MICROANATOMY

Detailed explanation-1: -Stratified columnar epithelium: This type of epithelium is not as common and is seen in the mucous membrane (conjunctiva) lining your eyelids, where it’s both protective and mucus-secreting. Pseudostratified columnar epithelium: This type of epithelium lines your upper respiratory tract and usually has a lot of cilia.

Detailed explanation-2: -The stratified epithelium protects the body from physical and chemical damage by creating a barrier of keratinized cells. Goblet cells are involved in maintaining a protective layer of surface tissue, like the inner lining of the stomach, through secretions such as mucus and other substances that provide a barrier.

Detailed explanation-3: -Transitional epithelium is present in the renalcalyces, ureters, bladder and urethra. Its unique appearance allows distensibility, but it is also involved in protecting the underlying tissues from toxic chemicals found in the urine.
