Functions in filtration, diffusion, osmosis, and surface coverings
A
simple squamous
B
stratified columnar
C
pseudostratified columnar
D
stratified cuboidal
Explanation: 

Detailed explanation-1: -Simple squamous epithelial cells form a membrane that allows selective diffusion of materials to pass through. Diffusion helps with filtration, absorption and secretion functions. Sensory reception: Sensory nerve endings that are embedded in epithelial tissue allow your body to receive outside sensory stimuli.

Detailed explanation-2: -Simple squamous epithelial cells function as mediators of filtration and diffusion. Due to their simple and thin construct, they allow for easy transmembrane movement (i.e. across the membrane, and through the cell) of small molecules.

Detailed explanation-3: -Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

Detailed explanation-4: -Functions of Simple Squamous Epithelium These epithelia are common where absorption or transport of materials is important. They also play a role in diffusion, osmosis and filtration. This makes them important in the kidney, in the alveoli of lungs and in the walls of capillaries.
