Question

For each of the following situations, describe the anticipated effect on blood pressure and the physiological basis of the response:________. (1) a high-salt diet, (2) a blow on the head that damages (disables) the vasomotor center, (3) an attack by a mugger, (4) a hypothalamic tumor resulting in excess ADH production.

Answer 1

Answer: 1) high salt diet increases blood pressure 2) increases blood pressure 3)mugger increases blood pressure 4) increase blood pressure

Explanation: 1)high salt diet increases sodium in blood making it difficult for kidneys to excrete water thus increasing blood volume wm2) damage to vasomotor center means no control of vascular tone thereby increasing blood pressure3) increase blood pressure due to sympathetic nervous system stimulation 4) Excess Adh constrict blood vessels thereby increasing blood pressure
