Alimentary Canal
-Passageway from mouth to anus.
-pharynx, esophogus, stomach, sm. intestine, lg. intestine, anal canal
salivary glands
produce saliva, initiates chemical change
Bolus
food after its been broken down through chewing and by saliva

passes into pharynx
peristalsis
action of the longitudinal and circular muscles located in walls of alimentary canal
stomach
-upper left quadrant
-holds 1 liter
-some chemical change happens
small intestine
-16 feet of tube
-most chemical change
-absorption of liquid and nutrients by capillaries
duodenum
-10 in. long
-first part of sm. intestine directly off stomach
-digestive juices emptied by accessory organs
jejunum
2/5 of of small intestine tube
ileum
last 3/5 of small intestine tube
large intestine
-mostly solid waste
-some absorption
peritoneum
-serous sac
-provides serous fluid to lubricate the organs within the abdominopelvic cavity
-organs lie outside the sac but project inward
functions of peritoneum
-decrease friction
-increase mobility
-provide pathway for vessels and nerves
definition and function of peritoneal reflections
-double layers or folds of peritoneum
-connect organs to body wall or eachother and provide passage way for nerves/vessels
visceral peritoneum
also called serosa

the layer of peritoneum that surrounds the organ
mesocolon
reflection of peritoneum that holds colon to the posterior abdominal wall
greater omentum
reflection of peritoneum hanging from greater curvature of stomach
typical digestive tube segments-- outer to inner
serosa or adventiva
muscularis
submucosa
mucosa
mucosa
lining of lumen (inner cavity)
submucosa
may contain mucous glands or vessels
fundus of stomach
pouches out and to the left
cardia
-area of entrance to stomach
-contains sphincter muscles to prevent backflow
chyme
partially digested, semiliquid form of food
rugae
folds withing the body of stomach covered by mucosa
pylorus
last portion of stomaach

contains sphincter muscle
What is digested in stomach?
alcohol
asprin

absorped by lining
plicae circulares
folds of mucosa and submucosa that increase surface area of sm. intestine for greater absorption
villi
-finger like projections of mucosa containing blood and lymphatic vessels
-only in sm. intestine
microvilli
projections from all epithelial (lining) cells

only in sm. intestine
veriform appendix
small tag of intestine extending from cecum in lower right quadrant
cecum
-pouch-like origin of colon
-found in lower right
-appendix extends from this
ascending colon
right side going up
traverse colon
traverse section
descending colon
left side of colon that goes downward
sigmoid colon
s-shaped section that leads to rectum
rectum
pelvic organ 3rd sacral level
teniae coli
continuous bands of muscle on colon
haustra coli
created because tenia coli are shorter than the tube
epiploic appendage
fat tags on colon
How long does food take to completely digest?
12-24 hours
accessory digestive organs
-connected to digestive tube by way of ducts that enter duodenum
-liver, gall bladder, pancreas
liver
-upper right quadrant
-largest internal organ
-produces bile
gall bladder
-inferior surface of liver
-stores bile created by liver
function and location of pancreas
-produces digestive enzymes
-upper left quadrant behind stomach
falciform ligament
holds liver to the anterior abdominal wall and divides it into left and right lobes
coronary ligament
reflection of peritoneum onto inferior diaphram attatches liver to diaphragm
Functions of Digestive organs
ingestion
peristalsis
mechanical breakdown (physical)
chemical breakdown
absorption
elimination of wastes
chemical breakdown
series of catababolic reactions that break down large carbs, lipids, and protein molecules ingested into smaller molecules usable by cells
mechanical breakdown
various physical movements that aid chemical breakdown
retroperitoneal
outside peritoneum
