Capillary action - Wikipedia
Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space in opposition to or at least without the assistance of any external forces like gravity.
7.1: Surface Tension, Viscosity, and Capillary Action
It is partly by capillary action occurring in plant cells called xylem that water and dissolved nutrients are brought from the soil up through the roots and into a plant. Capillary action is the basis for thin layer chromatography, a laboratory technique commonly used to separate small quantities of mixtures.

2020年12月28日 · Capillary function is primarily the transport of blood components into surrounding tissues and the transport of waste products, cells, enzymes, factors, and hormones from tissue to bloodstream. As we have already seen, some molecules can pass through endothelial cell junctions.
Liquid bridging states (a) pendular state, (b) funicular state, (c ...
More detailed saturation levels were introduced in the evaluation of liquid retention capacity measurement, including four states: slurry state, capillary state, funicular state, and pendular...

2023年12月6日 · Capillaries are the smallest blood vessels in the body, connecting the smallest arteries to the smallest veins. They deliver oxygen and nutrients to cells while removing carbon dioxide to be eliminated from the lungs. There are different types of capillaries with specific functions in the body.
Capillary suspensions: Particle networks formed through the capillary …
2014年12月1日 · Capillary suspensions have been divided into two distinct states: the pendular state where the minority liquid preferentially wets the particles; and the capillary state where the secondary fluid wets the particles less well than the primary fluid. Both states are associated with a transition in the suspension from a fluid-like to gel-like ...
Capillary Action and Water | U.S. Geological Survey - USGS.gov
2018年6月5日 · Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work its way all the way up to the branches and leaves. Read on to learn more about how this movement of water takes place.

2011年2月18日 · In the capillary state, we used the hydrophobically modified calcium carbonate (Socal, Solvay Advanced Functional Minerals, Salin de Giraud, France) in DINP or silicone oil as a model system. The transition between the weakly elastic, fluidlike behavior to highly elastic, gel-like behavior can be observed through measurements of the shear ...
Capillary Action - Chemistry LibreTexts
2023年1月30日 · Capillary action can be defined as the ascension of liquids through slim tube, cylinder or permeable substance due to adhesive and cohesive forces interacting between the liquid and the surface. When intermolecular bonding of a liquid itself is substantially inferior to a substances’ surface it is interacting, capillarity occurs.
