Unlike the skin, the action of these bodies is purely excretory, and to them is due the purification of the blood. Structure of the kidney.— The ordinary lamb's kidney which may be obtained from the butcher serves well to demonstrate the structm-e of this important organ. Removing the fat from the outside we find the reddish- brown kidney within, still surrounded with a trans- parent membrane or capsule. This membranous capsule is called the renal capsule. Remove this and we have the kidney. Viewed from the out- side it shows a bean- shaped outline, being convex on one side and concave on the other. In the depression on the concave side may be made out the connect- ing renal vein and artery and the ureter at the point where they enter the body of the kidney. If we cut the kidney lengthwise the cut surface shows the following areas (see Fig. 169). As it enters the kidney the narrow ureter is seen to widen into a cavity called the pelvis. From this pelvis extend branches forming what are called calices. The solid portions show two layers. The outer is caUed. WA.
