Alimentary Canal: Structure and Function
The alimentary canal is a long tube-like structure that extends from the mouth to the anus. It is the pathway through which food travels during the process of digestion. The organs of the alimentary canal work together to break down food into smaller molecules that can be absorbed by the body.
Order of Organs:
The correct order of organs through which food travels in the alimentary canal is as follows:
i) Mouth, Oesophagus, Stomach, Small Intestine, Large Intestine, Rectum.
Explanation:
1. Mouth: The process of digestion begins in the mouth. Food enters the mouth and is chewed by the teeth. Saliva, produced by the salivary glands, mixes with the food to form a moist bolus, making it easier to swallow.
2. Oesophagus: After being chewed and mixed with saliva, the food travels down the oesophagus, which is a muscular tube connecting the mouth to the stomach. The walls of the oesophagus contract in a wave-like motion called peristalsis, pushing the food towards the stomach.
3. Stomach: The food then enters the stomach, a muscular organ that churns and mixes the food with gastric juices. These gastric juices contain enzymes and acids that further break down the food. The stomach also stores the partially digested food until it is ready to be released into the small intestine.
4. Small Intestine: From the stomach, the partially digested food enters the small intestine. The small intestine is the longest part of the alimentary canal. It is here that most of the digestion and absorption of nutrients take place. The inner walls of the small intestine have tiny, finger-like projections called villi, which increase the surface area for absorption.
5. Large Intestine: After passing through the small intestine, the undigested food, along with water and waste products, enters the large intestine. The primary function of the large intestine is to absorb water and electrolytes from the remaining food, forming feces.
6. Rectum: Finally, the feces are stored in the rectum until they are eliminated from the body through the anus during the process of defecation.
In conclusion, the correct order of organs in the alimentary canal is mouth, oesophagus, stomach, small intestine, large intestine, and rectum. Each organ plays a vital role in the process of digestion and absorption, ensuring that the body receives the necessary nutrients while eliminating waste products.
