While jogging, a person has a stroke volume of 130 mL/beat and a heart rate of 120 beats per minute. Their resting stroke volume is 70 mL/beat and resting heart rate is 60 beats per minute. Which answer best describes the effect of jogging on the person's cardiac output?
A) Their cardiac output did not change. Only their respiratory rate changed.
B) During exercise, their cardiac output decreased by 11,400 mL/minute.
C) During rest, their cardiac output increased by 60 mL/beat.
D) Their cardiac output increased from 4,200 mL/minute to 15,600 mL/minute when jogging.

Cardiac output is calculated as stroke volume times heart rate. Resting cardiac output is 70 mL/beat * 60 beats/minute = 4,200 mL/minute. During jogging, it's 130 mL/beat * 120 beats/minute = 15,600 mL/minute, indicating an increase.
