GASTROINTESTINAL &
BILIARY TRACT
DISORDERS (22 HRS)
BLOCK III, M14 CLASS - KRCHNAUGUST 2015
FACILITATOR: M. ONYANGO
,OBJECTIVES
Recall the anatomy and physiology of the GIT
and related structures
Describe common manifestations in a patient
with GIT disorders
Describe the assessment of a patient suffering
from GIT disorders
Describe diseases/conditions of the GIT and
their management
Describe diseases/conditions of the biliary
tract and their management
, Review of GIT
Includes GIT and accessory digestive organs (teeth,
tongue, salivary glands, liver, gallbladder, and pancreas).
Digestion includes 6 basic processes:
ingestion,
secretion,
mixing and propulsion,
mechanical & chemical digestion,
absorption,
defecation
Histology: most of GIT, from deep to superficial;
mucosa,
submucosa,
muscularis,
Adventitia (serosa)
, Inervation
Enteric Nervous System (ENS) and
Myenteric orAuerbach's plexus , (muscularis):- regulates GI
tract motility
Submucosal or Meissner's plexus, (submucosa):- regulates GI
secretion
Autonomic Nervous System (ANS).
Parasympathetic fibers of the Vagus (X) & Spinal nerves :-
increase GI secretion & motility
Sympathetic fibers from thoracic & upper lumbar regions:-
decrease GI secretion & motility
Blood supply
Esophagus: esophageal arteries
Abdominopelvic organs: coeliac artery and thesuperior
andinferior mesenteric arteries
Drainage
Esophagus: esophageal veins
Abdominopelvic organs: portal vein
Lower rectum and the anus: internal iliac veins
