Exercise in the open air favors the excretion of waste matters which otherwise would be deposited in the cellular tissues.
The kidneys, therefore, are not liable, as in temperate climates, to be irritated by excrementitious matter, for the stress of excretion falls upon the lungs.
The uppermost is the opening of the ureter giving exit to the excretion from the kidneys; the lower is the opening of the duct from the reproductive organs and is called the genital aperture.
In the skin are many glands which by theirexcretion keep it soft and moist.
Characteristic of this disease is the continued excretion of very large quantities of pale, watery urine, containing neither albumin nor sugar.
Excretion of chlorids is diminished in nephritis and in fevers, especially in pneumonia and inflammations leading to the formation of large exudates.
This sediment seldom indicates an excessive excretion of phosphates.
They are sometimes due to excessive excretion of phosphoric acid, but usually merely indicate that the urine has become, or is becoming, alkaline.
Excretion of these substances is greatly increased by a diet rich in nuclei, as sweetbreads and liver.
Factors which favor an early deposit are high acidity, diminished urinary pigments, and excessive excretion of uric acid.
But in the excretion of water there exists a compensating relation between the skin, kidneys, and bowels,--particularly between the two former.
The excretion of faeces continues when no food is taken.
This name is applied to medicines which in various ways increase the quantity or promote the excretion of the saliva.
In such instances, these parts of the urine may either be separated by the kidneys from the blood in a solid state, or may be deposited from the urine after excretion or on cooling.
The circumstances which determine theexcretion of saline matters appear to be simple in nature.
But it has been said by some to increase the amount of Urea in the urine; by others, to promote the excretion of Uric acid.
Thus the bile is poured out during the process of digestion; and the peristaltic motion and extra-secretion, produced in the bowel by the action of a purge, causes likewise a sympathetic formation and excretion of bile.
In Gout and Rheumatism, remedies of this order may be of service by promoting the excretion from the blood of the uric or lactic acid formed there.
Medicines which are thought to stimulate the action of the liver, and to promote the excretion of bile, are called Cholagogues.
The first result of their action is to stimulate the proper secretion of a gland; but when it is pushed to a further extent, they may actually case the excretion of some of the natural constituents of the blood.
Those effete matters which it is the function of the bowels to excrete from the blood, and whose excretion is promoted by purgative medicines, have an action on the brain which in some degree resembles that of Opium.
As in glycosuria, theexcretion of sugar (glucose) in the urine.
Bromidrosis; theexcretion of perspiration of a strong odor.
There are scale insects whose excretion forms a black mold on the leaves and affects the nutrition by cutting off the sunlight.
The effect of caffeine on nitrogenousexcretion and partition.
They observe that the increase in excretion of uric acid after the addition of caffein to the diet seems to be proportional to the quantity of caffein taken, and equivalent to from 10 to 15 percent of the ingested caffein.
It reacts on the kidneys as a diuretic, and increases the excretion of uric acid, which, however, is not to be taken as evidence that it is harmful in gout.
Many other data were obtained showing diminished excretion of uric acid, ethereal sulphates, phosphoric acid, etc.
This inoffensive character remains indefinitely after excretion until the ash completely dries or disintegrates like rotten stone or wood.
From the capsules, the excretion passes through the tubules into the pelvis, and on through the ureters to the bladder.
The amount of this excretion evaporated from the general surface is very considerable, and is modified as becomes necessary from the varied conditions of the temperature.
The Malpighian capsules are really the beginning of the tubules, for here the work of excretion begins.
This explains the increasedexcretion of the kidneys in cold weather.
The means by which secretion and excretionare effected are, however, identical.
An analogous fact with respect to the sweet excretion from the stipules of Vicia sativa has been already given.
The excretion of a sweet fluid by glands seated outside of a flower is rarely utilised as a means for cross-fertilisation by the aid of insects; but this occurs with the bracteae of the Marcgraviaceae, as the late Dr.

The urinary excretion from the kidneys collecting in the urinary bladder is passed out periodically through the urethra.
The stimulation of excretion through the kidneys and skin may be an exceedingly important thing, particularly if one has just caught a cold and wishes to establish free excretion.
Excretion is also partly explained, but here again we finally must refer certain processes to the vital powers of active cells.
Although very careful experiments have been made, it has as yet been found impossible to detect any rise in temperature when a nerve impulse is passing through a nerve, nor is there any demonstrable excretion of waste products.
At the same time the bath opens the pores which assist in the excretion of degenerated matter produced by the disease, and fosters the reception of oxygen.

The solution and excretion of diseased matter from other points than the inflamed spots will thereby be effected, and these will be unburdened and calmed accordingly.
The effect is far otherwise when the pressure of blood into the diseased part is moderated, if the dissolution andexcretion of the matter that causes the disease, takes place, not in one spot only, but is distributed over the entire body.
