Vedclass · Answer

(C) The parasympathetic nervous system is responsible for lowering or maintaining blood pressure by slowing down the heart rate and promoting vasodilation.Adrenaline increases heart rate and cardiac output,leading to an increase in blood pressure.Angiotensin $II$ is a potent vasoconstrictor that increases blood pressure.The vagus nerve is a major component of the parasympathetic nervous system; its stimulation decreases heart rate and blood pressure.Therefore,both stimulation of parasympathetic nerves and stimulation of the vagus nerve lead to a decrease in blood pressure,making them the correct exceptions.
