Cards

Term
Two functions of the GI tract
Definition

Absorb fluid and nutrients

 

Provide temporary storage of waste

Term
The GI tract consists of:
Definition
Mouth, Esophagus, Stomach, Sm. Intestine, Lg. Intestine, Rectum, and Anus
Term
Purpose of the Mouth
Definition
Breaks up food enabling it to be swallowed. Chewing releases enzymes to help break down food.
Term
Purpose of the Esophagus
Definition
Transports food from mouth to stomach

powered by gravity and peristalsis
Term
What is Peristalsis
Definition
wave like movements of the digestive tract to move food along pathway
Term
What is NPO
Definition
Nothing By Mouth
Term
examples of clear liquid diet
Definition
water, tea, coffee, fat-free broths, fruit drink (no pulp) and hard candy
Term
What is clear liquid diet used for
Definition
post-op patients to determine GI function, acute illnesses, food intolerance, and to reduce fecal matter for diagnostic procedures
Term
examples of full liquid diet
Definition
everything on clear liquid plus milk, pudding, yogurt, ice cream, veggie juice, and smooth peanut butter
Term
Full liquid diet is used for
Definition
patients who cannot swallow food and a transition between clear liquid and regular diet
Term
examples of soft food diet
Definition
lean tender meats, scrambled eggs, mashed potatoes, cakes and puddings
Term
soft diet used for patients with
Definition
difficulty swallowing or chewing foods.
Term
ADA Diet
Definition
balance between diet, insulin, and exercise. low in carbs and sugar. High in fiber.
Term
Cardiac Diet
Definition
low fat and sodium. (fat no more than 30% of caloric intake).
Term
Food pyramid suggests
Definition
grains = 6 servings
veggies = 3 servings
fruits/meats/dairy = 2 servings
fats = in moderation
Term
describe a regular diet
Definition
variety of foods including fruits, veggies, whole grains and fat free or low dairy foods.

Low in added sugar and salt

fat intake between 20-35%

Food Pyramid
Term
Vegetarian Diet
Definition
primarily plant based foods.

uses meat alts (tofu, and soy burgers)

less fat and calories.
Term
three sections of the sm. intestine
Definition
duodenum, jejunum, ileum
Term
function of the folds of kerckring
Definition
prevent backflow of intestinal fluid
increase surface area
Term
pancreatic enzymes (active and inactive)
Definition
amylase, lipase (active)
trypsinogen, chymotrypsinogen, procarboxypeptidase, procolipase, prophospholipase(inactive)
Term
Sm. intestine is primary site of absorption (about 85%)
Definition
Term
Capillary networks of the villi carry blood to hepatic vein (80% of blood flowing from hepatic vein comes from stomach and sm. intestine)
Definition
Term
Three functions of nutrients
Definition
provide energy
provide structural material
regulate body processes
Term
what is the valsalva maneuver
Definition
voluntary contraction of the abdominal muscles during forced elimination which can cause changes in HR and rhythm
Term
what are the two types of carbs
Definition
simple

complex
Term
describe simple carbs
Definition
Sugars. water soluble.

produced naturally by plants and animals.

monosaccharide - single molecule
disaccharide - double molecule
Term
Describe complex carbs
Definition
starches and fibers
Term
what is a starch
Definition
insoluble polysaccharide
exists naturally in plants
Ex - grains, legumes, and potatoes
Term
What is a fiber
Definition
derived from plants
provides bulk to diet
helps the dig tract to function correctly and eliminate waste.
Term
Carb Digestion
Definition
Enzymes in carb digestion include salivary amylase, pancreatic amylase, maltase, sucrose, and lactose.

Desired end product of carb digestion is monosaccharide

all monosaccharides are absorbed in sm. intestine.
Term
proteins are made up of what?
Definition
Amino Acids.
Essential and Nonessential
Term
3/4 of the body's solids are proteins.
Definition
Term
What is a complete, partially complete and an incomplete protein
Definition
Complete - contain all essential AA (meats, fish, poultry, eggs, dairy)
partially complete - contain less than the essential AA and therefore cannot alone support growth.(gelatin)
incomplete - lack one or more essential AA. usually derived from veggies.
Term
Pepsin breaks down protein and digested in sm. intestine. stored via active transport to tissues and cells for cell structure. body cannot store excess AA
Definition
Term
Define Anabolism and Catabolism
Definition
Anabolism - building tissue
Catabolism - breakdown tissue

(nitrogen balance regulates this)
Term
Describe Lipids
Definition
organic, insoluble in water, soluble in alcohol.

fats - lipids in solid form
oils - lipids in liquid form
Term
fatty Acids (two types)
Definition
saturated - all carbon atoms filled to capacity
unsaturated - need more hydrogen atoms
Term
what are glycerides
Definition
simple lipids
Term
what are triglycerides
Definition
three fatty acids. account for more the 90% of lipids in foods and in the body.

saturated triglycerides - found in animals
unsaturated triglycerides - found in plants
Term
Describe Cholesterol
Definition
fatlike substance produced in both the body and in foods from animals. needed to create bile acids and to synthesize steroid hormones.
Term
End product of lipid digestion is glycerol, fatty acids, and cholesterol.
Definition
Term
What is a vitamin
Definition
an organic substance that cannot be manufactured by the body.
Term
water-soluble vitamin
Definition
C and B-complex
body cannot store these
Term
Fat-soluble vitamins
Definition
A,D,E,K
Term
Macrominerals include
Definition
calcium, phosphorus, sodium, potassium, magnesium.
Term
macrominerals are those that the body needs over 100mgs daily.
Definition
Term
microminerals are those that the body needs less than 100mgs daily.
Definition
Term
microminerals include
Definition
iron, zinc, copper, chromium, selenium
Term
What is metabolism
Definition
all biochemical and physiologic processes by which the body grows and maintains itself.
Term
BMR
Definition
rate at which the body metabolizes food to maintain the energy requirements of a person who is awake and at rest.

BMR = 24 X Weight(lbs)/2.2
Term
BMI
Definition
indicator of changes in fat stores and whether a person's weight is appropriate to height.

BMI = weight(kg)/height(m)2

obesity occurs when active teens become inactive adults w/o reduction in caloric intake.

calcium needed to maintain bone health
Term
developmental considerations: middle adult
Definition
portion control

postmenopausal women need calcium and vitamin d.

obesity a concern (decreased metabolic activity + sedentary lifestyle)

hypertension and diabetes a concern

lower cholesterol to maintain health
Term
developmental considerations: elderly
Definition
lower metabolic activity + sedentary lifestyle = fewer calories needed.

tooth loss and impaired sense of taste. ill fitting dentures and sore mouth a concern. diminished saliva production.

decreased social interaction and living alone contribute. anxiety, depression, and dependence on others also factor.
Term
Elderly Diet
Definition
fewer calories, limit sodium, reduce fat intake, adequate vitamin intake, high fiber, minimum # of servings of each food group.

physician ordered when diet and tolerance to food may change over time. usually starts with clear liquid and moves eventually to regular.

nasointestinal tube
Definition
short term nutrition support

inserted thru nose and into sm. intestine
