From the former writer of "White-Coat."
I'm a third year medical student at the University of Medicine and Health Sciences. I write about what it is you learn going through medical school, and a little of my personal experiences along the way. I'm a cynical, humanist nerd who occasionally writes under the pseudonym of Michael Crichton.
I don't mind answering questions! However, I am no substitute for going and seeing a doctor!
Scanning electron microscope view of lung alveoli, magnified × 750, showing the way in which their shape is retained as their size alters with changes in lung volume. (a) At full capacity (b) At the volume representing the end of a normal expiration. Note that the alveoli are not circular in section but have flat walls, common to adjacent alveoli, with curvatures at the junctions. Compare the capillaries in the stretched alveolar walls in (a) with the rounded capillaries in (b). Adapted from Albertine, K. H., Williams, M. C., and Hyde, D. M. (2000). Fig. 1.22, p. 17.
