👉 A pull fluid, also known as a capillary fluid, is a type of fluid found in biological systems that moves through narrow spaces due to surface tension and adhesion forces rather than relying on pressure gradients. This fluid is crucial in various physiological processes, such as the movement of water and nutrients in plant roots through xylem vessels or the transport of proteins and other molecules in animal tissues. In these systems, the fluid is drawn into narrow spaces by the cohesive and adhesive properties of the fluid itself, creating a capillary action that facilitates transport without the need for external pressure. This mechanism is essential for maintaining hydration and nutrient distribution in living organisms.
