Pancreas Diagram
The pancreas, that somewhat look like the head of a golf club, does the job of producing digestive juices. It can be divided into 4 parts―the head, neck, body, and the tail. Bodytomy elaborates more on the anatomy of the human pancreas.
As a part of the digestive system, it functions as an exocrine gland secreting pancreatic juice into the duodenum through the pancreatic duct.
Blood circulation to the neck, body, and tail of the pancreas comes from the branches of the splenic artery, an offshoot of the celiac artery. The head of the pancreas receives blood from the superior and inferior pancreaticoduodenal artery, that moves along the border of the front and back surfaces of the head of the pancreas.
