Saquamous cells are flat cells. Single cell layer of these squamous cells is called saqumous cell epithelium. The stratified epithelium means formed of layers [strata] of cells which may or may not be squamous cells. The functions of these layers are different.

What tissue protects the body by covering its free surfaces and lining its cavities?

The tissue which covers and lines body cavity is called epithelium. Depending upon the site it can be squamous, stratifed squamous, columnar, and transitional epithelium


How the structure of epithelial tissue help it carry out its functions in the body?

Simple squamous epithelium consists of one layer of thin, flat epithelial cells resting on a basement membrane formed of connective tissue. It is found in such places as the alveoli of the lung and lining blood vessels. Squamous epithelial cells are flat, tightly adherent to each other, thin, and have a smooth surface. Their minute thickness serves them well in the lung alveol. the alveoli are the site of gas exchange between the air in the lungs and the gases in the blood, which occurs by diffusion. The rate of diffusion is inversely dependent on the thickness of the surface through which diffusion occurs; the thicker the layers, the slower the diffusion. Gas exchange requires quick diffusion, therefore thin squamous epithelial cells are excellent for the job.Blood flow in blood vessels requires the lining surface of the vessels to be smooth, to reduce friction and aid blood flow. the smooth surface of squamous epithelial cells serves them well for this job as well.


What are the squamous pneumocytes?

Squamous pneumocytes, also known as type I pneumocytes, are a type of cell lining the alveoli in the lungs. They are thin and flat cells that are responsible for gas exchange in the lungs, allowing oxygen to pass from the alveoli into the bloodstream while facilitating the removal of carbon dioxide.


What is the difference between epithelial and epithelium?

Epithelium refers to a layer of cells that line the surfaces of organs, blood vessels, and cavities in the body. Epithelial, on the other hand, is the adjective form that describes something related to or composed of epithelium.


How does epithelial tissue do its job?

Epithelial tissues are used in multicellular organisms to protect areas of their bodies that come into contact with the external environment, so they are mostly found in skin and the gastrointestinal tract.

What is the difference between pseudoepitheliomatous hyperplasia and epithelial hyperplasia?

Type your answer here... Pseudoepithelimatous hyperplasia histologically mimics squamous cell carcinoma but its not in case of epithelial hyperplasia.Eg of former includes histoplasmosis,blastomycosis,Tb,Syphilis etc..


What is the difference between endothelium and mesothelium?

Endothelium is a type of epithelium that lines blood vessels and the heart, while mesothelium is a type of epithelium that lines body cavities such as the abdominal and thoracic cavities. Endothelium helps regulate exchange of substances between blood and surrounding tissues, while mesothelium mainly provides a protective barrier and lubrication for organs within body cavities.

What tissue is the walls of the alveoli composed of?

the walls of the alveoli are very thin but strong layers of elastic tissue lines with a single layer of flattened epithelium.


What is the difference between atypia and dysplasia?

Dysplasia is the sum of various disturbances of epithelial proliferation and differentiation as seen microscopically.Individual cellular features of dysplasia are called epithelial atypia

What the difference between striated and non striated muscles?

straited produces movements and unstraited do not. straited are multinucleated and unstraited are uni-nucleated. straited has straitions of regular white and black band and unstraited is simple and smooth. striated muscle are voluntary while non -striated muscles r involuntary.. striated muscle r control by nervous system while non - striated muscles are control by chemical control system . striated muscles show rapid action while non- striated muscles show slow n steady action of work :) :)


What is the difference between visceral muscle and skeletal muscle?

1) skeletal muscle is voluntary 1) visceral muscle is involuntary 2) it is striated . 2) it is non striated 3) highly organized muscle. 3) less organized muscle

What are the flattened cells important in protection that fit together like tiles?

Well, there lots of shapes, but three common forms are cuboidal shaped cells (which are like cubes), squamous cells (which are like cuboidal except flattened), and then there are columnar cells (which are shaped like columns).As for the flattened cells that are important for protection, this is clearly referring to squamous epithelial cells. Every lumen of our bodies has a layer of epithelium surrounding it, partly for protection. The cells of these layers can be a variety of shapes, but squamous is common. Skin, for example, is squamous epithelial tissue. And yes, these cells fit together like tiles, so their shape is very important to the barrier function they serve. Epithelial cells can form different kinds of junctions between each other. One type, called a 'tight junction', causes the cells to bind to each other extremely closely.
