Previous physiological studies suggest that avian pulmonary capillaries behave like almost rigid tubes. We made morphometric measurements to determine the diameter of the capillaries in chicken lungs when the transmural pressure was altered over a wide range. The diameter of avian pulmonary capillaries increased by only 13% when the pressure inside them was raised from 0 to 25 cmH(2)O. In contrast, other studies have shown that the mean width of the pulmonary capillaries in dogs increased by… CONTINUE READING
