Which forces affect the exchange of substances between blood and tissue fluid?
At the proximal end of capillary, you get the fluid out in the tissue fluid due to blood pressure. At the distal end of the capillary, you get back the tissue fluid due to oncotic pressure of the blood proteins.
What is capillary action due to?
The adhesive intermolecular forces between the substance rising (the one experiencing capillary action) and the container (typically a capillary).
What do Cohesion and Adhesion have to do with Capillary action?
The liquid rises up due to the forces of adhesion between the capillary and liquid.. It rises till the extent when adhesive and cohesive forces and external forces balance each other...
Which force supplies the energy for percolation?
gravity and capillary forces
Which forces act to move fluid back into the capillary reabsorption?
Osmotic pressure is what draws fluid back into the capillary from the tissues.
Capillary rise is due to the action of adhesion . is it right or wrong?
If the shape of the meniscus is concave up then the cohesive forces are weaker than the adhesive forces. If the shape of the menicus is concave down then the adhesive forces are weaker than the cohesive forces. So capillary rise is where adhesive forces are stronger.
What forces make possible the movement of plant sap?
capillary action
What is the difference between capillary action and surface tension?
surface tension is a product of cohesive forces (eg. water to water forces in a bubble) whereas capillary actionis a product of adhesive forces (eg. water climbing up a thin glass tube)
What forces move fluid from intracellular to extracellular spaces?
Capillary hydrostatic force
What is the name of the pressure that forces fluids from capillaries into extracellular spaces?
Capillary Hydrostatic Pressure
What pair of forces makes water go through the soil?
Capillary action and gravity.
What is an effect that adhesion produces?
Adhesion produces capillary action. Capillary action is liquid's ability to flow in narrow spaces without external forces like gravity.
