Flashcards in 2 Gastrointestinal System Deck (28):
1

oral cavity function

mechanical, chemical breakdown of food

2

esophagus function

food bolus propelled by peristalsis

3

stomach function

chemical digestion, storage

4

small intestine function

nutrient absorption

5

large intestine function

water, Cl-, Na+ absorption
HCO3-, K+ secretion

6

rectum function

empty until just prior to defecation

7

anus function

internal/external sphincters innervated by nerves that control continence

8

adolescent nutrition considerations

increased metabolic demands and muscle growth
(protein, iron, complex carbs)

15

pregnancy/lactation nutrition considerations

increased caloric requirements

16

older adult nutrition considerations

decreased metabolic rate

17

27

enema cramping?

lower bag to slow flow

28
