It sure would be nice if the introductory paragraph was more understandable by the average reader. The notion of hydrostatic versus osmotic pressure from blood plasma is not commonly understood. It also does not really tell the reader much even if he goes and reads the hyperlinked articles. What would be helpful is understanding the meaning and implication of the Starling equation in lay terms.

The article does not seem to be consistent. See the following excerpts:
"Note that previously it was believed that at steady state the arterial capillaries filter fluid and the venous capillaries reabsorb it, as shown by the diagram. Though many physiology textbooks still use this misconception, modern evidence shows that in most cases venular blood pressure exceeds the opposing pressure, thus maintaining a positive outward force. This indicates that capillaries are normally in a state of filtration along their entire length."
"In the beginning (arteriolar end) of a capillary, there is a net driving force ( ) outwards from the capillary of +9 mmHg. In the end (venular end), on the other hand, there is a net driving force of −8 mmHg." — Preceding unsigned comment added by 22.214.171.124 (talk) 00:48, 28 October 2012 (UTC)
Seeing as how much of this article is sourced from Boron, somebody should really add in the more complex and more complete model given in it - aka the one which utilises hydrostatic and oncotic pressures from the subglycocalyx. I don't fully understand it myself. 126.96.36.199 (talk) 10:35, 29 August 2013 (UTC)
The article should describe the units of each of the variables. Analysis of the units makes it much clearer that the capillary is a filter, and that flow is driven by a pressure gradient working against a resistive boundary.
