A type of epithelium consisting of a single layer of flat cells which allow diffusion to occur is?
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.
Where would you expect to find simple squamous epithelium?
You would find simple squamous epithelial cells where you'd want diffusion to occur, like in capillaries or alveoli.
What is a flat single layered tissue which allows for diffussion to occur?
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.
What type of glands occur in olfactory epithelium?
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.
What tissue is classified as simple or stratified?
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.
Where does non keratinised stratified squamous epithelium not occur?
lining the mouth

What would happen if the digestive tract was lined with stratifed squamous epithelium instad of simple columnar epithelium?
Stratified squamous epithelium is thicker and more protective than simple columnar epithelium, which could impair nutrient absorption and secretion processes in the digestive tract. The change could lead to decreased efficiency in digestion and absorption due to the increased thickness of the epithelial lining, potentially causing digestive issues.
Must skin cancer moderate dysplastic nevus be removed?
Dysplastic nevi are not actually considered cancer. Sometimes melanomas can occur within one, but rarely. The presence of dysplastic nevi are indicative of an increased risk for cancer in the future. The more in number you have, the more likely melanoma will occur, usually as a new "mole." Most doctors remove moderate to severe displastic nevi.
How does the epithelia of esophagus relate to its function?
The epithelium of the esophagus is made up of stratified squamous cells, which provide protection against mechanical damage due to the swallowing of food. This type of epithelium is well-suited to withstand abrasion and friction as food passes through the esophagus on its way to the stomach. Additionally, the epithelial cells can regenerate quickly to repair any damage that may occur due to normal wear and tear.

How many lesions on the brain occur with progressive multifocal leukoencephalopathy?
Several

How many brain lesions occur with progressive multifocal leukoencephalopathy?
There is no set amount of brain lesions that occur with progressive multifocal leukoencephalopathy. The amount can range from one to several and will vary depending on the amount of damage the virus which causes the disease has a chance to do.
What is epithelialized tissue?
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.
Can chickenpox grow on eyelashes?
Chickenpox lesions occur on skin. They can't occur on eyelashes, but can occur on skin-covered or mucous membrane-covered structures of or near the eye.
