periodontal membrane (synonym) Ans✓✓-periodontal ligament (synonym)
stomach is not well adapted to absorb digestive products but it does absorb small
quantities of water, glucose, certain salts, alcohol and some lipid-soluble drugs
Ans✓✓-gastric absorption
transportation of digested end products from the lumen of the digestive tract to
the blood or lymph Ans✓✓-absorption
consists of the (1) mouth; (2) pharynx; (3) esophagus; (4) stomach; (5) small
intestine; (6) large intestine or colon Ans✓✓-alimentary canal (6 organs)
alimentary canal (synonym) Ans✓✓-digestive tube (synonym)
(1) mucosa; (2) submucosa; (3) muscular layer; (4) serosa Ans✓✓-alimentary
canal wall (4 layers deep to superficial)
lies between the rectum and the anus; the mucosa is folded to form anal canals
Ans✓✓-anal canal
location: the anal canal ends at the anus which opens to the exterior;

colon
nervous system that has 2 branches: (1) parasympathetic nervous system; (2)
sympathetic nervous system Ans✓✓-autonomic nervous system (2 branches)
(1) bile salts reduce the surface tension in fat globules and break them into
smaller droplets (emulsification); this greatly increases the surface area of the
fatty substance so lipases can digest it more effectively; (2) bile salts aid in the
absorption of fatty acids and cholesterol by forming complexes that are very
soluble in chyme and that epithelial cells can more easily absorb; the fat soluble
vitamins A, D, E, and K are also absorbed; lack of bile salts results in poor lipid
absorption and vitamin deficiencies Ans✓✓-bile salts in bile (2 functions)
removes damaged red blood cells and foreign substances by phagocytosis
Ans✓✓-blood filtering in liver
main region of the stomach located between the fundic and pyloric regions
Ans✓✓-body (location)
(1) grasp food; (2) tear food Ans✓✓-canines (2 functions)
