Question
Which of the following is the accessory organ of the digestive system?
- Pancreas
- Liver
- Salivary glands
- All of these
Hint:
Accessory organs are responsible for releasing their secretions for digesting food.
The correct answer is: All of these
- All of the above-mentioned organs, that is, the pancreas, liver, and salivary glands are the accessory organ for the digestive system.
- The accessory organs of the digestive system are those organs that are known for secreting substances, needed for the digestion of food, but the food doesn't actually pass through these organs during the process.
- The food first enters the mouth, where the salivary glands release saliva, which consists of salivary amylase that digests the food.
- It then moves to the lower part of the gut, where the secretions of the liver and the pancreas. The pancreas releases pancreatic amylase and the liver releases bile juice. Both of these secretions are released in the small intestine where the food is present.
- The food does not pass through these organs, instead, it just uses their secretions for digestion and absorption.
The small intestine is the main area for digestion and absorption.
