Roughages, also known as fiber, are an essential part of a healthy diet and play an important role in the alimentary tract. Here are some of the functions of roughages in the alimentary tract:
-
Movement of food: Roughages help in the movement of food through the alimentary canal, from the mouth to the anus. They add bulk to the stool and maintain the normal passage of food through the entire alimentary canal.
-
Bowel movement: Roughages regulate bowel movement and reduce the risk of constipation and diarrhea. They help to prevent constipation and get rid of undigested food.
-
Water retention: Roughages help in retaining water in the body. They absorb water as they pass through the large intestine, which helps in easy excretion of the feces.
It is important to note that roughages do not provide any nutrients to the body, but they are essential to maintain a healthy diet. They are present in carbohydrates as well as proteins and can be found in foods such as apples, pears, grapes, cereals, leafy green vegetables, and other fruits and vegetables.
In summary, the role of roughages in the alimentary tract includes helping in the movement of food, regulating bowel movement, and retaining water in the body. Roughages are an essential part of a healthy diet and can be found in a variety of foods.
