During a cardiovascular examination, a patient has a resting heart rate of 65 beats/min and a blood pressure of 100/70 mm Hg in the supine position

In the upright position at steady state, the patient's heart rate is 74 beats/min and blood pressure is 105/70 mm Hg. One physiological change that occurred in the patient as a result of assuming an upright position is:

A. diminished arteriolar resistance
B. increased venous capacitance
C. increased capillary filtration
D. increased cardiac vagal tone
E. increased cardiac sympathetic tone
