normal tissuelung1.  The pulmonary capillary pressure is low, about 7 mm Hg, in comparison with a considerablyhigher functional capillary pressure in the peripheral tissues of about 17 mm Hg.2.  The interstitial fluid pressure in the lung is slightly more negative than that in the peripheralsubcutaneous tissue. (This has been measured in two ways: by a micropipette inserted into the pulmonary interstitium, giving a value of about -5 mm Hg, and by measuring the absorption pressure of fluid from the alveoli, giving a value of about -8 mm Hg.)3.  The pulmonary capillaries are relatively leak...
