The pancreas is a dual-function gland‚ having features of both endocrine and exocrine glands. The part of the pancreas with endocrine function is made up of approximately a million[3] cell clusters called islets of Langerhans. Four main cell types exist in the islets. They are relatively difficult to distinguish using standard staining techniques‚ but they can be classified by their secretion: α cells secrete glucagon (increase glucose in blood)‚ β cells secrete insulin (decrease glucose in blood)

1. Describe the anatomic location of the pancreas relative to the other organs in the upper portion of the abdominal cavity. - The pancreas is about 6 inches long and sits across the back of the abdomen‚ behind the stomach and liver‚ leveled with the top of the small intestine and it also borders the liver‚ spleen and kidneys. The head of the pancreas is on the right side of the abdomen and is connected to the duodenum (the first section of the small intestine) through a small tube called the pancreatic

The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body’s cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar. Basic Anatomy: The pancreas is located behind the stomach and is surrounded by other organs including the small intestine‚ liver‚ and spleen. It is about six inches long and is shaped like a flat pear. The wide part‚ called the

The major part of the pancreas‚ called the exocrine pancreas‚ functions as an exocrine gland‚ secreting digestive enzymes into the gastrointestinal tract. Distributed through the pancreas are clusters of endocrine cells that secrete insulin‚ glucagon‚ and somastatin. These hormones all participate in regulating

The Pancreas The pancreas is probably one of the few organs that we really do not pay close attention to‚ but it is a very vital organ. The pancreas is a part of the digestive system. It is the largest organ in its system. It plays life sustaining roles in the regulation of food digestion and blood glucose levels. The anatomy of the pancreas helps us to understand each part and each section and how it pertains to the body. It is also very to study the physiology‚ because it tells us the functions

2014 You may be asking yourself‚ “What is pancreatic cancer?” Pancreatic cancer is a disease caused by malignant (cancer) exocrine cells in the head of the pancreas. (National Cancer Institute). The exocrine cells make up about ninety-five percent of all the cells in the pancreas. (American Cancer Society‚ 2014). Pancreatic cancer is also called exocrine cancer or pancreatic adenocarcinoma. (Mayo Clinic‚ 1998-2014). Pancreatic cancer is the fourth leading cause of cancer-related death

PHYSIOLOGY: Structure of the Pancreas The pancreas is an elongated organ that lies behind and below the stomach. This mixed gland contains both exocrine and endocrine tissues. The predominant exocrine part consists of grape-like clusters of secretory cells that form sacs known as acini‚ which connect to ducts that eventually empty into the the first portion of the intestine called duodenum. The smaller part of the gland consists of isolated islands of endocrine tissue known as islets of Langerhans
