The correct answer is c) cecum.
The cecum is a part of the large intestine and is responsible for the initial stage of digestion, specifically for absorbing some of the fluids and salts that remain after the intestinal digestion and absorption have occurred.
On the other hand, the salivary glands, gallbladder, and pancreas are considered accessory organs of digestion. They play crucial roles in aiding the digestion process:
- Salivary glands: These glands produce saliva, which contains enzymes that initiate the breakdown of carbohydrates as soon as food enters the mouth.
- Gallbladder: This organ stores and concentrates bile produced by the liver, which is essential for the emulsification and digestion of fats.
- Pancreas: The pancreas produces digestive enzymes that are released into the small intestine to help digest proteins, carbohydrates, and fats.
In summary, while the cecum is part of the digestive tract involved in the absorption of nutrients, it is not classified as an accessory organ of digestion like the others mentioned.
