NEET BIOLOGY

Detailed explanation-1: -The pseudostratified epithelium is made up of a single layer of columnar or cuboidal cells but it appears to be multilayered because the nuclei are not present at the same level instead are present at different levels in each cell. It is mostly found in the trachea, bronchi, and salivary glands.

Detailed explanation-2: -Ciliated pseudostratified columnar epithelia is the type of respiratory epithelium found in the linings of the trachea as well as other respiratory tract, which allows filtering and humidification of incoming air.

Detailed explanation-3: -Kidney tubules-Cuboidal cells.

Detailed explanation-4: -Found most heavily along the respiratory tract, pseudostratified ciliated columnar epithelial cells help trap and transport particles brought in through the nasal passages and lungs.

Detailed explanation-5: -The presence of pseudostratified columnar epithelium in the upper respiratory tract (composed of the nose, trachea and bronchi) protects the lungs from these irritants. Goblet cells of the epithelium secrete mucus to trap particles and prevent them from traveling further down respiratory passages.
