Under a microscope, stained sections of the pancreas reveal two different types of parenchymal tissue.[2] Lightly staining clusters of cells are called islets of Langerhans, which produce hormones that underlie the endocrine functions of the pancreas. Darker staining cells form acini connected to ducts. Acinar cells belong to the exocrine pancreas and secrete digestive enzymes into the gut via a system of ducts.

Differences between the pancreas of sheep and cow?
Same structures and functions, except that one is smaller than the other: i.e., a sheep's pancreas is much smaller than that of a cow.
What are the structures that add enzymes to chyme in the small intestine?
The structures that add enzymes to chyme in the small intestine are the pancreas and the intestinal mucosa. The pancreas secretes pancreatic enzymes such as proteases, lipases, and amylases into the small intestine to aid in digestion. Additionally, the intestinal mucosa produces enzymes to further break down nutrients for absorption.
What two structures add digestive juices for the breakdown of fat?

How can a perforating gastric ulcer come to damage the pancreas?
A perforating gastric ulcer can be fatal. The spewing of gastric acids can damage all organs that the acid comes into contact with. The pancreas is exceptionally susceptible to the acid both from the exterior and the interior as it is the first place the acid is directed to for elimination.

What structures form the stomach bed?
