salivary glands
release saliva composed of: bicarbonate mucin water salivary amylase
Esophagus
Carries food from the pharynx to the stomach.
Stomach
Storage, mixing, breakdown of food. starts digestion of proteins. produces HCl, pepsinogen, intrinsic factor.
Esophageal Sphincter
valve that allows food to enter into the stomach
Pyloric sphincter
Valve that controls stomach emptying
Rugae
Wrinkles within the stomach that allow it to expand when needed
Rennin
enzyme produced by the stomach in newborns to curdle milk for better absorption and digestion
Goblet cells
produce mucous
G-Cells
Produce gastin
Chief Cells
produce pepsinogen
Parietal Cells
Produce HCl and intrinsic factor
Greater Omentum
overlays the stomach and produced lymphocytes. Also is where fat is deposited in older animals
Liver
Produce Plasma proteins, angiotensinogen, IGF-1, Process nutrients and maintain nutrient levels in blood, Degrade toxins, Produce bile
Gallbladder
Store and excrete bile
Pancreas
Produce Procarboxypetidase, pancreatic lipase, chymotrypsinogen, pancreatic amylase, trypsinogen, bicarbonate, insulin, glucagon
Small intestines
Produce carboxypeptidase, aminopeptidase, maltase, lactase, sucrase and bicarbonate
Duodenum
Receives bile, pancreatic secretions, chyme. Also produce bicarbonate from the Brunner’s glands. Digestion of proteins, carbohydrates, and fat
Jejunum
absorbs fatty acids, monosaccharides, amino acids, calcium and iron
Ileum
Absorbs water, electrolytes, bile salts, and vitamin B12.
Ileum
Absorbs water, electrolytes, bile salts, and vitamin B12.
Cecum
Microbial fermentation of starch and cellulose. Absorb volatile fatty acid, vitamins, and water.
Colon
Microbial fermentation of starch and cellulose
Rectum
Formation of droppings
Anus
exit for fecal material
