In its wide part the epithelial lining consists of a single layer of squamous cells which change gradually toward the narrow part first to polyhedral, then to two or three layered, still farther to four or five layered transitional type. At the wide part the lamina propria is very delicate and becomes better developed at the narrow part. An inner circu- Glomerulus Renal vein — Renal artery. Renal pelvis

Renal pelvis Capsule Fig. 61.—Kidney, region of pelvis and papilla. (X30.) lar smooth muscle layer appears first about at the level where the epithelium becomes stratified, while still lower an outer longitudinal smooth muscle layer is also distinguishable. Outside of this, loose connective tissue con- taining many adipose cells surrounds the narrow end of the pelvis and the ureter which arises here (Fig. 61). The ureter is a narrow tube which conducts the urine from the kidney to the bladder. Its wall is composed of transitional epithelium, a fibrous lamina propria, an inner circular and an outer longitudinal smooth muscle coat and the adventitia consisting of loose connective tissue and many.
