiple choice question.Veins are so superficial that the force of the heart can't reach them.The blood pressure in the veins is too low to push blood toward the heart.Veins contain valves which partially obstruct blood flow in them.
