Verified step by step guidance

Understand the structure of transitional epithelial tissue: Transitional epithelium is a type of tissue consisting of multiple layers of epithelial cells which can contract and expand. It is found in areas of the body that need to stretch, such as the bladder.

Identify the locations where transitional epithelial tissue is commonly found: This tissue is primarily located in the urinary system, including the bladder, ureters, and part of the urethra.

Consider the functional requirements of these locations: The bladder and ureters need to accommodate varying volumes of urine, which requires the ability to stretch and then return to their original shape.

Relate the structure to its function: The unique ability of transitional epithelium to stretch and then return to its original shape is crucial for the function of the urinary bladder, which must expand as it fills with urine and contract as it empties.

Conclude the primary function: Based on the structure and location, the primary function of transitional epithelial tissue is to allow stretching and distension, accommodating fluctuations in volume within the urinary system.
