Detailed explanation-1: -The large intestine’s main job is to remove water from the undigested matter and form solid waste (poop) to be excreted. The large intestine has three parts: The cecum (pronounced: SEE-kum) is the beginning of the large intestine.

Detailed explanation-2: -Small intestine. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.

Detailed explanation-3: -Absorption. The simple molecules that result from chemical digestion pass through cell membranes of the lining in the small intestine into the blood or lymph capillaries. This process is called absorption.

Detailed explanation-4: -Water waste removed in stools Once the small intestine has absorbed enough water to send throughout the body, it will pass the water along to the large intestine. When water reaches the large intestine, it will combine with solid matter to soften stool and aid digestion.

Detailed explanation-5: -The large intestine Water is removed and the waste (faeces) is stored in the rectum.
