The pig is also called pig pancreas, and the pig is lying horizontally. That's a pig's pancreas, flat, about 12 cm long, pale pink, with some industrial white oil hanging on it. The shape of pig pancreas is irregular, close to human fat, but the color is dim, and there are granular lumps (pancreas) when squeezed hard.

Pig pancreas has two parts, one is pig pancreas, which is the exocrine gland of pig and produces pancreatic juice; Second, pig islets are like islands in the sea, which are organs made up of piles of cells in the pancreas. Islets are endocrine glands that produce insulin. Therefore, the pancreas is the only gland that is both an exocrine gland and an endocrine gland, and it is a special organ.

The exocrine fluid of porcine pancreas contains many digestive enzymes. There are also scattered island cell groups in the pancreas, called islets or Langerhans islands. Pancreatic islet β cells secrete insulin, which promotes hypoglycemia and hepatic glycogen synthesis. Pancreatic islet α cells secrete glucagon, which can promote the decomposition of hepatic glycogen.
