lining the mouth
diffusion is occur when different concentration gradient is applied
what problems can occur if a highway have sharp bends
NO!!! It does not occur naturally. However, its mineral ores are very common. e.g. Haematite, Magnetite.
For the Doppler effect to occur the measured object must be in motion (radial velocity) relative to the emitter of a wave.
A standing wave can occur only at specific frequencies that are called natural frequencies.
Through stratified squamous epithelium absorption will be very poor and person will die of starvation.Malabsorption could occur if the digestive tract were lined with stratified squamous epithelium instead of simple columnar eqithelium.
The epithelium is non-keratinized stratified squamous epithelium with scattered mucus glands. Let's go through each of these characteristics: Stratified - Many cells so that friction from esophageal objects does not scrape off deep cells. Squamous - Flat cells that allow sloughing off and closer packing Mucus Glands - Lubricate the passage of food down esophagus All these things help the function of esophagus to transfer food from mouth to stomach!
Epithelial tissue is classified as simple (single layer of cells) or stratified (multiple layers of cells). Simple epithelium is found in areas where absorption and filtration occur, while stratified epithelium is found in areas subject to mechanical stress and protection, such as skin.
Simple squamous epithelium consists of a single layer of flat cells that allow for diffusion to occur. This type of epithelium is found in areas where rapid diffusion or filtration is necessary, such as in the lungs for gas exchange or in the lining of blood vessels.
Dysplastic lesions of squamous epithelium most often occur in the cervix of the uterus, which is known as cervical intraepithelial neoplasia (CIN). These lesions can also be found in other areas such as the oral cavity, esophagus, anus, and skin.
the addition of keratin to the stratified squamous epithelial cells in the epidermis. Begins in the stratum spinosum and continues into the stratum granulosum.
Simple For example, simple cuboidal epithelium A layered version would be Stratified cuboidal epithelium
You would find simple squamous epithelial cells where you'd want diffusion to occur, like in capillaries or alveoli.
Squamous cells are a type of epithelial cell. Epithelial cells are cells that line the surface of an opening. For example skin cells are epithelial because they line the opening of the skin to the outside air. The lining of blood vessels are squamous as well, because they line the surface of the blood vessels. The basic types of epithelial cells are squamous, cuboidal, columnar, and transitional. The description can become more detailed such as stratified squamous and pseudostratified columnar. Squamous cells are very thin, flat cells. An example of squamous cells stacked on top of each other (stratified squamous) would be the outer layer of your skin. In fact these squamous cells are kertatinized and contain no active nucleus, and function mainly as a barrier to your inner body.
Simple squamous epithelium is a flat single layered tissue that allows for diffusion to occur efficiently due to its thin structure and close arrangement of cells. It is found in areas where substances need to pass through easily, such as in the alveoli of the lungs where gas exchange occurs.
Bowman's glands, also known as olfactory glands, occur in the olfactory epithelium. These glands secrete mucus that helps to moisten and protect the olfactory epithelium, as well as provide a medium for odor molecules to dissolve in, allowing for olfaction, or the sense of smell.
Epithelial tissue forms lining layers of structures in the body.ExamplesThere is epithelial tissue in the skin.Epithelial tissue forms the inner lining of the stomach, lungs, and blood vessels.There are different types of epithelial tissue, distinguished by the different shapes of their constituent cells: squamous, cuboidal, and columnar.Squamous (pavement) epithelium consists of flattened cells. There are multiple layers of this type of epithelium in human skin. It is protective in function.Cuboidal epithelium is made up of cells shaped like cubes. It is found in the kidney, for example, and in involved in absorption and secretion. Columnar epithelium has tall cells. They occur, for example, in the small intestine, where they are involved in secreting digestive juices and absorbing the products of digestion.
