  control

26
LARGE INTESTINE

• ANUS External opening
• Two anal sphincter
• 1. Interior involuntary
• 2. Exterior voluntary

27
DISORDERS

• Diarrhea NOT enough water absorbed by the colon.

28

• As part of the digestion process, or due to fluid
  intake, food is mixed with large amounts of
  water. Thus, digested food is essentially liquid
  prior to reaching the colon. The colon absorbs
  water, leaving the remaining material as a
  semisolid stool. If the colon is damaged or
  inflamed, however, absorption is inhibited, and
  watery stools result.

29
DISORDERS

• Constipation TOO much water absorbed by the
  large intestine.
• Make sure you drink plenty of water and eat more
  fiber

DISORDERS

• Hemorrhoids Large veins inflamed in rectum and
  anus
