Solution

Simple squamous epithelium: Composed of flat, tile-like polygonal cells.
Function: Protection, excretion, gas exchange, and secretion of coelomic fluid.
Location: found in terminal bronchioles and alveoli of lungs.
Simple cuboidal epithelium: Consists of short, cube-shaped cells.
Function: Protection secretion,absorption,excretion and gamete formation.
LOCATION: found in PCT and DCT of nephrons of kidney.
Simple columnar epithelium: Composed of elongated cells placed side by side like a column.
Function: Protection, secretion and absorption.
LOCATION: found in the intestine.
Glandular epithelium is a type of epithelial tissue which covers the glands (both exocrine and endocrine) of our body.
Function- The main function is SECRETION. Both endocrine and exocrine glands produce their secretions through the glandular epithelium via special cells called goblet cells.
Location: the entire surface of the human body and also the internal organs.
