Detailed explanation-1: -Your stools get hard and dry when your colon absorbs too much water. Constipation symptoms can include stomach cramps and feeling tired. Constipation can cause other health problems, such as hemorrhoids (red, swollen veins in the rectum).

Detailed explanation-2: -After the excess water is absorbed, the remaining solid waste is called feces. Feces contain indigestible food substances such as fiber. Feces accumulate in the rectum, which is the third part of the large intestine. As the rectum fills, the feces become compacted.

Detailed explanation-3: -The correct timing of material through the large intestine is critical for the formation of healthy stool. If material is pushed through too quickly, not enough water is absorbed and the stool is left with a high water content, which results in diarrhea.

Detailed explanation-4: -By the time food reaches the large intestine, the work of absorbing nutrients is nearly finished. The large intestine’s main job is to remove water from the undigested matter and form solid waste (poop) to be excreted.
