Teaching and Prevention
Digestion begins in ____
The mouth
Small intestine comprised of
duodenum
jejunum
ileum
junction between small intestine & L.I that helps to slow feces moving through and prevent backflow of feces
ileocecal valve
Absorption takes place in

Large intestine comprosied of
cecum. colon, rectum and anus
Motility of bowels is fast af in older adults. T or F

2 sphincters of anus
Internal sphincter –> Involuntary control
External sphincter –> voluntary control
Functions of Intestine
Motility
Absorption
Defecation (Valsalva’s Maneuver)
Two types of motility that assist w/ absorption & transportation through the full lengths of intestine
Segmentation
Peristalsis
alternation of contraction & relaxation of the smooth muscle that helps the slowing of passage of intestinal contents to allow digestion & absorption of contents
Segmentation
The speed of passage of intestinal contents effects
absorption
movement that propels contents across the intestines
peristalsis
What regulates the motility of bowels, where contents are constantly slowed down, but always in motion?
Autonomic Nervous system
Sympathetic- Slows down (Segmentation)
Parasympathetic- Speeds up
partially digested food + digestive juices
chyme
Stool is soft here _______
Stool becomes formed here___
Small Intestine

a breathing technique that involves forcefully exhaling against a closed airway; “Deep breath, bare down”
Valsalva maneuver

Soft, Formed
Cylindrical
Pungent- due to bacterial breakdown

Cellulose
High fiber + fluid rich diet results in this consistency of stool
Loose
