Histological images of mammalian pulmonary capillaries shown at (A) 24 cm above zone I–II junction in the dog lung, (B) 32 cm below zone II–III junction in the dog lung, (C) 7 cm above zone I–II junction in the cat lung, and (D) 17 cm below zone II–III junction in the cat lung. In A and C the capillaries are collapsed, but in B and D they are clearly patent. Dog images from Glazier et al. (1969); cat images from Vreim et al. (1974).
