blood flow to the lungs

9 Nov

Not sure I would have stopped to think how truly bizarre this excerpt sounds if Eric hadn’t read it aloud:

The pulmonary capillaries form a dense network in the alveolar wall that makes an exceedingly efficient arrangement for gas exchange.  So rich is this mesh that some physiologists feel that it is misleading to talk of a network of individual capillary segments, and the prefer to regard the capillary bed as a sheet of flowing blood interrupted in places by posts, rather like an underground parking garage.  (John B. West, Respiratory Physiology: The Essentials, page 37)

Oh, yeah, I’m not sure I mentioned that we started Pulmonology on Monday.
