Blood 

 supply 



Nerves and 

 lymphat- 

 ics 



Function 



Ureters 



Bladder 



Lateral branches at level of 



Venous j base of pyramids, 

 arches i Receive blood from cortex. 



i Receive blood from pyramids. 



Veins empty into renal vein, leave 

 kidney at hilus, and empty into in- 

 ferior vena cava. 



Note — Blood from renal artery serves 

 for purposes of nourishment of kidney 

 and purposes of excretion. 



Nerves from sjTnpathetic and central 

 nervous system. 



Many are vasomotor, and by regulating 

 size of blood-vessels, influence blood 

 pressure. 



Well supplied with IjTnphatics. 



1. Process of transudation or filtration. 

 Water and saline elements are fil- 

 tered from the blood during the cir- 

 culation through the glomeruli. 



2. Secretory action of the cells lining 

 the uriniferous tubules. Urea and 

 other foreign substances are sepn 

 arated from the blood during the 

 circulation through the plexus of 

 capillaries which surrounds the 

 tubules. 



Excretory ducts. Extend from kidney to bladder. 

 Consist of expanded portion called pehas and duct. 

 Size of goose-quill. 12-18 in. long. 

 C 1. Mucous — lining. 



' 2. Muscular 1 1^""'"' l«"gitudinal layer.

 3. Fibrous — carries blood-vessels and nerves. 

 r Connect kidneys with bladder.
