Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH). Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.
Jurin's law, or capillary rise, is the simplest analysis of capillary action—the induced motion of liquids in small channels [1] —and states that the maximum height of a liquid in a capillary tube is inversely proportional to the tube's diameter.
The dense layer is the deeper layer of the lamina propria. It consists of dense connective tissue with a large amount of fibers. Between the papillary layer and the deeper layers of the lamina propria is a capillary plexus, which provides nutrition for the all layers of the mucosa and sends capillaries into the connective tissue papillae.

The force with which water is held by capillary action varies with the quantity of water being held. As part of a demonstration conducted by Bright Idea and Webb development: Water entering a natural void, such as a pore within a synthetic mesh material, forms a film on the surface of the material surrounding the pore. The adhesion of the water ...
Individual capillaries are part of the capillary bed, an interweaving network of capillaries supplying tissues and organs. The more metabolically active a tissue is, the more capillaries are required to supply nutrients and carry away products of metabolism.
Surface tension is responsible for a range of other phenomena as well, including surface waves, capillary action, wetting, and ripples. In liquids under nanoscale confinement, surface effects can play a dominating role since – compared with a macroscopic sample of liquid – a much greater fraction of molecules are located near a surface.
Capillary length, a characteristic length scale in fluid mechanics; Capillary action, the drawing of liquid into a tube or porous material; Capillary electrophoresis, the separation of charged species by voltage applied to a small tube; Capillary wave, is a liquid surface wave (ripples), whose dynamics are dominated by the effects of surface ...
The origin of the lesion is unclear. This condition appears to be of an inflammatory nature. [7]An excessive denture palatal relief area, creating a void between the denture base and the tissue of the palate, encourages food entrapment and so encouraging bacterial and fungal growth between the two surfaces.
