Colloid osmotic pressure helps maintain fluid inside blood vessels by opposing hydrostatic pressure
Colloid osmotic pressure acts as an oncotic force that helps retain fluid within blood vessels by counterbalancing capillary hydrostatic pressure, as described by the Starling principle.
The claim is a fundamental physiological principle (part of the Starling equation) supported extensively in the literature where hydrostatic and colloid osmotic pressures interact to govern transvascular fluid exchange.

The classic Starling hypothesis states that opposing hydrostatic and oncotic forces determine fluid flow across the microvascular barrier.
