Tick mark the correct answer in each of the following:
(a)Fat is completely digested in the
(i)stomach
(ii)mouth
(iii)small intestine
(iv)large intestine
(b)Water from the undigested food is absorbed mainly in the
(i)stomach
(ii)food pipe
(iii)small intestine
(iv)large intestine
(a)
Fat is completely digested in the Small intestine
The presence of fat in the small intestine produces hormones that stimulate the release of pancreatic lipase from the pancreas and bile from the liver, which helps in the emulsification of fats for the absorption of fatty acids.
Digestion of some fats can begin in the mouth, where lingual lipase breaks down some short chain lipids into diglycerides. However, fats are completely digested in the small intestine.
Fat is completely digested in the small intestine because it gets bile from the liver through the gallbladder, which is responsible for fat digestion.
Hence, Fat is completely digested in the Small intestine.
b: (iv) Large intestine
The large intestine is a long, thick tube that measures about 5 feet in length. Just under the stomach, it is found and coils around the small intestine’s upper and lateral sides. It absorbs water and comprises bacteria that facilitate waste breakdown to collect small nutrients.
Primarily in the large intestine, water from the undigested food is absorbed. It takes several hours for food to travel to enter the large intestine via the digestive track. There is a need to clean out the undigested food residues. When the goblet cells consume the access water from the food residue, it occurs in the large intestine.
