Thank you for using the Jiskha Homework Help Forum. You need to be very specific when you post a question. Do you mean how fiber is used in the body when you consume it?

It seems that the text you provided after your question is not related to the topic of fiber. However, I can answer your original question, which is about the function of fiber in the body.

Dietary fiber, also known as roughage, is a type of carbohydrate that is not easily digested by the body. Unlike other carbohydrates, fiber cannot be broken down into sugar molecules, so it passes through the digestive system largely intact. The function of fiber in the body is primarily related to digestive health and regular bowel movements.

When you consume fiber, it adds bulk to your stools and helps to soften them, making them easier to pass. This prevents constipation and promotes regular bowel movements, which is important for maintaining a healthy digestive system. Additionally, fiber can help to regulate blood sugar levels, lower cholesterol levels, and contribute to a feeling of fullness, which can aid in weight management.

To get more detailed information about the function of fiber in the body, you can visit reliable health websites, such as eHealthMD (http://www.ehealthmd.com/library/fiber/FIB_body.html), which provides comprehensive information on fiber and its effects on the body.
