Describe the ventilatory response to incremental (graded) exercise. Include in your discussion: factors that contribute to the rise in ventilation at work rates > 50% VO2max and the location and function of chemoreceptors and mechanoreceptors that contribute to the regulation of breathing. [Hint: Ventilatory Blood-Gas Responses to Exercise – Incremental Exercise and Control of Ventilation]
2. Using proper terminology, discuss the importance of matching blood flow to alveolar ventilation in the lung.
