The conducting passageways of the respiratory system (nasal cavity, trachea, bronchi and bronchioles) are lined by pseudostratified columnar epithelial tissue, which is ciliated and which includes mucus-secreting goblet cells. This epithelium is exceedingly thin to facilitate diffusion of oxygen and CO2.Click to see full answer. Similarly, what is the role of goblet cells in Pseudostratified ciliated columnar epithelial tissue of the upper respiratory tract?They secrete mucus which lubricates the apical(upper) surface of the respiratory lining and traps debris and other particles that are being inhaled.Subsequently, question is, where is Pseudostratified ciliated columnar epithelium found in the body? Ciliated pseudostratified columnar epithelium cells are found in places such as the trachea and upper respiratory tract, where their cilia and mucous secretions help collect foreign materials so you can cough or sneeze them out. Similarly, it is asked, are goblet cells found in Pseudostratified? 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.Where is Pseudostratified epithelium most commonly found in the human body?Ciliated pseudostratified columnar epithelia is the type of respiratory epithelium found in the linings of the trachea as well as the upper respiratory tract. Non-ciliated pseudostratified columnar epithelia are located in the prostate and membranous part of male vas deferens.
