Answer

Process of Digestion in Human Being:

Digestion is the process by which the food we eat is broken down into simpler molecules that can be absorbed by the body. The process of digestion in human beings involves several organs and enzymes. The following is a flow chart with an explanation of the process of digestion in human beings.

1. Mouth:
The process of digestion begins in the mouth, where the teeth and tongue break down the food into smaller pieces. The salivary glands in the mouth secrete saliva that contains enzymes called amylase, which helps to break down carbohydrates.

2. Esophagus:
The food is then swallowed and enters the esophagus, a muscular tube that connects the mouth to the stomach. The muscles in the esophagus contract and relax to move the food down.

3. Stomach:
The food then enters the stomach, where it is mixed with stomach acid and enzymes that break down proteins. The stomach also churns the food, which helps to mix it with the digestive juices and break it down further.

4. Small Intestine:
The partially digested food then enters the small intestine, where it is mixed with digestive enzymes from the pancreas and bile from the liver. The enzymes break down carbohydrates, proteins, and fats, while the bile helps to emulsify fats so that they can be absorbed.

5. Large Intestine:
The remaining undigested food then enters the large intestine, where water is absorbed and the waste material is formed. The waste material then moves through the rectum and is eliminated from the body through the anus.

6. Enzymes:
Enzymes are a crucial component of the digestive process. They are produced by various organs such as the salivary glands, stomach, pancreas, and liver, and they help to break down the food into simpler molecules that can be absorbed by the body.

7. Absorption:
The nutrients that are broken down by the digestive process are absorbed by the small intestine and transported to the liver, where they are processed and distributed to the rest of the body.

8. Elimination:
The waste material that is not absorbed by the body is eliminated through the rectum and anus in the form of feces.

In conclusion, the process of digestion in human beings is a complex series of events that involve several organs and enzymes. It is a crucial process that allows the body to break down the food we eat and extract the nutrients that it needs to function properly.
