Answer:
Digestion in Humans
During the process of digestion, food passes through a continuous canal inside the human body(from mouth to anus) and this canal is known as alimentary canal or digestive tract.
The canal is divided into various compartments namely – the mouth, food pipe(oesophagus), stomach, small intestine, large intestine and the anus.
Various glands secrete digestive juices for breakdown of food.
The digestive tract and the associated glands together constitute the digestive system.
The food is taken into the body through the mouth and the process is known as ingestion.
In mouth, the food is chewed and broken down into small pieces by teeth and is acted on by saliva secreted by salivary glands.
The food is swallowed and passed to the oesophagus(foodpipe) which is then pushed down to the stomach by movement of the wall of the foodpipe.
In stomach is acted on by hydrochloric acid(kills bacteria in food), mucous(protects lining of stomach) and digestive juices(breakdown the proteins into simpler substances) secreted by the inner lining of the stomach.
From stomach food passes to small intestine where bile juice digets the fats and pancreatic juice converts carbohydrates and proteins into simpler form.
In lower part of small intestine, carbohydrates get broken down into simple sugars, fats into fatty acids and glycerol, and proteins into amino acids.
The digested food is absorbed by villi and passed into the blood vessels.The undigested and unabsorbed food enters the large intestine
Large intestine absorbs water and some salts from the undigested food and the remaining waste goes into the rectum which is expelled out through the anus.
