Question

Which of the following correctly represents the passage of food in our body?
(a) Mouth - stomach - food pipe - small intestine
(b) Mouth - food pipe - stomach - small intestine
(c) Mouth - stomach - small intestine - food pipe
(d) Mouth - small intestine - food pipe - stomach

Answer 1

Hint: Bile is produced by the liver. The inner lining of the stomach is protected by a layer which helps from being damaged by the acid. It is the process of digestion in which food once chewed in the mouth then goes down in the food pipe later in the stomach which passes down into the small intestine.

Complete answer:
Our digestive system is long, mouth to the rectum tube.
Food passes through this order in the digestive system:
Mouth - esophagus - stomach - small intestine - colon (large intestine)
In the food we eat a number of enzymes and gastric juices.
MOUTH - It makes use of amylase enzymes to bridge or mix food in the mouth by chewing saliva.
ESOPHAGUS – Esophagus is a tube which helps food with muscles and autonomous nerves move into the stomach.
STOMACH – Stomach contributes to the decomposition of food with acid and digestive enzymes. After breaking up food, the bottom of the stomach contracts to bind the process into the duodenum.
THE SMALL INTESTINE - Divided into three parts: Jejunum, Ileum and Duodenum
The pancreas releases an enzyme to assist the disintegration of fat, carbohydrates and proteins if food enters the duodenum through the stomach. The bile releases the gallbladder which helps break down the fat into a form that the intestine can easily absorb.
The small gut is bordered by small finger-like projections, called villi, that give the large absorption area.
In the small intestine absorption of nutrients, carbohydrates, fats, proteins take place.
THE COLON (LARGE INTESTINE) - Water absorption of salt and remaining carbohydrates and fats is carried out in the colon, which constitutes the last stage in the digestive system, and then transfers in the form of faeces.

Note:
The largest part of the digestive system is the stomach. It digests not just food, but stores it too. The BBC states that a little over a quarter (1 liter) of food is contained in the stomach at once. A person can eat a big meal that can be digested slowly over time thanks to the stomach design.
