In alveolar capillaries, the oncotic pressure is greater than the blood pressure (hydrostatic). The oncotic pressure is colloid osmotic pressure exerted mainly by serum albumin: it is about 25 mmHg, while the capillary blood pressure ( hydrostatic pressure) is about 13 mm Hg. This situation, of course, favors reabsorption of fluid into the capillaries.
