MICROANATOMY

Detailed explanation-1: -The transitional epithelial tissue of the urinary bladder acts like a water balloon. The ability of the cells of the transitional epithelium to stretch from round cells to thin, flat cells allows the urinary bladder to expand to hold more urine.

Detailed explanation-2: -The transitional epithelium cells stretch readily in order to accommodate fluctuation of volume of the liquid in an organ (the distal part of the urethra becomes non-keratinized stratified squamous epithelium in females; the part that lines the bottom of the tissue is called the basement membrane).

Detailed explanation-3: -Transitional Epithelium Function The tissue offers high impermeability to water and various substances because of the significant keratin deposits present in the cells. Even when fully stretched, the transitional epithelium cells offer resistance to osmotic pressure, which prevents desiccation.
