What is the core of microvilli?
The core of microvilli is attached to the plasma membrane. It also contain a bundle of about 40 filaments of actin.
Inside microvilli you have actin, and inside cilia you have microtubules. Cilia are larger than microvilli, and cilia can be seen in the upper GI tract to beat away mucous which traps bacteria, virus, and other particles, microvilli is often seen in the intestines of the GI tract for nutrient absorption. Hope that helps!
What epithelial tissue lines the stomach and its microvilli and increase surface area for absoption?
In humans absorption takes place in the small intestines. In the small intestines are tiny structures called villi. Each villi has microvilli. These villi increase the surface area for absorption. Inside a microvilli, there is a network of capillaries and lacteals. Lacteals absorb amino acids and transport it to the liver via the subclavian vein which leads into the back of the neck, from there it gets distributed to the rest of the body. Back…
