The Reins or Kidneys are Parts of a Fleshy Consistence, harder and more firm than that of the Liver and Spleen: They are both situated in the sides of the Umbilical Region, upon the Muscle Psoas, between the two Tunicks of the Peritonæum; but the Right is lower than the Left: Their Shape resembleth that of a French Bean, and they receive Nerves from the Stomach, whence Vomitings are frequently occasion'd in the Nephritical Colicks: They are fasten'd to the Midriff, Loins, and Aorta, by the Emulgent Arteries; as also to the Bladder by the Ureters. The Right Kidney likewise adheres to the Gut Cæcum, and the Left to the Colon. Their Office is to filtrate or strain the Urine in the Pelves or Basons, which they have in the middle of their Body on the inside, and
to cause it to run thro' the Vessels call'd Ureters into the Bladder.
Immediately above the Reins on each side, is a flat and soft Glandule, of the thickness of a Nut; they are nam'd Renal Glandules, or Capsulæ Atribiliariæ, because they contain a blackish Liquor, which (as they say) serves as it were Leaven for the Blood, to set it a fermenting.
What is the Bladder?
It is the Bason or Reserver of Urines, of a Membranous Substance as the Stomach, being plac'd in the middle of the Hypogastrick Region; so that it is guarded by the Os Sacrum behind, and by the Os Pubis before: Two Parts are to be distinguish'd therein, viz. its Bottom and Top; by its Membranous Bottom it is join'd to the Navel, and suspended by the means of the Urachus, and the two Umbilical Arteries which degenerate into Ligaments in adult Persons: As by its fleshy Neck, longer and crooked in Men, and shorter and streight in Women it cleaves to the Intestinum Rectum in the former, and to the Neck of the Womb in the latter. Lastly, its Office is to receive the Urines to keep them, and to discharge them from time to time.
What are the Genitals in Men?
They are the Spermatick Vessels, the Testicles, and the Penis. The Spermatick Vessels are a Vein and an Artery on each side; the former proceeding from the Aorta, or thick Artery of the Heart; and the other from the Branches of the Vena Cava of the Liver. These Arteries and Veins are terminated in the Body of the
Testicles, which are two in Number, enclos'd within the Scrotum.
The Office of the Testicles is to filtrate the Seed, which is brought thither from all the parts of the Body, thro' the Spermatick Vessels, called Præparantia, and afterwards to cause it to pass thro' others nam'd Deferentia, to the Vesiculæ Seminales, from whence it is forc'd into the Ureter, thro' two small and very short Canals.
The Penis or Yard is a Nervous and Membranous Part, well furnish'd with Veins and Arteries, containing in the middle the Canal of the Ureter: Its Extremity, which consists of a very delicate and spongy sort of Flesh, is call'd Balanus, or Glans, and the Nut, the Skin that covers it being nam'd the Præputium, or the Fore-Skin. Thus by the means of this swell'd Part, and stiff thro' the affluence of the Spirits, the Male injects his Seed into the Matrix of the Female, to propagate his Kind.
