(a) Stomach
(b) Small intestine
(c) Large intestine
(d) Oesophagus

Answer 1

An alimentary canal is a pathway through which the food enters the body and the solid wastes get expelled. It consists of various parts which function differently and performs the process of digestion.

Complete answer:
The small intestine receives bile from the liver. The food is passed into the stomach which is located below the diaphragm and the cardiac stomach is connected with the oesophagus which is guarded by the cardiac sphincter and prevents the food acid from the stomach from entering into the oesophagus. The middle part of the stomach is the fundus and the pyloric stomach is connected with the duodenum which is guarded by the pyloric sphincter that prevents the food from the duodenum from entering the stomach. The small intestine is coiled and folded and the chyme from the stomach is pushed into the duodenum and The breakdown of food occurs in the small intestine. The undigested material is passed into the colon in the long intestine and it is stored in the rectum as faecal matters temporarily. This undigested food leaves the body through the anus by the process of egestion or defecation.

Additional information:
Stomach: The stomach is a muscular organ which is located on the upper abdomen and it helps in receiving food from the oesophagus. It helps with the digestion of food by secreting acids and enzymes. The digestive fluid in the stomach is hydrochloric acid which is formed by the stomach during the process of digestion and which functions in destroying the harmful microorganisms that are present in food particles. Hydrochloric acid helps in creating a medium of gastric juice which is acidic for the enzyme pepsin to digest the protein which kills the bacteria present in them.
Large intestine: Large intestine is the last part of the gastrointestinal tract which absorbs the water and the remaining waste material is stored in the form of faeces which gets removed by defecation and the Salt from the material that is not digested gets absorbed here.
Oesophagus: It is a tube that transports food from the pharynx to the stomach and begins in the neck. The food gets pushed in the oesophagus into the stomach with a series of muscular contractions and it initiates from the level of the sixth cervical vertebra which is behind the cricoid cartilage of the trachea.

So, the correct answer is 'Small intestine'.

Note:
About 2 pints of saliva is produced by an average human every day which is equal to about two cans of soda. The small intestine is 22-23 feet long whereas the long intestine is about five feet long only. The length of the human alimentary canal is 6-9 meters.
