Question

which feedback mechanisms are associated with the chemical control of ventilation during exercise? increases in temperature increases in blood acidity levels lung stretch receptors muscle proprioceptors

Explanation:

Blood acidity levels are related to chemical - control mechanisms in ventilation. During exercise, increased metabolic activity produces more carbon dioxide, which can lower blood pH (increase acidity). This change is detected by chemoreceptors and leads to changes in ventilation. Increases in temperature are a general physiological change not directly a chemical - control feedback for ventilation. Lung stretch receptors are part of the neural control of ventilation (Hering - Breuer reflex). Muscle proprioceptors provide information about muscle movement and position and are part of neural rather than chemical control mechanisms for ventilation.

Answer:

B. Increases in blood acidity levels
