A branch of internal medicine concerned with the origin and treatment of tumors and tumor-related diseases.

See colloid-osmotic pressure.

A narcotic drug that is generally prescribed to manage pain. Its name is derived from the natural opiate mixture of substances, but does not contain and is not made from opium.

A branch of medicine concerned with the origin, prevention and treatment of congenital or acquired deficiencies and anomalies in the form and function of the locomotor apparatus.

Equalisation of concentration through a porous partition (membrane) between solutions of different concentrations.

Osmotic pressure develops with the use of semipermeable membranes because such membranes only allow the solvent but not the dissolved substance to pass through, so that this substance then creates pressure on the membrane.

(Combination of osmosis and molecule) Concentration of all of the osmotically active molecules in a solution expressed in volume units.

The infusion of a highly concentrated sugar solution (so as to increase the osmotic pressure of the blood) forces the influx of tissue water into the blood (eliminating oedemas) and thereby also increasing urinary excretion.
