Chap 5 digestive system Flashcards
Defective enzymes aid the breakdown of complex nutrients :
Proteins–> amino acid
Sugars –> glucose
Fats –> fatty acids or triglycerides

Liver functions:
- Products bile
- Maintain normal blood glucose levels
- Manufacturers blood proteins necessary for clotting.
- Releases bilirubin, a pigment in bile
Excess= hyperbilirubinemia –> jaundice - Removes toxins and poison from blood
Absorption
Small intestine absorbs nutrients
Functions of pancreas:
- Endocrine function : secretes enzymes through duodenum for digestion.
- Exocrine function : secretes insulin from bloodstream to cells
Amino acids:
- Small building block of proteins;
- Released when proteins are digested.
Amylase:
Enzymes secreted by the pancreas and salivary glands to digest STARCH
Bile:
- Digestive juice made in the Liver and stored in the gallbladder;
- Composed of Bile pigments, cholesterol and Bile salts
- Breaks up large fat globules;
Bilirubin:
- pigment released by the Liver in bile.
- Too much results in hyperbilirubemia causing Jaundice and Scleral icterus.
Bowel
Intestine
Common bile duct:
- Carries bile from liver and gallbladder to duodenum;
- also called the Choledochus.
Emulsification:
Physical process of breaking large fat globules into smaller globules.
Enzyme:
- Chemical that speeds up reactions between substances;
- enzyme names end in -ase
Fatty acids:
- Substances produced when fats are digested;
- a category of lipids
Glycogen
Starch;
- Glucose is stored in the form of glycogen in the liver cells.
Hydrochloric acid:
- Substance produced by the stomach;
- necessary for digestion of food
Insulin:
Hormone produced by endocrine cells of the pancreas ( islets of Langerhans);
Transports sugar from the blood into cells and stimulates glycogen formation by the liver.
Lipase:
Pancreatic enzyme needed to digest fats.
Liver:
Stores: sugar, iron and vitamins ;
Secretes bile;
Produces blood proteins;
Destroys worn-out RBCs;
Filters out toxins;
Weighs about 2,5-3 lbs
Lower esophageal sphincter (LES)
Cardiac sphincter
Ring of muscles between the esophagus and stomach
Mastication
Chewing
Pancreas
Organ under the stomach;
Produces insulin and enzymes
Papillae ( papilla)
Small, nipple-like elevations on the tongue
Parotid gland:
Salivary gland within the cheek, just anterior to the ear.
Tuyen mang tai
Peristalsis
Rhythmic contractions of the tubular organs
Portal vein:
Large vein bringing blood to the liver from the intestines
Protease:
Enzyme that digests protein
Pyloric sphincter:
Ring of muscle at the end of the stomach, near the duodenum;
Opens when a wave of peristalsis passes over it.
Rugae:
Ridges on the hard palate and the wall of the stomach
Saliva:
Digestive juice produced by salivary glands;
Contains the enzyme amylase “mouth watering”.
Salivary glands:
Parotid, sublingual and submandibular glands.
