CHAP. XVIII.

Of the Ʋreters.

THE Ureters, in Latin Meatus urinarii, are called in Greek 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, either from 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, to piss, or 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, because they keep the Urine.

They arise out of the inner Sinus of the Kid∣neys,* 1.1 whose various Pipes (nine or ten) uni∣ting into one make the Ureter.

There is one in each side.* 1.2

They are white Vessels,* 1.3 like to Veins; yet they are whiter, thicker and more nervous. They reach from the Kidneys to the Bladder, not in a direct line, but something crooked like an Ita∣lick s.

They have been thought to have two Coats,* 1.4 the one common from the Peritonaeum; the other proper: but indeed it is but one, and that pro∣per. It is strong, nervous, strengthned with oblique and streight Fibres, having small Veins and Arteries from the neighbouring parts. As to their Nerves Dr. Willis saith, that after the In∣tercostals have sent forth all the Mesenterick nerves, each Trunk descending sends forth three or four several slips that are carried into the Ure∣ters, which makes the pain so very exquisite when some viscid matter or stone sticks in them.

TAB. IV. pag. 101.

As they go out of the Kidney they pass over the Muscles Psoae (which bend the Thigh) be∣tween the two Membranes of the Peritonaeum, and descending as abovesaid, they are inserted in the Back and lower part of the Bladder, (not far from the Sphincter) running between the two proper Coats of it, about the length of an inch, and continued with its inner substance.

This insertion is oblique to hinder the regur∣gitation of the Urine,* 1.5 when the Bladder is either compressed or distended with Urine; for here is no Valve, as some have affirmed.

Although the Ureter doth not ordinarily ex∣ceed in compass a Barly-corn, yet when stones do pass, it becometh sometimes as large as a small Gut.

Their use is to receive the Urine separated from the Bloud in the Kidneys,* 1.6 and to convey it into the Bladder, thence at discretion at certain times to be emptied out of the Body.
