The longest section of the small intestines
ANSWERS: Ileum
Section of small intestine with only receptors for Vit B12 and bile salts
ANSWERS: Ileum
Junction from small intestine and large intestines
ANSWERS: Ileocecal valve
Two movements of the small intestines
ANSWERS: Mixing and propulsive movement
Mixing movement of small intestines
ANSWERS: Churns food but also slightly propels it
, Propulsive movements
ANSWERS: Primary push of the food through the alimentary canal towards
the anus but also spreads it out for allowing the digestive enzymes to mix
with it
Mixing movements
ANSWERS: Also known as the segmental contractions
Mixing movements main function
ANSWERS: To churn the chyme with intestinal enzymes and mechanically
break down some particles
Segmental contractions do what?
ANSWERS: Enhance the amount of time the chyme is exposed to the villi for
absorption
Peristaltic waves
ANSWERS:
Wave-like motions with a movement from the upper to the lower GI system
Large intestines
ANSWERS: AKA colon; begins at ileocecal valve and ends at anus
measurements of the large intestine
ANSWERS: Colon is 5-6 ft in length, 2.5-5.5 cm in diameter, largest at the
cecum
, Functions of the large intestines
ANSWERS: Fecal material formation, fluid absorption
What makes up fecal waste
ANSWERS: Bile pigment, mucus, undigested fats, cellulose, protein,
desquamated cells, electrolytes, water, undigested foods

odor of fecal materials
ANSWERS: bacteria
sections of large intestine in order
ANSWERS: cecum, ascending colon, transverse colon, descending
colon, sigmoid colon, rectum
What makes up gas in body
ANSWERS:
Swallowed air and bacteria in colon
Types of movement of large intestines
ANSWERS: Peristaltic movement, segmental movement, and mass movement
Peristaltic movement
ANSWERS: Pushes the fecal material through the colon
, Segmental movements
ANSWERS: Provides continuous motion that allows for continuous absorption
of water and electrolytes
Mass movement
ANSWERS:
Occurs when the left side off the colon contracts and thrusts the fecal
material into the rectum to be emptied through defecation, the evacuation
of fecal movement of bowel movement. An urge to defecate occurs when
the ingested food reaches the rectum, resulting in pressure changes and
voluntary sphincter reflex action
Stool consistency - ascending colon
ANSWERS: High volume and liquid-mushy (similar to ileostomy)
Stool consistency-transverse colon
ANSWERS: semi-solid; mush or paste consistency
Stool consistency- descending colon
ANSWERS: formed and solid
Stool consistency- sigmoid colon/rectum
ANSWERS: hard, solid stool
