Verified step by step guidance

Understand the function of the urinary tract: The urinary tract needs to stretch and expand to accommodate varying volumes of urine. This requires a specialized type of epithelial tissue.

Review the characteristics of epithelial tissue types: Simple squamous epithelium is thin and allows for diffusion, pseudostratified ciliated columnar epithelium is involved in secretion and movement of mucus, and stratified columnar epithelium provides protection but lacks the ability to stretch significantly.

Focus on transitional epithelium: Transitional epithelium is uniquely designed to stretch and recoil. It is found in areas like the bladder, ureters, and part of the urethra, where expansion and contraction are necessary.

Examine the structure of transitional epithelium: This tissue has multiple layers of cells that can change shape. When stretched, the cells flatten; when relaxed, they appear more rounded or cuboidal.

Conclude why transitional epithelium is the correct answer: Its ability to stretch and return to its original shape makes it ideal for the urinary tract, distinguishing it from other epithelial types listed in the problem.
