Observe the given part of the digestive system. What is it? What is its role during digestion? (AS1)

The given part of the digestive system is the large intestine. After the nutrients have been absorbed from the food in the small intestine, the digested mass reaches large intestine where water is reabsorbed from it. The remaining hard mass is then stored in rectum from where it is available to be passed out of the body through anus.
