Study this deck
Three main finctions of the digestive system
Digestion, Aborption, Elimination
Digestion
conveting ingested nutrients into smaller conponets
Absorption
Moving nutrients from the digestive tract into the body
Elimination
removing undigested material from the body
The innermost layer, serous membrane, contact with abdominal organs
visceral peritoneum
The outer layer, serous membrane lining, abdominopelvic cavity
parietal peritoneum
The subdivision, peritoneum, contains fat and hangs over the front of the intestines
greater omentum
The subdivision,peritoneum extending between stomach and liver
lesser omentum
The fan-shaped portion, peritoneum contains the vessels and nerves supplying the intestine
mesentery
The subdivision, peritoneum, extends from the colon to posterior abdominal wall
mescolon
The digestive tract layer in contact with the intestinal contents
mucosa
The visceral peritoneum attached to the surface of a digestive organ
serosa
The layer of connective tissue beneath the mucous membrane in the wall of the digestive tract
submucosa
The layer of the digestive tract wall that is responsible for peristalsis
muscularis externa
Type of epithelial tissue lining the esophagus
squamous epithelium
The type of epithelial tissue lining the stomach
simple columnar epithelium
Rhythmic contactions of the circular muscle layer that mixes food with digestive juices
segmentation
A wave of muscular contacion that propels food rapidly down the digestive tract
peristalsis
The valve between the distal end of t he stomach and the small intestine
Pyloric sphincter
The structure that covers the opening of the larynx during swallowing
epiglottis
The structure that guards the entrance into the stomach
LES
The part of the oral cavity roof that extends to form the uvula
soft palate
The final and longest section of the small intestine
ileum
The section of the small intestine that receives gastice juices and food from the stomach
duodenum
The mixture of gastric juices and food that enters the small intestine
chyme
Folds in the stomach that are absent if the stomach is full
rugae
The part of the large intestive just proximal to the anus
rectum
The small blind tube attached to the first part of the large intestine
vermiform appedix
The sphincter that prevents food moving from the large intestine into the small intestine
ileocecal valve
Finger-like extensions of the mucosa in the small intestine
villi
A blind-ended lymphatic vessel that absorbs fat
lacteal
bands of logitudinal muscle in the large intestine
teniae coli
The portion of the large intestine that extends across the abdomen
transverse colon
The most proximal part of the large intestine
cecum
The process of chewing
mastication
The act of swallowing
degluition
The gland that secrets bicarbonate and digestive enzymes
pancreas
An organ that stores nutrients and releases them as needed into the bloodstream
liver
The accessory organ that store bile
gallbadder
The salivary glands that are inferior and anterior to the ear
parotid glands
Glands found just under the tongue that secrete into the oral cavity
sublingual glands
A substance that emulsifies fat
bile
The form in which glucose is stored in the liver
glycogen
A waste product produced from the destrction to RBC
Bilirubin
A waste product synthesized by the liver as a result of protein metabolism
urea
The duct connecting the hepatic duct to the gallbladder
cystic duct
The duct that connects to the pancreatic duct
common bile duct
The duct that carries bile from both lobes of the liver to the common bile duct
common hepatic duct
An enzyme that acts on a particular type of disaccharide
maltase
A substance (not an enzyme) released into small intestine that neutralizes the acidity in chyme
sodium bicarbonate
A substance that disgest DNA
muclease
A pancreatic enzyme that splits proteins into amion acids
trysin
an enzyme secreted into the stomach that splits proteins into amino acids
pepsin
The splitting of food molecules by the addition of water
hydrolysis
The nutrient is usually ingested in the form of triglycerides
fat
The nutrient type that is patially digested by gastric juice
protein
This enzyme digest fat
lipase
Digested carbohydrates are absorbed into lacteals
false most digested fats are absorbed into lactreals
Villi are small extensions of the plasma membrans of individual intestineal cells
false, villi are folds in the mucose, each composed of many cells
A hormone released from fat cells that inhibits appetite
leptin
a duodenal hormone that stimulates insuline release
gastric-inhibitory peptide
a hormone that stimulated the secreation of gastric juices and increase stomach motility
gastrin
An intestinal hormone that causes the gallblasser to contract releasing bile
Cholecystokinin (ckk)
a duodenal hormone that controle bicarbonate production in the pancreas
secretin
A gastric hormone that stimulates hunger
ghrelin
a pancreatic hormone that inhibits hunger
