Alimentary canal - Answer begins in the mouth and ends in the anus
Accessory organs - Answer organs that function to assist with the digestive process are the
salivary glands, liver, gallbladder, and pancreas
Four layers of the GI tract - Answer mucosa, submucosa, muscle, serosa
Which nervous system controls the alimentary canal - Answer Autonomic nervous system
Which nervous system causes increase in digestive activity - Answer parasympathetic
nervous system
What does the sympathetic nervous system control - Answer sphincter muscles and
movement within the alimentary canal. This also assists with an inhibitory effect that provides
the ability to remain continent by sphincter control
Sphincter at end of esophagus to stomach - Answer LES- Lower esophageal sphincter
Four regions of the stomach - Answer Cardia, fundus, body, and pyloric
Sphincter from stomach to small intestine - Answer pyloric sphincter
First section past esophagus in stomach - Answer Cardia
Area in stomach where food is stored temporarily - Answer Fundus
The main region in the stomach - Answer The body
The area of stomach with large muscle that controls emptying into small intestine - Answer
Pyloric region
,What cells secrete pepsinogen? - Answer Chief cells of the stomach
What cells secrete hydrochloric acid in stomach? - Answer Parietal cells
What mixes to form Pepsin in the stomach? - Answer Pepsinogen and hydrochloric acid
How much gastic fluid is produced by the stomach daily? - Answer 2-3L
Measurements of small intestines - Answer 18-20 feet, 2.5 cm in diameter
Majority of what occurs in small intestines - Answer Chemical digestion, nutrient absorption
sections of small intestine - Answer duodenum, jejunum, ileum
What increases surface area of small intestines - Answer Intestinal villi
What is the purpose of intestinal villi? - Answer increasing surface area to absorb more
nutrients
The shortest section of the small intestine. - Answer duodenum
The longest section of the small intestines - Answer Ileum
Section of small intestine with only receptors for Vit B12 and bile salts - Answer Ileum
Junction from small intestine and large intestines - Answer Ileocecal valve
Two movements of the small intestines - Answer Mixing and propulsive movement
Mixing movement of small intestines - Answer Churns food but also slightly propels it
Propulsive movements - Answer 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 - Answer Also known as the segmental contractions
,Mixing movements main function - Answer To churn the chyme with intestinal enzymes and
mechanically break down some particles
Segmental contractions do what? - Answer Enhance the amount of time the chyme is
exposed to the villi for absorption
Peristaltic waves - Answer Wave-like motions with a movement from the upper to the lower
GI system
Large intestines - Answer AKA colon; begins at ileocecal valve and ends at anus
measurements of the large intestine - Answer Colon is 5-6 ft in length, 2.5-5.5 cm in
diameter, largest at the cecum
Functions of the large intestines - Answer Fecal material formation, fluid absorption
What makes up fecal waste - Answer Bile pigment, mucus, undigested fats, cellulose, protein,
desquamated cells, electrolytes, water, undigested foods
What exists in the colon and not in the small intestine and is responsible for odor of fecal
materials - Answer bacteria
sections of large intestine in order - Answer cecum, ascending colon, transverse colon,
descending colon, sigmoid colon, rectum
What makes up gas in body - Answer Swallowed air and bacteria in colon
Types of movement of large intestines - Answer Peristaltic movement, segmental movement,
and mass movement
Peristaltic movement - Answer Pushes the fecal material through the colon
Segmental movements - Answer Provides continuous motion that allows for continuous
absorption of water and electrolytes
Mass movement - Answer 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 - Answer High volume and liquid-mushy (similar to
ileostomy)
Stool consistency-transverse colon - Answer semi-solid; mush or paste consistency
Stool consistency- descending colon - Answer formed and solid
Stool consistency- sigmoid colon/rectum - Answer hard, solid stool
Functions of the GI system - Answer 1. GI motility
2. Provide digestive enzymes
3. Digest nutrients
4. Absorb nutrients
5. Expel waste and nutrients that were unused/unneeded
6. Maintain balance of fluids and electrolytes
Four stages of wound healing - Answer 1. Hemostasis
2. Inflammation (Defensive)
3. Proliferation
4. Maturation
Three types of wound closure - Answer 1. Primary
2. Secondary
3. Tertiary (Delayed primary)
GI ostomies are classified by what? - Answer 1. The segment of the intestine or colon used to
form the stoma
2. Continence status
What is a cecostomy used for? - Answer Antegrade enema or cecal decompression
Largest/widest segment of the colon - Answer Transverse
