What physiological processes occur in response to an increase in blood pressure? What will be an ideal response?Concepts to Consider: Baroreceptors in the walls of the arteries and heart are sensitive to blood

pressure changes. Increases in blood pressure stretch baroreceptors; message is sent to medulla; cardiac center of brain stimulates parasympathetic nerves that slow the heart down; pressure is lowered. Also, vasomotor center of brain inhibits sympathetic nerves that cause vasodilation, so pressure is lowered
