Structure of the Kidney.—The kidney is a compound tubulargland. The uriniferous tubules composing it may be roughlyseparated into a secreting part comprising the capsule, convolutedtubes, and loop of Henle, and a collecting part, the so-called straightor collecting tube, the epithelium of which is assumed not tohave any secretory function. Within the secreting part the epithe-lium differs greatly in character in different regions; its peculiaritiesmay be referred to briefly here so far as they seem to have a physio-.
