$</p><p>\huge{\underline{\mathfrak{\ ANSWER;}}}$

➣Squamous epithelial cells are thin, flat cells. Simple squamous epithelium is a single layer of squamous cells, which form a thin, delicate lining.

➣Such lining is generally utilized where transportation of substances takes place through selective permeability.

➣The trachea is a windpipe, which connects larynx and pharynx to the lungs. Trachea carries the wind to lungs.

➣So, trachea need not be having the selective permeable lining.

The intestine is the place where absorption of nutrients takes place.

➣For this function, tall columnar cellular lining is utilized.

➣Oviduct carries out the function of pushing the fertilized ovum or zygote towards the uterus.

➣For this purpose, the inner surface of the oviduct is lined by ciliated epithelium, which moves and pushes the zygote.

➣Lung alveoli show gas exchange. For this purpose, alveoli show selectively permeable lining of simple squamous epithelial cells.
