GENERAL HISTOLOGY

Detailed explanation-1: -The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.

Detailed explanation-2: -Simple squamous epithelia are found in alveoli and capillaries of lungs where gas exchange occurs, kidney glomerulus and tubules where filtration and diffusion processes form urine, and capillaries where diffusion and osmosis occur.

Detailed explanation-3: -Squamous, or flattened, epithelial cells, very thin and irregular in outline, occur as the covering epithelium of the alveoli of the lung and of the glomeruli and capsule of the kidney.
