What is the function of epithelial cell in animal cells?
Epithelial cells have several functions. They line, protect, and form different glands. Epithelial cells have three shapes: flattened, cube, and elongated.
What types of tissue can have have microvilli?
Cells that line the small intestine are covered with microvilli for increased absorption.
Where to find reliable supplier for epithelial cells?
Epithelial cells are arranged in tightly packed layers that line the surfaces and cavities of tissues and organs throughout the body. Of the four major tissue types found in the human and animal body, epithelial cells are by far the most prolific. Epithelial cells also comprise key structures of exocrine and endocrine glands. The basic function of epithelial cells is to provide a protective layer for the organ they enclose, but they functions are diverse and include secretion, selective absorption, filtration, protection and detection of sensation.
What kind of a cell lines the small intestine and assembles fat?
The small intestine is lined with epithelial cells. These specialized cells have microvilli on their surface, which increase their surface area for absorption. These cells play a key role in the absorption of nutrients and fats from the digestive tract into the bloodstream.
New surface epithelial cells and epithelial cells lining the intestines are derived from where?
Stem cells
What forms a brush border extension of epithelial cells?
Microvilli

What is microvilli'?
Tiny projections on the free surface of some epithelial cells; increase surface area for absorption

What are renal epithelial cells?
Renal epithelial cells are the cells lining the renal tubules.

What is the function of an epithelial cells?
It lines the outside and inside of the body, such as skin. Functions of Epithelial Tissue * Protection: Epithelial cells protect underlying tissue from mechanical injury, harmful chemicals, invading bacteria and from excessive loss of water. * Sensation: Sensory stimuli penetrate specialized epithelial cells. Specialized epithelial tissue containing sensory nerve endings is found in the skin, eyes, ears, nose and on the tongue. * Secretion: In glands, epithelial tissue is specialized to secrete specific chemical substances such as enzymes, hormones and lubricating fluids. * Absorption: Certain epithelial cells lining the small intestine absorb nutrients from the digestion of food. * Excretion: Epithelial 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. * Diffusion: Simple 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). * Cleaning: Ciliated epithelium assists in removing dust particles and foreign bodies which have entered the air passages. * Reduces Friction: The 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 microvillus?
it is a thin protuberance present in great abundance at the surface of some epithelial cells, notably in the gut, thus increasing the surface area available for absorption
In adults new surface epithelial cells and the epithelial cells lining the intestine are derived from?
Stem Cells
Where are microvilli found?
Tiny "fingerlike" projections with actin filaents at the core of each to stiffen it and are not motile. Numerous microvilli form a brush border on cells of the small intestine/kidneys to allow absorption and secretion of large numbers of molecules.
