Crossword-Solution: DIALYSIS 8 letters, 3 clues 🏆 scrabble score: 12

Colloids are known to possess some slight power of dialysis; and on placing the leaves of a Primula in water, and others in syrup and diffused starch, those in the starch became flaccid, but to a less degree and at a much slower rate than the leaves in the syrup; those in water remaining all the time crisp.] From the foregoing experiments and observations we [page 389] see that objects not containing soluble matter have little or no power of exciting the glands to secrete.

The force here concerned is a force known as _osmosis_ or _dialysis_, and is always exerted when two different solutions of certain substances are separated from each other by a membrane.

After digestion, therefore, the food is dissolved in the liquids in the stomach and intestine, and is in proper condition for dialysis.

Here are proper conditions for osmosis, and this process of dialysis will take place whenever the intestinal contents holds more dialyzable material than the blood.

Here again we have a membrane (i.e., the wall of the blood-vessel) separating two liquids, and since the lymph is of a different composition from the blood, dialysis between them is sure to occur, and the materials which passed into the blood in the intestine through the influence of the osmotic force, now pass out into the lymph under the influence of the same force.
