Flashcards in Stomach (Abdomen #5) Deck (64):
1

what is the expanded part of the alimentary tract

the stomach

2

what is the stomach between

the esophagus and the small intestine

3

what is the shape of the stomach in most people

J

4

what can vary in people in regards to the stomach

the position and the shape

5

when the position and the shape of the stomach differs in the same person what is it due to

the diaphragmatic movements

6

what is the size of an empty stomch

slightly larger then the large intestine

7

how much food can the expanded stomach hold

2-3 L of food!!

8

what is the substance called that represent the food that is slightly liquidy that is found in the stomach

food-chyme

9

what is the size of a newborns stomach

a lemon

10

how much milk can a newborn stomach hold

30 ml

11

what does the stomach do to food

it mechanically prepares it for digestion and passage into the duodenum

12

what acts as a food reservoir and a food blender

the stomach

13

what is the chief function for enzymatic digestion

the stomach

14

what converts food into a semiliquid mixture

gastric juices

15

what passes fairly quickly into the duodenum

chyme

16

what serves as the 1st type of protection of the body for food coming in

the stomach

17

why is it that the stomach can protect from some bacteris

due to the high level of PH in the stomach

18

what thing needs a higher ph level in their stomach because they eat everywhere

wild animals

19

what are the four parts of the stomach

- cardia
- fundus
- body
- pyloric part

20

what is the part of the stomach that surrounds the cardiac orrifice

cardia

21

what is the superior dilated part of the stomach and is related to the left dome of the diaphragm

the fundus

22

what level does the superior part of the fundus reach?

level of 5th intercostal space

23

where is the cardial notch located

between the esophagus and the fundus

24

if the fundus is dilated by gas, fluid, or food where can you feel pain and why

you can feel it in the heart because the fundus is directly under the central tendon of the diaphragm which will the push up and apply pressure to the heart

25

what is known as the major part of the stomach and is between the fundus and the pyloric antrum

the body of the stomach

26

what is the funnel shaped outflow region of the stomach

the pyloric part

27

the wide part of the pyloric part

pyloric antrum

28

narrow part of the pyloric part

pyloric canal

29

what is the distal sphincter portion of the pyloric part

pylorus

30

what does pylorus do

controls the discharge of the stomach contents through the pyloric orifice into the duodenum

31

when does the stomach empty

when intragastric pressure overcomes the resistance of the pylorus

32

what can be used to further mix, digest, and absorb food

the small intestine

33

lesser curvature of the stomach

the shorter concave border of the stomach

34

angular incisure (notch)

this is the sharp indentation that indicates the junction of the body of the stomach and the pyloric part of the stomach

35

what forms the longer convex border of the stomach

the greater curvature

36

what protects the stomach from its own acid

the mucous layer

37

can you see the mucous layer in a cadaver

no only directly after birth

38

where can you see the gastric folds the best

toward the pyloric part and along the greater curvature

39

when do the gastric folds diminish

when the stomach fills

40

what is the mucous layer thrown into when stomach contracts

the gastric folds

41

what are the three layers in the stomach

- inercircular
- outer longitudinal
- oblique

42

where are the gastric folds not as big

near the fundus

43

where is the oblique layer deficent

near the lesser curvature

44

during swallowing a gastric canal forms where

along the lesser curvature

45

what forms (temporarily) because of the attachment of the gastric mucosa to the muscular layer which has no oblique layer

gastric canal

46

if you have bacterial liquid in the stomach as opposed to bacterial solid in the stomach what has a higher chance of formning

an infection

47

what is the stomach covered by

peritoneum

48

where is the stomach not convered in peritoneum

where the blood vessels run along its curvatures

49

the two layers of the lesser omentum extend around the stomach and leave its greater curvature as what

the greater omentum

50

what is the stomach related to anteriorly?

-diaphragm
- left lobe of liver
-anterior abdominal wall

51

what is the stomach related to posteriorly

the omental bursa

52

what forms most of the anterior wall of the omental bursa?

the posterior surface of the stomach

53

in what position does the stomach rest on the bed of the stomach

in the supine position

54

the bed of the stomach is formed by what

the structures that form the posterior wall of the omental bursa

55

tell me how the bed of the stomach is formed from superior to inferior

- left dome of diaphragm
- spleen
- left kidney and supradrenal gland
- splenic artery
- pancreas
-transverse mesocolon and colon

56

any fluid in the lesser sac will do what to the stomach

displace it forward

57

pancreatic pseudo cyst can do what to the stomavch

shift it anteriorly (usually visible)

58

what can happen in pancreatis

the posterior wall of the stomach can adhere to the part of the omental bursa that covers the pancreas

59

hiatal hernia?

this is a protrusion of the part of the stomach into the mediatinum through esophageal hiatus

60

hiatal hernia mostly occur in who

middle age people ( due to weakening of muscular part)

61

which hernia is less common and involves only the fundus extending through the esophageal hiatus

paraesophageal hiatal hernia

62

which hernia involves the part of the esophagus, the cardia, and the fundus, protruding through the esophageal hiatus

sliding hiatal hernia

63

how many babies have congenital diaphragmatic hernia

1 in 2200

64

what is the mortality rate for babes with congenital diaphragmatic hernia

76%
