KROK 1 2016 – Question 119 · KROK (Medicine) · Physiology
When studying the signs of pulmonary ventilation, reduction of forced expiratory volume has been detected. What is the likely cause of this phenomenon?
- A. Increase of pulmonary residual volume
- B. Increase of functional residual lung capacity
- C. Increase of respiratory volume
- D. Obstructive pulmonary disease
- E. Increase of inspiratory reserve volume
Hint
Think about what limits how quickly air can leave the lungs during a forced manoeuvre, and distinguish that from changes in static lung volumes.
