Defecated
In digestion, the unused parts of the food are eliminated from the body through a process known as defecation. This process involves the removal of solid waste that the body cannot digest or absorb. Here is an explanation of how this process works:

1. Digestive Process:
- When we eat food, it passes through the digestive system where it is broken down into nutrients that the body can use.
- The body absorbs these nutrients such as vitamins, minerals, proteins, and carbohydrates from the food.
- However, there are parts of the food that the body cannot digest, such as fiber and other indigestible substances.

2. Formation of Waste:
- These indigestible parts, along with other waste products produced during the digestion process, are formed into a solid mass known as feces in the large intestine.
- The feces consist of undigested food, bacteria, mucus, and dead cells from the lining of the digestive tract.

3. Elimination through Defecation:
- The feces are stored in the rectum until they are ready to be eliminated from the body.
- The act of defecation involves the expulsion of feces from the body through the anus.
- This process is controlled by the nervous system and the muscles of the rectum and anus.
In conclusion, defecation is a vital part of the digestive process as it helps the body get rid of waste material that it cannot use. It is important to maintain healthy digestion to ensure proper elimination of waste from the body.
