The pancreas is a soft, elongated, flattened gland 12 to 20 cm in length. [4] [5] [6]
The adult gland
weighs between 70 and 110 g. The head lies behind the peritoneum of the posterior abdominal wall
and has a lobular structure. The pancreas is covered with a fine connective tissue but does not
have a true capsule. The head of the pancreas is on the right side and lies within the curvature of
the duodenum. The neck, body, and tail of the pancreas lie obliquely in the posterior abdomen, with
the tail extending as far as the gastric surface of the spleen
