How can control of sympathetic nerves to arterioles achieve vasodilation?
Step by step
Solved in 2 steps
- Why would blocking the action of a vasoconstriction lower blood pressure?Distinguish between the effects of vasodilation andvasoconstriction on blood flowAccording to Poiseuille's Law, vasodilation is associated with increased blood flow. Knowing that capillaries cannot change diameter but arterioles can, how do your observations support this?
- What is a pressure gradient? Where are the pressure gradients present in the vasculature? Give examples how changes in pressure affect circulation.What effect would the vasoconstriction of the renal artery have on blood pressure and blood volume?how do vasodilation and vasoconstriction help the body to regulate circulation dynamics?
- Predict the effect of each of the following conditions on blood flow:(a) vasoconstriction of blood vessels in the skin in response to coldexposure, (b) vasodilation of blood vessels in the skin in response toelevated body temperature, and (c) erythrocytosis, which results in agreatly increased hematocrit.How does vasoconstriction help increase the coretemperature of the body?Which of the following is true regarding plasma colloid osmotic pressure ? 1) It is less than interstitial osmotic pressure 2) It decreases by significantly in the muscle capillaries as blood flows from the arteriole end to the venous end 3) It is primarily caused by the presence of the substances in the plasma such as sodium and potassium 4) It increases in response to an increase in plasma fibrinogen concentration asap please
