vitamin b12
33
GI tract
mouth--> esophagus-->stomach-->small intestine-->large intestine-->rectum-->anus
34
circular and longitudinal muscles working together push intestinal contents along; rate and intensity of contractions vary; factors that may interfere with peristalsis
peristalsis
35
circular, longitudinal and diagonal muscles ; timing the release of chyme
stomach action
36
contractions of circular muscles in small intestine
mix chyme, promote contact with digestive juices and absorption cells
37
sphincter contractions
periodically open and close; control pace of movement of GI tract contents
38
a portion; with respect to food, the amount swallowed at one time
bolus
39
the semiliquid mass of partly digested food expelled by the stomach into the duodenum
chyme
40
fingerlike projections from the folds of the small intestine
villi
41
tiny hairlike projections on each cell of every villus that can trap nutrient particles and transport them into the cells
microvilli
42
in the _____ and cell membrane there are hundreds of different kinds of enzymes and pumps which recognize and act on different nutrients
microvilli
43
any nutrient molecule small enough to be absorbed is trapped among the ________, digested further by enzymes there, and then absorbed by cells
microvilli
44
small intestine has
large surface area (10 feet long)
45
what are absorption techniques
simple diffusion, facilitated diffusion, active transport
46
villi do what
select and regulate nutrients absorbed
47
microvilli do what
enzymes and "pumps"
48
person cannot speak or gasp because food lodged in the trachea blocks the passage of air.
choking
49
international sign for choking
heimlich maneuver
50
the contents of the stomach are propelled up through the esophagus to the mouth and expelled; sometimes muscular contractions will extend and carry contents of the duodenum.
vomit
51
body's adaptive mechanism
vomit
52
medical treatment for vomiting
might be dehydrated- get hydrated, or it may be self-induced-- bulemia
53
frequent, loose, watery stools
diarrhea
54
medical conditions of diarrhea
irritable bowel syndrome, colitis, celiac
55
treatment for diarrhea always begins with
rehydration
56
symptoms include straining during bowel movements, hard stools, and infrequent bowel movements

58
heartburn is the painful sensation a person feels behind the breast
gastroesophageal reflux
59
people who overeat or eat too quickly are likely to suffer from
indegestion
60
the muscular reaction of the stomach to unchewed lumps or to being overfilled may be so intense that it upsets normal peristalsis
indegestion
61
a lesion(a sore)
ulcer
62
a lesion in the lining of the stomach(gastric ulcer) or the duodenum of the small intestine(duodenal ulcers)

found to only a limited extent in meats and not all in plants
glycogen
67
stores (in liver and muscles) glucose for future use; many molecules linked together in highly branched chains
glycogen
68
the class of lipoproteins that transport lipids from the intestinal cells to the rest of the body
chylomicrons
69
contain the highest amount of triglyceride and are therefore the least dense
chylomicrons
70
made by enterocytes from lipids absorbed in the small intestine
chylomicrons
71

stevia
72
essential nutrient examples
Calcium, phosphorus, potassium, sodium, chloride, magnesium, and sulfate. Iron, iodine, zinc, chromium, selenium, fluoride, molybdenum, copper, maganese
73
Diet planning principles
Adequacy, balance, kcalorie(energy) control, nutrient density, moderation, variety
74
Food lists group foods according to what
Their energy-nutrient contents
75
