Answer 1

Answer:- Blood pressure will decrease after standing up from a prone position.

Explanation:-

Postural Hypotension:-
                 
                  ‎It is defined as a fall in systolic blood pressure of at least 20 mm Hg or diastolic blood pressure of at least 10 mm Hg when a person assumes a standing position.
                ✓ ‎It occurs when a person's blood pressure falls when suddenly standing up from a lying or sitting position.
                  ‎✓ It occurs predominantly by delayed constriction of the lower body blood vessels, which is normally required to maintain an adequate blood pressure when changing position to standing. As a result, blood pools in the blood vessels of the legs for a longer period and less is returned to the heart, thereby leading to a reduced cardiac output.
