Which of the following is true about epithelia?

Question

Quizplus · Accepted Answer

Endothelium is a type of simple squamous epithelium that forms a slick surface lining all hollow cardiovascular organs, such as the heart and blood vessels.

Answer: B
 Simple epithelia are often found in areas of the body where secretion, absorption, and filtration occur, such as the lining of the digestive tract, respiratory tract and urinary bladder. They are not commonly found in areas of high abrasion, which require more protection.

Answer: False
 Pseudostratified epithelia are not commonly keratinized. Keratinization is the process of hardening and toughening of the epithelial cells by the production of the protein keratin. Pseudostratified epithelia can be found in the respiratory tract and typically have cilia that help move mucus and debris.

Answer: False
 Stratified epithelia are not necessarily associated with filtration. Stratified epithelia are found in areas that require protection from physical or chemical stress, such as the skin or lining of the mouth.
