36
4 Pairs Of Salivary Glands?
Paratid gland
sublingual gland
mandibular gland
zygomatic gland
37
Pharynx function
Forms a cross-over between the digestive and the respiratory
systems
38
Eustachian (auditory) tube
Connects middle ear
39
Oesophagus
pharynx to the cardiac sphincter of the stomach
40
time it takes for bouls of food to be swollowed
15-30 seconds
41
Stomach location
cranial abdomen, slightly to the left side of the body.
42
4 main functions of the stomach?
Act as a reservoir for food.
Mix and break up the food
Begin protein digestion
Secretes gastrin into blood
43
Locations within the stomach?
cardiac, fundus, body, and
pyloric regions
lesser curvature: right
greater curvatures: left
44
Type of tissue stomach is lined with
simple columnar epithelium
45
5 main Gastric glands
Mucous and goblet cells
Parietal cells
Chief cells
Endocrine (D&G cells)
Enterochromaffin-like cells
46
Small Intestine role
enzymatic digestion absorption
47
Gall bladder
Stores bile produced by liver
48
4 layers of tissue within the wall of the small intestine?
The mucosa: simple columnar epithelium with villi
The submucosa
The smooth muscle
The serosa - outer layer
49
Name of glands in duodenum
Brunners gland
50
Name of glands located in the Jejunum and Ileum
Crypts of Lieberkühn
51
Function of Large Intestine
absorb water, vitamins and electrolytes
52
The structures of large intestine of the dog consists
Caecum
Ascending colon
Transverse colon
Descending colon
Rectum
Anus
53
Caecum
blind ending sac
54
Role of caecum in rabbits and Guinea pigs
contains bacteria
which breaks down cellulose
55
ileo-caecal valve
Controls passage of food from the ileum to the large intestines or colon
56
colon/large intestine main function
absorbs water
compacts waste
57
Function of goblet cells in large intestine
To produce Mucus to
aid the passage of faeces out of the rectum
58
Stercobilin?
a pigment derived from bile which gives faeces its
colour
59
Whats the largest gland in the body
Liver
60
Liver location
cranial abdomen between the stomach and
diaphragm
61
Function of the liver (9)
Produces bile
Regulates amino acids
Stores glucose (glycogen)
Stores fat (fat soluble vitamins)
Produces all clotting factors
Produces albumin and globulin
Detoxifies dangerous waste
Destroys old RBC
Stores Iron
62
falciform ligament
63
Liver Blood Supply
TOWARDS: hepatic artery (oxygenated)
hepatic portal vein
AWAY: The hepatic vein
64
The liver produces or synthesises
Glycogen
Cholesterol
Plasma proteins
Bile salts
Bile pigments
Bicarbonate
Haemosiderin
* Urea
* Erythropoietic factor (this is the substance which stimulates bone marrow to
make red blood cells)
65
2 bile salts

66
Name a bile pigment
bilirubin, biliverdin
67
what is urea?
68
what is Haemosiderin
69
function of Erythropoietic
stimulates production of blood cells in bone marrow
70
Gall Bladder function
Stores bile produced y live
71
The Pancreas
Endocrine: secrete insulin & glucagon into the blood.
(islets of langerhans)
Exocrine: secrete digestive enzymes that act upon carbohydrates, proteins and fats
72
Action of Amylase
breaks down starch to maltose
73
Action of lipase
breaks down fats to fatty acids and glycerol
74
Action of trysinogen
converted to active trypsin acts on protein
75

type of nitrogenous
waste (e.g urea)
77
pH of saliva
6.5
78
ph of gastric juice
1.5
79

80
what is an Enzymes
Protein molecules that increase the speed of chemical reactions in the
body
81
Villi
Hair like projections linging intestinal wall (increase surface area)
