of a mass^of tubules which, beginning in Bowman's capsules 

 in the cortex and fusing with other tubules, end in a cavity 

 termed the pelvis of the kidney. The renal artery gives rise 

 to branches which form glomeruli tufts of capillaries in the 

 glomerular organs, and the efferent vessel splits once more 

 into capillaries around the proximal end of the tubule. A 

 head of water is thus provided at the beginning of each tubule, 

 and the waste material is removed from the blood by the cells 

 of the tubules. The waste consists of organic material as urea

and uric acid, with carbonates and other salines. These are 

 carried down the tubules in a state of solution as urine to the 

 pelvis of the kidney. From this the ureter springs on the 

 indented inner border or hilum of the kidney, and the two 

 ureters open near each other on the postero-dorsal wall of the 

 bladder. 



In the male, the testes originally formed on the dorsal 

 wall of the peritoneal cavity are carried with the fold of 

 peritoneum which covers them posteriorly to the scrotal sacs, 

 where the cavity is lined by the peritoneum, now called 

 the tunica vaginalis. The testis on each side is an elongated 

 white body. Anteriorly it is connected by the vasa efferentia 

 with the epididymis. The epididymis consists of the coiled tubes 

 of the Wolffian body and leads posteriorly into the vas deferens.
