Study the given figure below and answer the following question: Which epithelium forms the outer layer of the skin and lines cavities and ducts?

Epithelial tissue is flat, cuboidal or columnar, forming a protective layer. The striated squamous epithelium forms the outer layer of the skin and squamous epithelium lines cavities and ducts. They are also located on the urinary bladder, respiratory organ like lungs, the tubular lining of kidneys, etc. These tissue provide underlying parts from injury. These tissues are involved in many functions like secretion, absorption, etc.

Study the given figure below and answer the following question: Which one allows diffusion of substances?

According to the given image, the epithelial tissue which allows the diffusion of substances is called squamous epithelium. They form a delicate lining in skin, oesophagus, blood vessels and lung alveoli. The transportation of substances takes place through a selectively permeable membrane. Therefore, squamous epithelium allows the diffusion of substances.
