A large volume of blood is transfused to a person whose baroreceptor blood pressure control system is not functioning. Arterial
blood pressure rises from the normal level of 100 to 160 mm Hg. If the same volume of blood is infused into the same person when the baroreceptor system is functioning, and this time the arterial pressure increases from the normal level of 100 mm Hg up to 120 mm Hg, what is the gain of the baroreceptor system?
Explanation: Baroreceptors are pressure receptors. The normal set point is 100 nnHg, which means that when the value is 160 mmHg the gain is 60, when the system is running the value is 120 mmHg that is still above 20 mmHg of the normal set point that It is 100 mmHg. Taking every 20 as a unit, the value of 20 above continues to be 40 below 160 when the system did not work, which equals - 2 which is equal to 40 = 2 (20).
