WebbHe theorized that the capillaries are semi-permeable - that, due to the pressure, fluid can move freely across the capillary wall to deliver cellular nutrients and remove debris. Starling has been applauded for his brilliance, but he never knew that his theory was missing an important component: the endothelial glycocalyx. Webb28 apr. 2014 · Starling was not aware of the reduction in fluid extravasation by the glycocalyx, which has revised the original Starling equation 2, 8, 11. Three key components of Starling's equation have had to be revised: venous reabsorption; the rate of capillary filtration; and the opposition to capillary filtration.
