 All right, the last bit of digestive histo is the pancreas. The pancreas are an accessory. The pancreas is done that multiple times today. The pancreas is an accessory organ that dumps digestive juices into the duodenum. That's why we're looking at it in terms of digestive histo, but it also has an endocrine function. And so there are islets of Langerhans that we will want to identify or pancreatic islets that dump hormone, glucagon, and insulin into the bloodstream. So let's take a look at the pancreas slide. Crystal clear, right? Awesome. So all pancreas slides are different and they're stained differently, and this is actually one that I really like. So you're going to look for really subtle but distinctive islands of tissue that are different in this scene, and that will help you figure out, like, where you are. Most of this we know is actually exocrine tissue. So you can assume that most of it, most of this is exocrine. This looks like maybe we have some blobs of stuff, maybe some blood vessels that are emptied out, maybe some fat. I don't know what those big open holes are. This looks like a blood vessel complete with blood in it. I'm just orienting you because I found my eyelid of Langerhans that I wanted. All of these things, do you see how they actually look like little round tubes? Even though the lumen of the tube isn't super clear, it looks kind of fuzzy and mushy in there, but it has a look and this looks different. That looks like an island in this mess and this is the endocrine structure. These are the exocrine structures. Oh, these might be ducts. Like from the assini, which is what these are, these exocrine structures are assini and they are dumping their digestive juices into ducts that are gathering and heading to the duodenum. It's possible. I'm actually not positive about that. All right, I don't know about you, but I'm tired. I'm almost caught up. Another lecture is coming like in a day. All right, so digestive histo, you did it. You rock. I'm going to go take a nap.
