FECAL ELIMINATION Flashcards
o longitudinal muscles are shorter than the colon
and therefore cause the large intestine to form
pouches
Haustra
o waste products leaving the stomach through the
small intestine and then passing through the
ileocecal valve
Chyme
o largely air and the by-products of the digestion of
carbohydrates
- Flatus
▪ involves movement of the chyme back
and forth within the haustra.
▪ aids in the absorption of water and
moves the contents forward to the next
haustra
Haustral churning
▪ Wavelike movement that propels
intestinal contents forward
▪ very sluggish and is thought to move the
chyme very little along the large intestine
o Peristalsis
▪ involves a wave of powerful muscular
contraction that moves over large areas
of the colon.
