Epithelial tissue varies in thickness based on its specific functions and locations in the body. Single-layered (simple) epithelium is typically found in areas where absorption, secretion, or filtration occurs, such as in the lungs and intestines, allowing for efficient exchange. In contrast, multi-layered (stratified) epithelium provides protection against physical and chemical stress, making it suitable for areas like the skin and the lining of the mouth. The structure of the epithelium is thus adapted to meet the functional demands of different tissues.
stratified squamous epithelium
So, think of parts of the body where stratified and simple epithelium line.The stomach and small intestine, for example, are lined with simple epithelial tissue, but the skin, vagina and oesophagus are composed of stratified epithelial tissue.So areas where there isn't a huge amount of movement required are lined with simple epithelium (the stomach just secretes substances and the small intestine absorbs and secretes; absorption is made easier by having just the one layer). But the skin, vagina and oesophagus have to deal with a lot mechanical stress and so simple epithelium wouldn't be suitable which is why so many layers are needed; hence they are composed of stratified epithelium.Stratifed epithelia are two or more cells thick and simple epitheium are one cell thick
tattoo ink would have to be injected into the connective tissue layer (specifically the matrix). If it were injected into the superficial epithelium then it would be lost as the skin cells die & fall off the body.
Human epithelial cells can vary in shape depending on their type and location in the body. However, they are generally described as either thin and flat (squamous) or cuboidal (boxlike). Squamous epithelial cells are typically found in areas where rapid diffusion or filtration occurs, while cuboidal epithelial cells are more common in glands and ducts. Thus, both descriptions can apply depending on the specific epithelial tissue being referred to.
Connective tissue would be better suited to cushion the kidneys against a blow due to its more elastic and supportive properties compared to epithelial tissue, which primarily functions as a protective covering. Connective tissue, such as adipose tissue or the renal capsule, can provide a cushioning effect to absorb and distribute the impact of a blow, helping to protect the kidneys from injury.
Stratified epithelium is a type of epithelial tissue that consists of multiple layers of cells. It is found in areas that require protection from mechanical or chemical stress, such as the skin or the lining of the esophagus. The layers provide strength and durability to the tissue.

Their apparent number of layers;simple epithelium with a single-layer offer less protection than Stratified epithelium having multiple layers. Also, simple epithelium functions in moving materials across its surface.

No, epithelial tissue is primarily composed of closely packed cells with minimal extracellular matrix. The extracellular matrix is more abundant in connective tissue, which provides structural support and anchorage for epithelial cells.
Epithelial tissue coats surfaces in the body.
endocrine (where the secretions are put directly into the bloodstream) or exocrine (where the secretions are carried to the epithelial surfaces)

No it is false. A thick one layer protects more protection.
Epithelial tissue or more commonly the epidermis. The epidermis is the skin on your body and it is also the bodies largest organ.
