What sort of cells occur in the epithelium lining the villi and crypts of Lieberlukn and what are their function?
Enterocytes (absorptive cells) consist of many tightly packed microvilli over a plasma membrane that contains transport mechanisms for absorption and produces enzymes for the final step in digestion. Goblet cells are found on and between the villi on the crypt mucosa. These cells are responsible for the production and maintenance of the protective mucus blanket by synthesizing and secreting glycoproteins known as mucins. Enteroendocrine cells, often found in the lower part of the crypts, produce the hormones secretin and cholecystokinin. Paneth cells provide host defense against microbes in the small intestine. They secrete a number of antimicrobial molecules into the lumen of the crypt, thereby contributing to maintenance of the gastrointestinal barrier.
What is the function of an micro-villus in an animal cell?
Micro-villi are not in animal cells, they are on them. They are very tiny "fingers" that increase the surface area of the cell.
Why villi is suited for its function?
One reason that villi are suited to their function is because they have a large surface area to absorb nutrients from food to pass through to the bloodstream.
Why does the colon not have villi?
Because Villi is a way for the small intestinal to increase it's surface. thus providing more space and more cells for absorption(main function). The colon on the other hand,it's primary function is to propel feces to the rectum (though is does absorb water and salts and some vitamins) and there's no need to increase it's surface because doing so doesn't help achieving it's function.
What is the villi function?
Increase surface area for food
What is the function of villi cells in the intestines?
the villi vastly increases the surface area for the absoption of food.
Why do absorptive cells in the gastrointestinal wall have short life?
because absorptive cells are subjected to a harsh environment
How do the finger like structures relate to the function of the small intestine?
If you mean the hairs on the cells they are villi and micro-villi
