The kidney is held in position throngh the at- tachments of the fascia renahs and by the apposition of the neighboriiis viscera. General Structure of the Kidney.— ^„e:a chibhosa The Uiilncy is invested by a capsule of interlacing bundles of fibrous connective tissue (tunica fibrosa), which forms a firm, smooth covering for the organ. The cap- sule can be easily stripped off, but in doing so, numerous fine processes of connective tissue and .small bloodvessels are torn through. Beneath this coat, a thin wido- meshed network of unstriped muscle fibres forms an incomplete covering. When the capsule is removed, the surface of the kidney is found to be smooth and even, and of a very deep red color. In infants, fissures extending for some depth may be seen on the surface of the organ, a remnant of the lobular construction of the gland (Fig. 1105). The kidney is dense in texture, but is easily lacerable by mechan- ical force. If a vertical section of the kidney be made from its convex to its concave border, and the loose tissue and fat removed from around the vessels and the excretory duct, it will be seen that the organ consists of a central cavity surrounded, except at the hilum, by the proper kidney substance (Fig. 1113). This central cavity is called the renal sinus (sinus renalis) and is SUPERIOR lined by a prolongation of the cap- sule, which is continued around the lips of the hilum. Through the hilum the bloodvessels of the kidney and its excretory duct pass, and therefore these structures, upon entering the kidney, are contained within the sinus. The excretory duct or ureter begins as a funnel-shaped sac, the pelvis of the ureter (pelvis ureter- iciis s. renalis). The pelvis begins at the renal papillfe in the form of a number of truncated cup-shaped infundibular divisions, the calices minores, into each of whic
