There are also certain glands situated in close relation to this duct which provide a fluid which is emitted at the same time as the spermatozoa, the whole being termed the seminal fluid.
These canals unite to form the nasal duct, which conveys the tears to the nasal cavity on the same side of the nose. When by evaporation the eyeball becomes too dry, the lids close reflexively and spread a fresh layer of tears over the surface. Any excess is passed into the nostrils, where it aids in moistening the air entering the lungs.
There is another circumstance well worthy our attention, that when by any accident this nasal duct is obstructed, the lacrymal sack, which is the belly or receptacle of this gland, by slight pressure of the finger is enabled to disgorge its contents again into the eye; perhaps the bile in the same manner, when the biliary ducts are obstructed, is returned into the blood by the vessels which secrete it?
The glow of the flames grew brighter . . . and showed me the half-rotten piles upholding the building, showed me the tidal mark upon the slime-coated walls showed me that there was no escape! By some subterranean duct the foul place was fed from the Thames. By that duct, with the outgoing tide, my body would pass, in the wake of Mason, Cadby, and many another victim!
A very important though minute occurrence must here be observed, that though the lacrymal gland is only excited into action, when we weep at a distressful tale, by its association with this nasal duct, as is more fully explained in Sect.
The seminal vesicles. The seminal vesicles are small bladder-like organs supposed originally to contain the secreted semen collected from the testes. There are two of these vesicles, from each a small duct joins the vas deferens making up what is known as the ejaculatory duct. The two ejaculatory ducts coming together in the prostate gland open into the urethra.
A little further off, the thoracic duct pours its whole contents together into a large vein situated close to the heart, and the blood has no difficulty in recognising and appropriating what belongs to him. Here, my dear little scholar, we conclude the first part of our story.
You may assure yourself of the truth of this observation, if you will attend to what passes, when you read a distressful tale alone; before the tears overflow your eyes, you will invariably feel a titillation at that extremity of the lacrymal duct, which terminates in the nostril, then the compression of the eyes succeeds, and the profusion of tears.
Route taken by the Fat.—The fat is conveyed by the lacteals from the villi to the receptacle of the chyle. At this place it mingles with the lymph from the lower parts of the body, and with it passes through the thoracic duct to the left subclavian vein. Here it enters the general circulation.
So saying they set out towards the river for a supply of water; but on descending the first elevation at the side on which the building stood, the chief, when partly down, placed his foot into a trough-like duct, running parallel with the elevation which was filled with leaves so as to obscure the sight of the water until it penetrated his moccasin.
