After exercising many of you saw an INCREASE in the amplitude of the pulse transducer suggesting vasodilation in the musculature AND an increase in heart rate. Which of the following combinations or regulatory factors explains this curious (but common) combination of physiological responses. Sympathetic NS increases vasodilation and increases heart rate Parasympathetic NS increases vasodilation and increases heart rate Parasympathetic NS increases vasodilation and sympathetic NS increases heart rate Local paracrine factors increase vasodilation and Frank-Starling effect increases heart rate Local paracrine factors increase vasodilation and Sympathetic NS increases heart rate

		Parasympathetic NS increases vasodilation and increases heart rate
		Parasympathetic NS increases vasodilation and sympathetic NS increases heart rate
		Local paracrine factors increase vasodilation and Frank-Starling effect increases heart rate
		Local paracrine factors increase vasodilation and Sympathetic NS increases heart rate
