SUMMARY ACCORDING TO THE GUTS

• STRUCTURES:

1. Stomach
2. 1st two parts of the duodenum: Duodenal Cap and Descending Duodenum.
3. Liver
4. Gall Bladder
5. Pancreas
   

• ARTERIAL VASCULAR SUPPLY

1. Branches of the Celiac Trunk
   

• LYMPHATIC SUPPLY

1. Branches of the Celiac Nodes
   

• REFERRED PAIN: Occurs in the Epigastric Region.
• VENOUS RETURN: The portal vein.
• INNERVATION:

1. Parasympathetic: From Vagus nerve (C10). It is perivascular -- it follows the blood vessels.
2. Sympathetic: From the Greater Thoracic Splanchnic Nerves (T6-T10)

• STRUCTURES:

1. Third and fourth parts of duodenum: Horizontal and Ascending Duodenum.
2. Jejunum
3. Ileum
4. Cecum
5. Ascending Colon
6. First 2/3 of Transverse Colon

• ARTERIAL VASCULAR SUPPLY

1. Branches of the Superior Mesenteric Artery
   

• LYMPHATIC SUPPLY:
  

1. Branches of the Superior Mesenteric Nodes.

• REFERRED PAIN: Occurs in the Umbilical Region
• VENOUS RETURN: The Superior Mesenteric Vein.
• INNERVATION:

1. Parasympathetic: From Vagus nerve (C10). It is perivascular -- from the blood vessels.
2. Sympathetic: From the Lesser Thoracic Splanchnic (T9-T11,L1)

• STRUCTURES:

1. Distal 1/3 of Transverse Colon
2. Descending Colon
3. Sigmoid Colon
4. Rectum
5. Upper portion of anal canal.

• ARTERIAL VASCULAR SUPPLY

1. Branches of the Inferior Mesenteric Artery

• LYMPHATIC SUPPLY:
  

1. Branches of the Inferior Mesenteric Nodes.
2. Exception: The upper and lower rectum go to the Right and Left Common Iliac nodes, which then drains straight to the Lumbar Chain Nodes, and then to Thoracic Duct.
   

• REFERRED PAIN: Occurs in the Hypogastric (Suprapubic) region.
• VENOUS RETURN: The Inferior Mesenteric Vein.
• INNERVATION:

1. Parasympathetic: From Pelvic Splanchnic Nerves (S2-S4).
2. Sympathetic: From the Upper Lumbar Splanchnic (L1-L2)
