What epithelial tissue is more than one layer thick and surface cells are flattened?
stratified squamous epithelium
How do simple and stratified epithelial tissues differ?
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
When you get a tattoo's would you expect the ink to be inject into the epithelial layer of your skin or the connective tissue layer.why?
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.
Would epithelial or connective tissue be best to cushion the kidneys against a blow?
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.
Is fat made up of epithelial tissue?
Hope this helpsEpithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the covering or lining of all internal and external body surfaces. Epithelial tissue that occurs on surfaces on the interior of the body is known as endothelium. Epithelial cells are packed tightly together, with almost no intercellular spaces and only a small amount of intercellular substance. Epithelial tissue, regardless of the type, is usually separated from the underlying tissue by a thin sheet of connective tissue; basement membrane. The basement membrane provides structural support for the epithelium and also binds it to neighbouring structures.Types of Epithelial TissueEpithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as simple epithelium. If it is two or more cells thick such as the skin, it is known as stratified epithelium. Simple epitheliumSimple epithelium can be subdivided according to the shape and function of its cells.Squamous (pavement) epithelium.Squamous cells have the appearance of thin, flat plates. The shape of the nucleus usually corresponds to the cell form and help to identify the type of epithelium. Squamous cells, for example, tend to have horizontall flattened, elliptical nuclei because of the thin flattened form of the cell. They form the lining of cavities such as the mouth, blood vessels, heart and lungs and make up the outer layers of the skin.Also does these things as tissueProtectionEpithelial cells from the skin protect underlying tissue from mechanical injury, harmful chemicals, invading bacteria and from excessive loss of water.SensationSensory stimuli penetrate specialised epithelial cells. Specialised epithelial tissue containing sensory nerve endings is found in the skin, eyes, ears, nose and on the tongue.SecretionIn glands, epithelial tissue is specialised to secrete specific chemical substances such as enzymes, hormones and lubricating fluids.AbsorptionCertain epithelial cells lining the small intestine absorb nutrients from the digestion of food.ExcretionEpithelial tissues in the kidney excrete waste products from the body and reabsorb needed materials from the urine. Sweat is also excreted from the body by epithelial cells in the sweat glands.DiffusionSimple epithelium promotes the diffusion of gases, liquids and nutrients. Because they form such a thin lining, they are ideal for the diffusion of gases (eg. walls of capillaries and lungs).CleaningCiliated epithelium assists in removing dust particles and foreign bodies which have entered the air passages.Reduces FrictionThe smooth, tightly-interlocking, epithelial cells that line the entire circulatory system reduce friction between the blood and the walls of the blood vessels.
What is the epithelium that occurs in a thick layer of cells?
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.
What epithelial tissue is more than one layer thick and surface cells are flattened?
stratified squamous epithelium
How does a simple epithelial tissue differ from a stratified epithelial tissue in structure?
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.

Is large amount of extracellular matrix a characteristic of epithelial tissue?
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.
What kind of tissue covers the surfaces of structures inside the body?
Epithelial tissue coats surfaces in the body.
What are two ways that epithelial tissue are classified?
endocrine (where the secretions are put directly into the bloodstream) or exocrine (where the secretions are carried to the epithelial surfaces)

Does a thinned ozone layer offer less protection than a thick one?
No it is false. A thick one layer protects more protection.
Tissue that makes outer covering in humans?
Epithelial tissue or more commonly the epidermis. The epidermis is the skin on your body and it is also the bodies largest organ.
What word describes tissue that has more than one layer?
Stratified tissue describes tissue that has more than one layer of cells. This type of tissue is common in areas of the body that require protection or support, such as the skin and lining of the mouth and esophagus.
