The cell extension that assists epithelial cells in absorption is called a microvillus. Microvilli are tiny, finger-like projections on the surface of epithelial cells, particularly in the intestines, that increase the surface area available for absorption. This enhancement allows for more efficient nutrient uptake from the lumen of the digestive tract. Collectively, these structures form a brush border that plays a crucial role in digestive processes.
What else can I help you with?
The epithelial cells that look like small cubes are called?
The epithelial cells that look like small cubes are called cuboidal epithelial cells. They are typically found in glands and kidney tubules where secretion and absorption take place.
What is the function of epithelial cell in animal cells?
Epithelial cells form protective barriers in the body, lining organs, cavities, and surfaces. They help to regulate the exchange of molecules and ions between different tissues, and act as a barrier against pathogens and harmful substances. Epithelial cells also play a role in absorption, secretion, and sensation.
Is villi an extension ofthe mucosal cell membrane?
Yes, villi are finger-like projections on the surface of the small intestine that increase its surface area for nutrient absorption. They are covered by a single layer of epithelial cells, which are the main cells involved in nutrient absorption in the intestine. So, while villi are not an extension of the mucosal cell membrane, they provide more surface area for these cells to absorb nutrients.
Does the epithelial cell absorb water?
Epithelial cells primarily function to form protective barriers and facilitate absorption of nutrients rather than directly absorb water. However, in certain tissues, like the intestinal epithelium, water absorption occurs alongside the absorption of nutrients through osmosis and active transport mechanisms. Additionally, in the kidney's collecting ducts, epithelial cells regulate water reabsorption under the influence of hormones like antidiuretic hormone (ADH). Thus, while epithelial cells can be involved in water absorption, it depends on their specific location and function within the body.
What tissue is microvilli and goblet cells associated with?
Microvilli are associated with the epithelial tissue lining the small intestine, where they increase surface area for absorption. Goblet cells are specialized cells found in the epithelial tissue of the respiratory and digestive tracts, where they secrete mucus to protect and lubricate the lining of these organs.
What forms a brush border extension of epithelial cells?
Microvilli form the brush border extension of epithelial cells in the small intestine and kidney. These microscopic finger-like projections increase the surface area of the cells, aiding in the absorption of nutrients and water.
What part of the cell is a slender extension of plasma membrane that increase its surface area?
microvilli
The type of epithelial cells most commonly associated with absorption is the small intestine is what?
The type of epithelial cells most commonly associated with absorption in the small intestine are simple columnar epithelial cells. These cells are equipped with microvilli, which increase the surface area for absorption, facilitating the uptake of nutrients. Additionally, goblet cells interspersed among them secrete mucus to aid in digestion. Overall, this structure enhances the efficiency of nutrient absorption in the small intestine.

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

What types of tissue can have have microvilli?
The types of tissue that can have microvilli are epithelial and endothelial tissues. Microvilli are small, finger-like projections on the surface of cells that increase surface area for absorption and secretion. They are commonly found in tissues involved in absorption and secretion functions, such as the lining of the intestines and kidneys.
Do epithelial tissue conduct impulses?
No, epithelial tissue does not conduct impulses. Epithelial tissue functions primarily in protection, secretion, absorption, and sensation. Nerve cells, or neurons, are responsible for conducting impulses in the body.
Compare an epithelial cell and a root hair cell?
Epithelial cells and root hair cells serve distinct functions and have different structures. Epithelial cells form protective layers covering surfaces and organs, characterized by tightly packed cells that regulate absorption and secretion. In contrast, root hair cells are specialized for nutrient and water absorption in plants; they have elongated projections to increase surface area and enhance uptake from the soil. While epithelial cells are involved in various bodily functions, root hair cells are specifically adapted for their role in the plant's root system.
