Question

While alpha-1 receptors mediate ___________, beta-2 receptors mediate vasodilation in the muscle and liver to aid in the fight or flight response.

Answer 1

Alpha-1 receptors mediate vasoconstriction, while beta-2 receptors mediate vasodilation in the muscle and liver during the fight or flight response.

Step-by-step explanation:

While alpha-1 receptors mediate vasoconstriction, beta-2 receptors mediate vasodilation in the muscle and liver to aid in the fight or flight response. Alpha-1 receptors cause smooth muscle contraction and vasoconstriction in many blood vessels including those of the skin, gastrointestinal system, and kidneys. On the other hand, beta-2 receptors increase intracellular CAMP activity, resulting in smooth muscle relaxation and vasodilation.
