The arterial pressure is measured through the large arteries in the systemic circulation. The falling arterial blood pressure promotes vasoconstriction and conserves sodium ions and water.

Thus, it can be concluded that the falling of arterial blood pressure promotes vasoconstriction along with conserve sodium ion and water.
