-
The first region of the small intestine is called the
duodenum
-
the esophagus empties into the
stomach
-
The only enzyme saliva acts on is
starches
-
ther are how many pairs of salivary glands?
3
-
the layer of tissue nearest the lumen of the smoach is the
mucosa
-
the complete digestive tube is how long?
27 ft
-
layers of digestive tract
- Inner: mucosa
- Imiddle: submucosa
- Omiddle: muscularis externis
- Outter: serosa
-
-
mouth
- recieves food and initiates the mechanical breakdown
- releases carbodrases
-
esophagus
- connecting the throat to the stomach.
- stuck between the spine and trachea so small region
-
large intestines
- colon, 5 ft
- ascending colon
- transverse colon
- decending colon
- ATD
-
partialperitoneal
lines the abdomin walls, adherent to the muscles
-
visceral peritoneal
- forms the
- serosa: thin outter layer of tissue of the digestive organs.
- holds organs together
-
mucosa
- produces digestive enzymes
- gobblet cells: secrete moucous that protects intestines.
- secretes hormones
-
submucosa
loose connective tissue
-
muscularis
double layer of tissue with muscle fibers
-
serosa
- visceral peritoneum
- holds organs together
-
when fibers thicken
sphincters are formed. they control the movement of the food
-
villi
produce digestive enzymes and absorb food that are digested
-
The layer with a thin peritoneal membrane is called the
serosa
-
The jejumn is part of the
small intestine
-
The appendix is found on the
cecum (bottom of colon)
-
salivary glands in the mouth
- parotid: largest in front of the ear
- submaxillary: located in the front of the mouth. secretes almase and mucos
- sublingual: floor of the mouth under tounge. secrets mucos
-
amylase
breaks down food into discharides
-
mucous
binds food together.
-
areas of the stomach
cardiac sphinctor, fundus, body, pyloric sphinctor
-
Glands of the stomach
in the mucosa, gastric glands produce gastric acids
-
muscle fibers of stomach
longways fibers and circular in order to mix and churn food
-
duodenal papilla
small raised area for digestive enzymes and bile secretions to empty into.
-
ileocecol valve
valve between small and large intestine
-
All protiens must be broken down into
amino acides before they can enter the blood
-
the secretion of some digestive juices is the result of
hormonal control
-
peristalsis refers to the muscular wave along the
digestive tract
-
some carb digestion
begins in the mouth
-
one of ones BMR refers to
basil metabolic rate
