In which part of the alimentary canal food is finally digested?
Open in App
Solution
The correct option is D Small intestine
The correct option is D:
Explanation of the correct option:
- Because it contains all of the enzymes required for the digestion of every type of food, the food is finally digested in the small intestine of the alimentary canal.
- For the emulsification (break down) of lipids, the intestine has a bile enzyme. It contains the enzymes pancreatic lipase and intestinal lipase, which aid in fat digestion at the end. It contains pancreatic amylase, which aids in carbohydrate digestion. It contains trypsinogen, which, when activated by the enterokinase enzyme, breaks down trypsin. The trypsin enzyme aids in protein digestion. It contains Erepsin, which aids in protein digestion.
- The following sections make up the small intestine:
- Duodenum: The small intestine's broadest, shortest, and most flexed section. It takes bile from the pancreas and is shaped like a C.
- Jejunum: It's the section of the small intestine in the centre.
- Ileum: It is the section of the small intestine that is the longest. It's finally open at the lowest section of the abdominal cavity, in the caecum.
Explanation of the incorrect option:
Option A:
- Gastric fluids kickstart protein digestion in the stomach. Pepsin and hydrochloric acid are the most common ingredients in these juices.
- After a period of time, a thick liquid known as chyme is generated, which enters the duodenum, where it is mixed with digestive enzymes from the pancreas and bile juice from the liver, before passing through the small intestine.
Option B:
- When food enters the mouth, it is mechanically digested by mastication (chewing), and it also becomes when it comes into contact with saliva.
- Saliva contains salivary amylase, a digestive enzyme that begins the digestion of starch in meals.
Option C:
- In the large intestine, where the pH is slightly acidic, water and minerals are reabsorbed back into the circulation.
Final answer: In the small intestine of the alimentary canal food is finally digested.
