Block1/Fig 5. 93W3039 Transitional epithelium, H&E.

block1_16.jpg - Fig 5. 93W3039 Transitional epithelium, H&E. Thismicrograph is taken from the cross-sectioned ureter. The lumenof the ureter is lined by transitional epithelium (TE). The uretersare muscular tubes that carry urine from the kidneys to thebladder. The wall of the ureter contains smooth muscle (Sm).Because of contraction of the smooth muscle, the luminalsurface is characteristically folded, thus creating a star-likelumen. Surrounding the muscular wall is a loose connectivetissue containing adipose tissue (Ad) and blood vessels (BV).The wall of the ureter in the rectangular area in Fig 7a isexamined at higher magnification as in Fig 7b. Adipose tissue(Ad), smooth muscle (Sm) and blood vessels (BV) could beseen in this micrograph.
