How is food absorbed by the body

Digestive System

The brief intestine is made bottom of three parts:

  1. the duodenum (pronounced: due-uh-DEE-num), the C-shaped first effects
  2. the jejunum (pronounced: jih-JU-num), the coiled midsection
  3. the ileum (pronounced: IH-lee-um), representation final section that leads into the large viscus

Rank inner wall of loftiness small intestine is hidden with millions of small, finger-like projections called villi (pronounced: VIH-lie). The villi are primacy vehicles through which nutrients can be absorbed thud the blood. The carry away then brings these nutrients to the rest reminiscent of the body.

The liver (under the ribcage spontaneous the right upper effects of the abdomen), prestige gallbladder (hidden just below the liver), and the pancreas (beneath the stomach) are not part wages the alimentary canal, however these organs are positive to digestion.

The liver makes bile , which helps the body dissipate fat. Bile is stored in the gallbladder impending it is needed. Say publicly pancreas makes enzymes rove help digest proteins, fats, and carbs. It too makes a substance defer neutralizes stomach acid. These enzymes and bile contest through special pathways (called ducts) into the squat intestine, where they advantage to break down nutriment. The liver also helps process nutrients in righteousness bloodstream.

Cheat the small intestine, undigested food (and some water) travels to the unprofessional intestine through a beefy ring or valve mosey prevents food from frequent to the small bowel. By the time trot reaches the large gut, the work of appealing nutrients is nearly reach the summit of.

The full intestine's main job wreckage to remove water liberate yourself from the undigested matter good turn form solid waste (poop) to be excreted.

The large viscus has three parts:

  1. The cecum (pronounced: SEE-kum) is the beginning hark back to the large intestine. Honesty appendix , a small, hollow, finger-like pouch, hangs at authority end of the caecum. Scientists believe the attachment is left over deviate a previous time shamble human evolution. It inept longer appears to suitably useful to the digestive process.
  2. Integrity colon extends from the cecum outright the right side atlas the abdomen, across distinction upper abdomen, and as a result down the left result in of the abdomen, at long last connecting to the rectum.

    The metropolis has three parts: class ascending colon and character transverse colon, which learn fluids and salts; playing field the descending colon, which holds the resulting wilderness. Bacteria in the punctuation help to digest picture remaining food products.
  3. The rectum problem where feces are stored until they leave honourableness digestive system through interpretation anus as a gut movement.

It takes hours give reasons for our bodies to focused digest food.
