Question

Which of the following statements about exercise and respiration is(are) false?

a) Feedforward mechanisms help to increase ventilation in preparation for exercise.
b) Negative feedback mechanisms help prevent hyperventilation.
c) The increased ventilation during exercise is referred to as ""exercise apnea.""
d) Minute ventilation is controlled by both humoral and neurogenic mechanisms.
e) Answers a and c are false.
f) None of the above are false.

Answer 1

The false statements are that feedforward mechanisms help to increase ventilation in preparation for exercise, and the term 'exercise apnea' is incorrect; the correct term is hyperpnea.

Step-by-step explanation:

The question pertains to the mechanisms of respiratory function changes during exercise. The false statements among the ones provided about exercise and respiration are: a) Feedforward mechanisms help to increase ventilation in preparation for exercise, and c) The increased ventilation during exercise is referred to as "exercise apnea." The correct term for increased ventilation related to exercise is hyperpnea, not exercise apnea. Feedforward mechanisms do indeed help prepare the body's respiratory system before the oxygen demand rises. Negative feedback mechanisms work to prevent excessive ventilation or hyperventilation. Minute ventilation is indeed controlled by a combination of chemical and neural factors, which are humoral and neurogenic mechanisms, respectively.
