Question

state the functions of following in the alimentary canal (a) liver (b) gall bladder (c) villi

Answer 1

Liver - The liver has two large sections, called the right and the left lobes. ... The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions.

Gall bladder -Its primary function is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver. The gallbladder is part of the biliary tract. The gallbladder serves as a reservoir for bile while it's not being used for digestion. ... The bile helps the digestive process by breaking up fats.

Villi - There, the villi and the microvilli increase intestinal absorptive surface area approximately 30-fold and 600-fold, respectively, providing exceptionally efficient absorption of nutrients in the lumen. There are also enzymes (enterocyte digestive enzyme) on the surface for digestion.
