Question

Answer

Oesophagus

It is a muscular tube that moves the partially digested food from mouth to stomach for further digestion. Hence, the Oesophagus is one part of the digestive system where no digestion occurs.

Answer

Because, the work of Oesophagus is to supply the food to the stomach by peristalsis and rhythmic movement. So there will be no digestion takes place.

Answer

Yes because it's just a food pipe through which food particles passes from mouth to stomach . Only peristalsis movement occurs due to movement of food particles .

Answer

Correct option is D because oesophagus is only a long tube extending from the pharynx to the stomach. There is no digestion take place in oesophagus only there is a movement called as peristalsis movement is there.

Answer

Oesophagus is a muscular to which contact mouth to stomach. food is transported by movement called peristalsis .  Oesophagus plays  no role in digestion.

Answer

Option D

Answer

The correct answer is option 'D', the esophagus.

The digestive system is a complex network of organs responsible for the breakdown and absorption of nutrients from food. It begins with the mouth and ends with the anus. Each organ in the digestive system plays a specific role in the process of digestion.

The esophagus is a muscular tube that connects the mouth to the stomach. Its primary function is to transport food from the mouth to the stomach. However, no digestion takes place in the esophagus.

To understand why no digestion occurs in the esophagus, let's look at the different parts of the digestive system and their respective functions.

1. Mouth:
- The mouth is responsible for the initial mechanical and chemical breakdown of food.
- The teeth chew the food, breaking it down into smaller pieces.
- Saliva, produced by the salivary glands, contains enzymes that begin the digestion of carbohydrates.

2. Stomach:
- The stomach is a muscular organ that further breaks down food mechanically and chemically.
- The stomach lining secretes gastric juices, including hydrochloric acid and enzymes, that help break down proteins.
- The churning movements of the stomach mix the food with gastric juices, creating a semi-liquid mixture called chyme.

3. Small Intestine:
- The small intestine is the longest part of the digestive system and is where most digestion and absorption of nutrients occur.
- The lining of the small intestine produces enzymes that break down carbohydrates, proteins, and fats.
- The walls of the small intestine contain tiny finger-like projections called villi, which increase the surface area for absorption of nutrients.

4. Esophagus:
- The esophagus is a muscular tube that connects the mouth to the stomach.
- Its main function is to transport food from the mouth to the stomach.
- The esophagus does not produce any digestive enzymes or perform any chemical or mechanical breakdown of food.

In conclusion, the esophagus is not involved in the process of digestion. Its role is solely to transport food from the mouth to the stomach.
