    • The large intestine absorbs water from the chyme and stores feces until it can be egested.
    • Food products that cannot go through the villi, such as cellulose (dietary fiber), are mixed with other waste products from the body and become hard and concentrated feces.
    • The feces is stored in the rectum for a certain period and then the stored feces is eliminated from the body due to the contraction and relaxation through the anus .

  • Cholesterol Metabolism

    • Approximately 95% of the bile acids are reabsorbed from the intestines, and the remainder is lost in the feces.
    • Cholesterol is converted mainly into coprostanol, a nonabsorbable sterol that is excreted in the feces.
    • A cholesterol-reducing bacterium origin has been isolated from human feces.

  • Regulation of Water Output

    • Fluid can leave the body in several ways: urination, exretion (feces), and perspiration (sweating).
    • Fluid can leave the body in several ways: urination, excretion (feces), and perspiration (sweating).

  • Defecation Reflex

    • The internal and external anal sphincters, along with the puborectalis muscle, allow the feces to be passed by pulling the anus up and over the exiting feces in shortening and contracting actions.

  • Muscularis

    • In the colon, for example, the muscularis externa is much thicker because the feces are large and heavy, and require more force to push along.
    • Occasionally in the large intestine (two to three times a day), there will be mass contraction of certain segments, moving a lot of feces along.

  • Occult Blood

    • Fecal occult blood (FOB) refers to not-visibly-apparent blood in the feces that may indicate problems with the gastrointestinal tract.
    • Blood in the feces that is not visibly apparent is referred to as fecal occult blood (FOB).
    • A fecal occult blood test (FOBT) checks for hidden (occult) blood in the stool (feces).

  • Anatomy of the Large Intestine

    • The large intestine absorbs water from remaining indigestible food matter and compacts feces prior to defecation.

  • Digestive Processes of the Large Intestine

    • It also compacts feces, and stores fecal matter in the rectum until it can be defecated.
    • Bacteria make up most of the flora in the colon and up to 60 percent of the dry mass of feces.

  • Potassium Balance Regulation

    • On a zero K+ intake or in a person with K+ depletion there will still be a loss of K+ of 30-50 mmol/d in the urine and feces.

  • Onset, Duration, and Half-Life of Hormone Activity

    • The liver and kidneys are the major organs that degrade hormones with breakdown products excreted in urine and feces.
