Digestive System Flashcards
(30 cards)
Which compartment of a ruminant’s stomach is the most cranial compartment, and what is its function?
The reticulum.
The contraction of the reticulum pumps the food into the omasum and also towards the cardia part of the rumen for further regurgitation.
What is micelles?
Digested food containing fat in the intestinal lumen.
What enzyme is found in the saliva of pigs?
Amaylase
What is the function of bile salts?
Emulsification of fat.
List the substances that are produced in the rumen after microbial digestion or fermentation.
Volatile fatty acids (VFAs)
Carbon dioxide
Methane
Ammonia
Where does the most absorption take place in dogs and cats?
The small intestine,
Fat is carried to the general circulation by what?
Lymph
Name the organ that produces the hormones CCK and secretin.
The duodenum
What is the largest compartment of a ruminant’s stomach
The rumen
The maximum gastric juice is produced during what phase?
The gastric phase
Name the three phases that stimulate gastric juice secretion.
Cephalic phase
Gastric phase
Intestinal phase
What is the hardware disease or traumatic reticulitis in cows?
The ingestion of sharp objects like nails and wires by cows. The sharp objects lodge themselves in the reticulum and may penetrate the reticulum causing traumatic reticulitis.
Which animals do not have a gall bladder?
Horses
What is the effect of CCK and secretin on the stomach motility?
Decreases the stomach motility.
What is chylomicron?
The fat inside the intestinal cells containing triglycerides and free fatty acids.
Increased plasma concentration of which enzymes indicate acute pancreatitis?
Amaylase and lipase.
What is the main function of the rumen?
It helps in mixing the food contents and allows fermentation of fibrous food.
Name the organ responsible for bile production.
The liver.
What is milk fever?
A problem in high lactating cows after parturition where the cow is deficient in calcium because the onset of lactation draws on the calcium for milk production. This causes muscle spasms.
Bile is stored in what organ?
The gall bladder.
Name the small lymphatic vessels in the intestines that carry the fat to general circulation after absorption.
Lacteals
List all the enzymes produced by the pancreas.
Amylase, lipase, and trypsin.
Why is colostrum important for newborn animals?
It provides maternal antibodies.
Where does the cellulose digestion occur in horses?
In the cecum.
