PANCREAS
1. ANATOMY
The pancreas extends transversely
across the upper abdomen behind
the stomach.

The superior mesenteric vein and
artery lie just behind the
neck of the pancreas travelling downward.

The weight of the gland is between 75 and 125 gms.
-
The length is 10 to 20 cm.

The main pancreatic duct starts
at the tail of pancreas and
extends right a cross upto its
end at the sphincter of Oddi
travelling from left to right (Fig 22.1a).
-
The duct lies somewhat closer to the posterior
than to
the
anterior surface of the organ and its tributaries enter
at
right angles along its entire course.

In the head of the pancreas, the duct turns inferiorly to join
the common bile duct (Fig. 22.1b).

In most cases, the pancreatic duct is 3 to 4 mm in diameter.
