Q

Bile duct

A

conducts bile from the gall bladder into the small intestine

20
Q

appendix

also what size is it?

A

store lymph cells

21
Q

Small intestine

A
  • secrete enzymes that digest all energy yielding nutrients to smaller nutrient particles
  • cells of wall absorb nutrients into blood and lymph
22
Q

illeocecal valve

A

allows passage from small intestine to large intestine; prevents back flow from large intestine

23
Q

Pancreas

A

-manufactures
enzymes to digest all energy yielding nutrients

-releases bicarbonate to neutralize acid chyme that enters the small intestine

24
Q

Pancreatic duct

A

conducts pancreatic juice from the pancreas to the small intestine

25
Q

large intestine(colon)

A

reabsorbs/withdrawal water and minerals

26
Q

Parts of Small intestine

A
  • duodenum
  • jejunum
  • ileum
27
Q

Parts of Pancreas

A
  • ascending
  • transversing
  • descending
  • sigmoid
28
Q

bolus

A

-mouthful of food, chewed and swallowed, amount swallowed

29
Q

mastication

A

chewing mixing food with saliva

30
Q

What is 1000 times more sensitive than taste?

A

smell

31
Q

Muscular Action of Digestion

A
  • Peristalsis
  • Stomach Action
  • Segmentation
  • Sphincter Contractions
32
Q

What is peristalsis?

A

like toothpaste

-wavelike muscular contractions of GI tract that push contents along

33
Q

What types of muscles are used in digestion?

A
  • circular

- longitudinal

34
Q

Rate and Intensity of Contractions in Stomach and in Small Intestine

A
  • quick

- slower

35
Q

How are waves after a meal?

A

slow and continuous?

36
Q

How is the GI tract when empty?*

A

-quiet except for periodic bust of power waves

37
Q

what factors interfere with peristalsis?

A
  • stress
  • certain medications
  • medical conditions
38
Q

what are the three types of muscles?

A
  • circular
  • longitudinal
  • diagonal
39
Q

*The pyloric sphincter won’t unless what happens?

A

until chime id liquefied by gastric juices

40
Q

upper esophageal sphincter

A

-opens during a swallow

41
Q

lower esophageal(aka cardiac)

A

esophagus to stomach

42
Q

chyme

A

the semiliquid mass of partly digested food expelled by the stomach into the duodenum

43
Q

Appendix and function

A
  • located near end of small intestine and beginning of large intestine
  • stores lymph cells
  • make lymphs to store nutrients
44
Q

Muscular Action of Digestion

A
  1. Peristalsis
  2. Stomach Action
  3. Segmentation
  4. Sphincter Contractions
45
Q

Points on Segmentation

A

-Contraction of circular muscles in small intestine

-mix chyme
Promote contact with absorption cells

46
Q

Points on Sphincter Contractions

A

Sphincter Contractions

  • periodically open and close
  • prevents back flow of food
  • control pace of GI tract contents
