Rabbit GIT Flashcards
1
Q
what type of stomach does a rabbit have?
A
simple
2
Q
Where does most fermentation happen?
A
caecum
3
Q
is the abdominal cavity large or small?
A
large
4
Q
is its GIT long or short?
A
long
5
Q
how are rabbits unable to vomit?
A
well developed cardiac sphincter
6
Q
describe the small intestine of a rabbit
A
- pylorus easily compressed by the duodenum
- duodenum easily compressed by the liver
- at end of the small intestine there is a sacculus rotundus ( ileocecocolic junction)
- Honeycomb external appearance (because of large number of lymph follicles (ileocecal tonsil)
- ileocolic valve (from ileum to colon) opens into ampulla coli (enlarged part of colon) at the junction of ileum, colon and caecum. It controls movement of ingesta from the ileum into the sacculus
7
Q
what part of the small intestine is a common site for foreign body impaction?
A
terminal part of ileum
8
Q
what is the sacculus rotundus?
A
spherical thick-walled englargement at the junction between ileum, caecum and colon
9
Q
describe the large intestine of a rabbit
A
- highly developed
- caecum lies on the right-hand side of the abdominal cavity and is coiled
- it is coiled 3 times into gyral folds
- ends of caecum has vermiform appendix with lymphoid tissue
- Vermiform appendix and SR have B lymphocytes
10
Q
describe the rabbit colon
A
- Teniae and sacculations characterise colon
- divides into proximal (ascending
colon) and distal colon - ascending colon has 3 sections:
- starts at ampulla coli, has small protrusions called warzen
- 3nd section has segments and pastoral contractions that separate ingest into digestible particles
- 3rd section is fuses coli, thickened muscular section that is highly innervated and vascularised: its mucosal surface has goblet cells
- acts as a pacemaker- regulating passage of ingest into distal colon
- distal colon is think walled and contains hard faecal pellets
- cecotrophy
11
Q
wha is cecotrophy?
A
soft faecal pellet produced by rabbits that they eat to gain extra nutrients
