Simple Cuboidal Epithelium is present in

The mucosal lining of the trachea is composed of pseudostratified ciliated columnar (respiratory) epithelium.The epithelial lining of bronchioles ranges from ciliated simple columnar with occasional goblet cells in larger bronchioles to simple cuboidal (many with cilia) with occasional club cells (also known as Clara cells) and no goblet cells in smaller bronchioles. The epithelium of terminal bronchioles is composed of club cells and cuboidal cells, some with ciliaRespiratory bronchioles are similar in structure to terminal bronchioles, in that their epithelium is a simple cuboidal epithelium rich in club cells and some ciliated cells, but this epithelium is broken up by the presence of thin-walled, pouch-like structures, known as alveoli, composed of an attenuated simple squamous epithelium, where gaseous exchange (O2 for CO2) can occur.Reference: Krishna Garg Histology; 5th edition; Page no: 130
