Abstract
In the upright position, ventilation and perfusion both increase from the top to the bottom of the lung. This was previously attributed to the effect of gravity (the so-called gravitational model), but it is now thought that structural similarities between the pulmonary arteries and bronchioles contribute (see Chapter 15).
