This information helps you understand the anatomy of the large intestine and its function.
quote of Dr. Ben Kim
The mucosal lining of your large intestine is lined with tiny pits that open into long, tube-like intestinal glands; these glands are lined with specialized cells that absorb water, and other specialized cells (goblet cells) that release mucous into your large intestine to lubricate your stools and to protect the lining of your large intestine against acidic substances and potentially harmful gases.
The specialized cells that absorb water from your waste materials are responsible for about 10 percent of the water that you absorb from the foods and beverages that you ingest; the remaining 90 percent is absorbed by cells that line your small intestine.
This 10 percent of water absorption in your large intestine amounts to anywhere between a pint and a quart of water, and represents a significant portion of your body’s daily intake of water. As water is absorbed from the waste material in your colon, so are some nutrients, mainly minerals like sodium and chloride.
It takes anywhere between three to ten hours for your large intestine to absorb enough water from waste material to turn it into solid or partially solid stools. Your stools consist mainly of water, mucous, fiber, old cells from your intestinal lining, millions of microorganisms, and small amounts of inorganic salts.
