What is Comparison of the apex of the lung, the base of the lung has and explain in detail?
Overall, perfusion increases more than ventilation at the base of the lung, resulting in lower V/Q ratios in the base of the lung compared to the apex. In a healthy individual, the V/Q ratio is 1 at the middle of the lung, with a minimal spread of V/Q ratios from 0.3 to 2.1 from base to apex Ref: guyton and hall textbook of medical physiology 12 edition page number:332,333,334
