Describe the five reasons breathing rate involuntarily increases during physical activity.
A) Increased oxygen demand, removal of CO₂, stimulation of chemoreceptors, increase in body temperature, activation of sympathetic nervous system
B) Decreased oxygen demand, accumulation of CO₂, inhibition of chemoreceptors, decrease in body temperature, activation of parasympathetic nervous system
C) Increased oxygen demand, accumulation of CO₂, inhibition of chemoreceptors, increase in body temperature, activation of parasympathetic nervous system
D) Decreased oxygen demand, removal of CO₂, stimulation of chemoreceptors, decrease in body temperature, activation of sympathetic nervous system
