Questions: Autonomic Nervous System (ANS) Physiology, Part A: Control of Heart Rate The autonomic nervous system regulates involuntary body functions, including heart rate. As sympathetic and parasympathetic inputs to the heart change, heart rate adjusts accordingly. In this experiment, you will observe how heart rate changes in response to various physiological challenges. Product A Product B Product C Base HR 70 beats/min 70 beats/min 70 beats/min 1.0 min 2 beats 4 beats 8 beats 2.0 min 4 beats 8 beats 16 beats 3.0 min 6 beats 16 beats 24 beats 4.0 min 8 beats 20 beats 32 beats Using the data above, complete the following: 1. For each product, calculate the change in heart rate (ΔHR) from baseline at each time point. 2. Graph ΔHR vs. time for all three products on the same set of axes. 3. Based on your graph, which product caused the greatest increase in heart rate? The least? Multiple Choice: Which of the following statements about the autonomic control of heart rate is correct? - The sympathetic nervous system increases heart rate - The parasympathetic nervous system increases heart rate - Norepinephrine is the neurotransmitter for the parasympathetic nervous system - Acetylcholine is the neurotransmitter for the sympathetic nervous system
