ANATOMY

Detailed explanation-1: -Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.

Detailed explanation-2: -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-3: -The descending colon stores feces that will eventually be emptied into the rectum. The sigmoid colon contracts to increase the pressure inside the colon, causing the stool to move into the rectum. The rectum holds the feces awaiting elimination by defecation.

Detailed explanation-4: -In the large intestine, the chyme (partially digested food) from the small intestine is mixed with mucus and gut bacteria to form feces, digested waste material that is excreted. The large intestine acts as to concentrate and store fecal matter before it is eliminated via defecation by the anus.

Detailed explanation-5: -The primary function of the large intestine is to absorb water and salts from undigested food. Although bacteria are present in the large intestine to help break down the undigested food before it is egested via the anus, water and salt are the main nutrients reabsorbed in the large intestine.
