binds jejenum and ileum of small intestine to abdomen wall
bind transverse colon and sigmoid of large intestine to posterior abdominal
what are 6 basic functions of digestive function?
mixing and propulsion-mix food and secretions and propel them toward the anus
defocation-digested materials that were nto absrobed leave body through anus
Function of Esophagus
tube that transports food from pharynx to stomach
upper esophageal sphincter
passage of food from laryngopharynx into esophagus
whats the purpose of the elevations of the larynx?
allows sphincter to relax and lets the blous to enter esophagus
lower esophageal sphincter
relaxes during swallowing and allow bolus to pass from esophagus into stomach
what does the stomach connect ?
esophagus to duodenum
what are 4 main regions of stomach?
cardia, fundus, body, pylorus
2 parts of the pylorus:
: connects to body of stomach
: leads into duodenum

what is the largest internal orgam?
functions of the liver :
of glycogen and vitamins and minerals
activation of vitamin D
Ex of liver functions
processing drugs and horomone
what are 3 components of the liver
-small ducts b/w hepatocytes
3. hepatic sinusoids
: capillaries- rows of hepatocytes
Describe the movement of bile:
right and left hepatic ducts unite and exit lover as common hepatic duct
common hepatic duct joins cystic duct to form common bile duct
bile goes to small intestine
describe blood supply to lvier:
hepatic portal system
- drains blood from dgestive organs, sends it to liver
hepatic artery and hepatic portal vein carry blood to liver sinusoids where oxygen, nutrients and toxic substance taken up by hepatocytes
blood leaves liver by hepatic veins
hepatic veins drain inferior vena cava
