GENERAL HISTOLOGY

Detailed explanation-1: -The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.

Detailed explanation-2: -The ciliated columnar epithelium is found in sperm ducts, lining the trachea, bronchi, kidney tubules, respiratory tract, and oviducts.

Detailed explanation-3: -Ciliated epithelium in the respiratory tract helps in mobilising the mucus and keeping the respiratory tract clear and unobstructed.

Detailed explanation-4: -Ciliated epithelium lines the human respiratory tract from the posterior third of the nose to the bronchioles. In humans, cilia are present in the paranasal sinuses, the Eustachian tubes, the ependymal lining of the central nervous system, in the male vasa efferentia, and the female oviducts, among other structures.
