Practice: Epinephrine is a hormone that binds to α1 adrenergic receptors on smooth muscle cells in the walls of blood vessels. Binding of epinephrine to α1 receptors activates an intracellular signaling cascade whose end effect is to cause contraction of the smooth muscle and, thus, constriction of the blood vessel. Which of the following is the type of blood vessel that will be most affected by epinephrine?

Which of the following is the type of blood vessel that will be least affected by epinephrine?

Practice: Pregnancy causes a dramatic increase in intraabdominal pressure—the ambient pressure inside the abdomen, pushing from the outside of blood vessels. Which of the following is the type of blood vessel that will be most affected by the increase in intraabdominal pressure caused by pregnancy?
