The Large Intestine (colon)

  • 5 to 6 - foot-long muscular tube that connects to the rectum
  • last chance to process vitamins
  • protects against harmful bacteria.
29.

The colon
1. becomes full of stool, or feces
2. empties the waste into the rectum

The Rectum

32.

The Rectum

  • an 8-inch chamber that connects the colon to the anus.
  • receives stool from the colon
  • When anything (gas or stool) comes into the rectum, sensors send a message to the brain
33.

Should I stay or should I go?

34.

The brain and the rectum

  • The brain decides if the stool can be eliminated.
  • If it can, the sphincters (muscles) relax and the rectum contracts (loosens), expells waste.
  • If not, the sphincters contract (tightens) so that the feeling temporarily goes away.

The anus

37.

The Anus

  • last part of the digestive tract.
  • made of muscles and the two anal sphincters
  • muscles stop stool from coming out when it is not supposed to.
  • sphincter keeps us from "going" until we reach the restroom
38.

Wow! What an amazing, complex journey!
