What are the main organs of the gastrointestinal (GI) system?
Gland, Larynx, Trachea, Esophagus, Diaphragm, Stomach, Spleen, Liver, Gallbladder, Transverse colon, Ascending colon, Small intestine, Cecum, Appendix, Rectum, Pyloric sphincter
Includes major organs involved in digestion and absorption.
What is the role of the parasympathetic nervous system in the GI tract?
Mainly excitatory, increases peristalsis
It stimulates digestive processes.
What is the function of the sympathetic nervous system in the GI tract?
Mainly inhibitory, decreases peristalsis
It inhibits digestive activity.
What is the enteric nervous system (ENS)?
Intrinsic nervous system that regulates motility and secretion in the GI tract
Composed of Meissner plexus and Auerbach plexus.
What are the two networks of the enteric nervous system?
Meissner plexus, Auerbach (myenteric) plexus
Meissner plexus is in the submucosa; Auerbach plexus is between muscle layers.
What is unique about circulation in the GI system?
Venous blood drains into the portal vein, perfusing the liver
This allows the liver to filter bacteria and toxins.
Which arteries supply blood to the GI tract?
Celiac artery, Superior mesenteric artery (SMA), Inferior mesenteric artery (IMA)
These arteries provide arterial blood to different parts of the GI tract.
