- n. The passage of gases, vapors, or liquids through membranes or porous media from within outward, in the phenomena of osmosis, the reverse process being called endosmosis. See endosmosis, osmosis.
He finds that the vessels of the body, without undergoing extensive structural alteration, can by exosmosis rid themselves of fluid to an amount of eight per cent. of the body weight of the subject of the experiment.
The result is that a current of endosmosis takes place from the water toward the juice in the cells, and a current of exosmosis from the juice toward the water.
This process is now to a large extent superseded by what is called the diffusion process, depending on the well known physical phenomena of _endosmosis_ and _exosmosis_.
Now, it is pretty well conceded by physiologists, that electricity stimulates the secretory as well as excretory organs; that it furthers endosmosis and exosmosis — by its electrolytic influence in a physical, by its influence on the nervous system in a catalytic manner, in short, and by virtue of these properties, that it greatly
Solutions of salt or sugar, denser than the plasma, give them a stellate or crenated appearance (exosmosis) (Fig. 453, d), but the usual shape may be restored by diluting the solution to the same tonicity as the plasma.
The vessels thus become filled with an unusual quantity of the circulatory fluid, which distends their coats, and facilitates the pouring out, or the exosmosis of the watery portion of the Blood into subjacent cavities or neighbouring tissues.
_ Probably the most important obstruction to the exosmosis is at the angle close to Schlemm's canal. "
If, now, by way of my stomach, through endosmosis and exosmosis, I get them more water, the proper conditions will return. "
