The Sympathetic Cardiac recording measures sympathetic cardiac nerves. The sympathetic nerves innervate the SA and AV nodes which electrical impulses from these nerves increases activity of the nodes to increase heart rate. The Sympathetic Vasoconstrictor is the recording that measures the electrical activity of sympathetic nervous system nerves. The stimulation of these nerves triggers vasoconstriction of systemic arteries while a decrease in electrical activity in these nerves triggers vasodilatation of systemic arteries.

Activity 2: Effect of Heart Rate | An increase in heart rate will produce the following changes in each of the five other parameters: | Vessel Radius | Drastically increased and then slightly decreased | Blood Viscosity | Remained the same | Systolic Ventricle Volume | Drastically Increased and the slightly decreased | Blood Volume | Remained the same | Venous Capacity | Remained the same | 1. Did mean arterial pressure return to normal? Why or why not? Yes, the mean arterial pressure (MAP) did return to normal. The MAP stabilized at 92.69 after the vessel radius and the systolic ventricle volume decreased. 2. What happened to stroke volume? Peripheral resistance? Blood volume? Explain your answers. The blood volume remained the same without any changes. The stroke volume decreased from 77.20 to 59.48. The peripheral resistance sharply decreased from 1182.00 to 626.31. 3. What happened to the
