1. Increased ventilation during exercise is primary causedby

- Changes in the pCO2
- Neurogenic stimulus from the cortex
- All of the above
2. Functional Residual Capacity is?
           a. Extra volume of air that can be expelled during a maximalexhalation
           b. The volume of air left in the lungs after normal breath
           c. The minimum volume of air remaining in the lungs even after amaximal expiration
           d. The volume of air in the lungs at the end of a normal passiveexpiration
3. Central Chemoreceptors are sensitive to changes in
           a. pCO2
           b. pO2
           c. Concentration of H+
           d. None of the above
