GENERAL HISTOLOGY

Detailed explanation-1: -This upward motion against gravity, known as capillary action, depends on the attraction between water molecules and the glass walls of the tube (adhesion), as well as on interactions between water molecules (cohesion).

Detailed explanation-2: -Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.

Detailed explanation-3: -What is Capillary Action? We can define capillary action as a phenomenon where ascension of liquids through a tube or cylinder takes place. This primarily occurs due to adhesive and cohesive forces. The liquid is drawn upward due to this interaction between the phenomena. Narrower the tube, higher will the liquid rise.

Detailed explanation-4: -Cohesion: Hydrogen Bonds Make Water Sticky In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-5: -For example, capillary actions works when placing a thin or narrow straw into a cup of water, we can see the water goes into the straw; the level the water reaches in the narrow straw is higher than the surrounding water in the cup.
