Routes of Transport of Body Fluid

Routes of Transport of Body Fluid

Diffusion:

• Water move across a semi permeable membrane from an area of high solute concentration to one of lower solute concentration.

Osmosis:

• Movement of water across a semi permeable membrane from a less concentrated solution to a more concentrated solution thereby.

Filtration:

• Fluids and solutes move together across a membrane from an area of higher pressure to an area of a lower pressure.

Active Transport:

• Movement of solutes across cell membranes from a less concentrated solution to a more concentrated solution.

• Importance in maintaining the differences in sodium and potassium ion concentration of ECF and ICF.

• Na+ concentration are higher in ECF and K+ concentrations are higher in ICF .

• To maintain these proportions, an active transport mechanism (Na+- K+ pump) is activated.
