During a Cardiovascular Examination,a Patient Has a Resting Heart Rate

During a cardiovascular examination,a patient has a resting heart rate of 65 beats/minute 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/minute,and the 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.
