Surface tension and surface adsorption occur only on the surface of a substance. Surface tension is the tendency of a liquid surface to shrink into the minimum surface area possible, while surface adsorption is the accumulation of molecules at the surface of a material.
Arteriole
These are hydrogen bonds between water molecules.
capillary
surface layer molecules only have attractions downwards and sidewards no upwards attraction is there so the sidewards attraction will acts as a elastic force rusult to surface tension manoj kottakkal
Capillary tubes are renowned for their capillary action on liquids, i.e. they cause liquids to rise up inside them. Capillary tubes are the essence of thermometers that use a liquid indicator. In biology and the plant world, capillary tubes are fundamental to the movement of fluids through the systems of living organisms.
In the rising action of a story, there may be little action as the setting, characters, and conflicts are established. This part of the plot typically involves building tension and introducing the main problem or challenge that the characters will face.
exchage of materials between blood and tissues occur in cappilaries.

As the particle size decreases, capillarity increases. Smaller particles have more surface area for capillary action to occur, allowing liquids to be drawn up higher through the small spaces between particles. This relationship is important for understanding how liquids move through porous materials such as soil or rock.
A meniscus occurs due to the adhesive and cohesive forces between a liquid and a solid surface. The curvature of the meniscus is caused by the differing surface tensions at the interface of the liquid and solid.
