Q

length of the stomach?

A

15-25cm (6-10 inches)

25
Q

Length of the esophagus?

26
Q

length of the alimentary canal of a cadaver?

A

30 ft/ 9meters

27
Q

length of the stomach when it is full? when it is empty?

A

full 4 liters
empty just collapses inward on itself, mucosa becomes rugae

28
Q

what are the regions of the stomach?

A

cardial region, fundus, body, pylorus

29
Q

what are the regions of the stomach?

A

cardial region, fundus, body, pylorus

30
Q

named for its position because it is near from the heart (region of the stomach)

A

cardial region

31
Q

expanded part of the stomach lateral to the cardial
region (stomach region)

32
Q

funnel-shaped of the stomach region

33
Q

it is the midportion stomach

34
Q

when the body of the stomach narrows it becomes ?

A

pyloric antrum

35
Q

continuous with the small intestine through the pyloric
sphincter or valve

36
Q

surrounds the cardioesophageal sphincter, through which food enters the stomach from the esophagus

A

cardial region

37
Q

the cardial region surrounds the?

A

cardioesophageal sphincter

38
Q

terminal part of the stomach

39
Q

the pylorus continuous to the small intestine by the?

A

pyloric sphincter or valve

40
Q

what is the wall of the stomach made up of?

A

obliquely arranger layer of muscularis externa

41
Q

a food that has been processed in the stomach?

42
Q

a simple columnar epithelium ,composed entirely of mucous
cells that produce a protective layer of bicarbonate-rich alkaline mucus that clings to the stomach mucosa and protects the stomach wall from being damaged by acid and digested by enzymes.

A

mucosa of the stomach

43
Q

mucosa of the stomach creates? and what is its purpose?

A

bicarbonate-rick alkaline mucus, protects the the linings or wall of the stomach from digestive enzymes and acid

44
Q

muscosa of the stomach is dotted with?

A

millions of deep gastic pits, leading to the gastric glands which makes up the secretion of the gastic juice

45
Q

produce intrinsic factor, a
substance needed for absorption of Vitamin B12 in
the small intestine. What cell?

A

stomach cell

46
Q

that produce protein digesting enzymes
mostly pepsinogens.

A

chief cells

47
Q

that is quite different from those secreted by the mucous cells in the mucosa

A

mucus neck cells

48
Q

produce a corrosive hydrochloric acid,
which make the stomach contents acidic and activates the enzymes, as in the conversion of pepsinogen pepsin by hydrochloric acid.

A

parietal cells

49
Q

produce local hormones such as gastrin, which are important in the digestive activities

A

enteroendocrine cells

50
Q

the chief cells produces?

A

protein digesting enzymes, mostly pepsinogens

51
Q

enteroendocrine cells produces purpose

A

local hormones, gastrin , important in the digestive activities

52
Q

chief cells produces? purpose?

A

protein digesting enzymes, pepsinogens

53
Q

parietal cells produces? purpose?

A

corrosive hydrochloric acid, making the stomach contents acidic and activates the enzymes

54
Q

stomach cells produces? purpose?

A

vit B12, aids in the absorption of the small intestines

55
Q

where does most digestive activity occur?

A

pyloric region

56
Q

a part of the where it is the greater
curvature

A

convex lateral surface

57
Q

is riddle-wig fat, which helps insulate cushion and protect the abdominal organs. It has also a large collection of the lymphoid follicles containing macrophages in defensive cells in the immune system—this is for the
protection of the gastrointestinal system.

A

greater omentum

58
Q

is the lesser curvature of the stomach

A

concave medial surface

59
Q

is a double layer peritoneum that
extends from the liver to the lesser curvature.

A

lesser omentum
