The first are usually called true secretions, or secretions proper, while the second are called excretions. *Excretory Work of Glands.*—The process of removing wastes from the body is called excretion. While in theory excretion may be regarded as a distinct physiological act, it is, in fact, leaving out the work of the lungs, but a phase of the work of glands.
If the skin is not kept clean, the millions of pores are liable to be partly stopped up, which results in the retention of a part of the excretory matter within the skin, where it may cause enough irritation to produce some form of cutaneous disorder, or the skin may through disuse become so inactive that too much work is thrown upon the other excretory organs, which may also become diseased from overwork and excessive irritation.
The point at which the cord is attached affords the simplest means of distinguishing the two surfaces of the placenta. Our knowledge as to how the exchange of food and excretory products between mother and child is carried on by the placenta has been gained chiefly through the microscope.
But the change is great. The modern treatment of disease relies very greatly on the old so-called natural methods, diet and exercise, bathing and massage in other words, giving the natural forces the fullest scope by easy and thorough nutrition, increased flow of blood and removal of obstructions to the excretory systems or the circulation in the tissues. "One notable example is typhoid fever.
From the ingurgitation of spirituous liquors into the stomach and duodenum, the termination of the common bile-duct in that bowel becomes stimulated into unnatural action, and a greater quantity of bile is produced from all the secretory vessels of the liver, by the association of their motions with those of their excretory ducts; as has been explained in Section XXIV. and XXV. but as all parts of the body, that have been affected with stronger stimuli for any length of time, become less susceptible of motion, from their natural weaker stimuli, it follows, that the motions of the secretory vessels, and in consequence the secretion of bile, is less than is natural during the intervals of sobriety. 2.
A general and comprehensive view of the organism includes, then, digestive apparatus and lungs as the channels of fuel-supply; blood and lymph channels as the transportation system; and muscle cells, united into muscle fibres, as the consumption furnaces, where fuel is burned and energy transformed and rendered available for the purposes of the organism, supplemented by a set of excretory organs, through which the waste products the ashes are eliminated from the system.
Though it may perhaps be stimulated into the performance of its natural action by the blood, which surrounds its origin, or by some part of that heterogeneous fluid; yet as the tears secreted by this gland are more wanted at some times than at others, its secretion is variable, like that of the saliva above mentioned, and is chiefly produced when its excretory duct is stimulated; for in our common sleep there seems to be little or no secretion of tears; though they are occasionally produced by our sensations in dreams.
Edgerton during the month of struggle has been to assist Nature in eliminating the obsolete matters of the system by all the excretory passages as preparative to the rebuilding of his system on a healthy plan by new material.
*Excretory Work of the Lungs.*—While the lungs cannot be regarded as glands, they do a work in the removal of waste from the body which must be considered in the general process of excretion. They are especially adapted to the removal of gaseous substances from the blood, and it is through them that most of the carbon dioxide leaves the body. The lungs remove also a considerable quantity of water.
Some of the contributory causes are wrong thinking, too little exercise, lack of fresh air, and ingestion of sedatives and stimulants which upset the assimilative and excretory functions of the body. In all cases the blood is unclean. The patient is suffering from autointoxication or autotoxemia. If this is true, it would follow that the treatment of all diseases is about the same.
