If blood pressure falls then the body does what?

If blood pressure falls, the body initiates compensatory mechanisms to restore it to normal levels. The sympathetic nervous system is activated, leading to an increase in heart rate and constriction of blood vessels. Additionally, the kidneys may release renin, which helps produce angiotensin II, a hormone that further constricts blood vessels and stimulates the release of aldosterone to retain sodium and water. These responses work together to elevate blood pressure back to a healthy range.
