Place the following events in sequence: A) Food enters your large intestine; B) Food enters your small intestine; C) Food enters
Anarel [89]

Answer:

The correct sequence is

1st step- Option C

2nd step- Option B

3rd step- Option A

Explanation:

Initially, when a person swallows the food, it goes into the stomach through a muscular type of tube which helps in the transportation of food items and liquids from the mouth into the stomach, which is commonly known as the esophagus.

After passing through this tube and reaching the stomach, the liquid and food items mix up with the juice that it produces, and eventually releases its particles into the small intestine. These transported particles are known as chyme.

As the food particles reach the small intestine, its muscles allow the food particles to mix up with the digestive juices that are released from the organs namely liver, pancreas, as well as the intestine and helps in the proper digestion of the food. The walls of the small intestine extracts the nutrients that are digested into the bloodstream, where the blood supplies the nutrients into the remaining parts of the body.

After the food is digested and nutrients are absorbed into the body, the remaining waste products or undigested particles are transported to the large intestine, where it extracts the water and converts the waste particles into the stool, which are later eliminated from the body.

Thus, the correct sequence is arranged above.
