Detailed explanation-1: -The digestive system breaks down food into nutrients such as carbohydrates, fats and proteins. They can then be absorbed into the bloodstream so the body can use them for energy, growth and repair. Unused materials are discarded as faeces (poo).
Detailed explanation-2: -After food leaves your small intestine, contractions push any food that remains in your digestive tract into your large intestine. Water, minerals, and any nutrients are then absorbed from your food. The leftover waste is formed into a bowel movement.
Detailed explanation-3: -If the food remains undigested and if is passed into the large intestine then the undigested waste materials are removed in the form of faecal matter from anus and rectum. This may show signs of diarrhoea.
