Question

Most of the fat digestion occurs in
a) Rectum
b) Stomach
c) Duodenum
d) Small intestine

Answer 1

Hint: The digestive tract divided into different parts and every part has its function in digestion of different food constituents.

Complete step-by-step answer:

1. To solve this question, we have to know about the different parts of the digestive tract first. The digestive tract involves the break-down of food into simple components. The mouth, esophagus, stomach, small intestine, large intestine, and anus are the hollow parts. The solid organs involve the liver, gallbladder, and pancreas. The small intestine separated into duodenum, jejunum, and ileum and the large intestine is separated into appendix, colon, cecum, and rectum. Every part works together to complete the digestion process.
2. Now, let us find the solution from the given options
   The rectum is the lower part of our large intestine it involves in the storage of stool. It does not involve fat digestion.
3. Now, the stomach has digestive juices that get mixed with the food. It only digests the fat partially.
   The next is duodenum; it is the upper portion of the small intestine that collects the food from the stomach and starts the nutrient absorption. This part cannot digest fats alone.
   The small intestine is the part where the complete digestion takes place. The fat is mixed with pancreas and bile to breakdown completely.

Thus, the right answer is option D. i.e., Small intestine.

Note: The stomach digests the food partially. The complete digestion takes place in the small intestine. The duodenum is the upper portion of the small intestine where the food from the stomach is being received, and the rectum stores the executed part after the digestion.
