Q

oral cavity

A
  • consumption
  • mastication- chewing
  • salivary glands produce saliva
    + digestive enzymes begin chemical digestion
    + lubrication of food

Q

esophagus

A

Q

stomach

A

storage of food

three parts
- fundus
- body: rugae- ridges from folding of wall alls stomach to expand
- pylorus- first part of small intestines
+ pyloric sphincter: opens/ relaxes food blows moves into duodenum

mucous linning

  • gastric juices
  • intrinsic factor
17
Q

lower Gi

A

small intestines
cecum
appendix
large intestines

18
Q

small intestines

A

longest section of Gi tract (20 feet)

function 
- finish digestion and begin absorption
19
Q

devision of small intestines

A

duodenum
jejunum
illeum
- muscular wall

mucous lining

  • place: circular folds
  • villi: cover plicae. expansion of surface area
20
Q

duodenum

A

c shape curve around pancreas

  • most chemical digestion occurs here
  • due to pancreatic ducts also most common place for ulcers
21
Q

jejunum

A

absorption of small nutrients

22
Q

ileum

A

final section

finishes absorption of vitamin b12, bile salts, any other product of digestion, water) appendix lives here

23
Q

cecum

A
  • last portion of small intestines, start of large intestines
  • small pouch: serves as reservoir
24
Q

appendix

A
  • wormlike structure, tubular
  • no important digestive function
  • incubator/ breeding ground for nonpathogenic intestinal bacterial
  • appendix
25
Q

large intestines (colon)

A

structure

  • larger in diameter than small intestines
  • 5 feet long
  • wall is composed of muscles to aid in peristalsis/ contraction to promote pooping
  • mucous membrane linning
function 
- absorption

division

  • ascending
  • transverse
  • descending
  • sigmoid
26
Q

heoatobillary structure

A

liver
gallbladder
ducts
pancreases

27
Q

liver

A

fills RUQ, expands into LUQ

function

  • secretes bile
  • removes broken-down Hgb from old RBC
28
Q

gallbladder

A
  • reservoir for bile

- concentrate stores bile: reabsorbing water and putting it back into blood stream

29
Q

ducts:

  • hepatic
  • cystic
  • common bile
A

hepatic: bile drain out of liver
cystic: bile enters and leaves gallbladder
common bile: drains into small intestines into duedem

30
Q

pancreas

A

behind stomach

function 
- secrete pancreatic enzymes
- digestion of carbs, proteins, lipids 
- neutralize acidity in gastric juices  
  \+ sodium bicarbonate: alkaline neutralizes acid in gastric juices

hormone production

  • insulin- beta cells; lowers glucose
  • glucagon- alpha cells; raises glucose
31
Q

altered nutrition

A

conditions include issues consuming digesting and absorbing food
- affected individuals are often underweight and vitamin deficient

32
Q

impaired elimination

A

conditions may be systems of another secondary condition or primary one

  • they may later neutron as well as impair elimination
  • diarrhea and constipation
