The Ureters and Urinary Bladder are Lined by ________ Epithelium

Question

The ureters and urinary bladder are lined by ________ epithelium.
A) stratified squamous
B) pseudostratified columnar
C) simple cuboidal
D) transitional
E) simple columnar

Accepted Answer

The ureters and urinary bladder need to be able to stretch and accommodate changes in volume as urine passes through them. Transitional epithelium is able to do this because it is made up of cells that can change shape from cuboidal to squamous as the tissue is stretched. This would not be possible with any of the other types of epithelium listed.
