- 1. Chapter 2: PancreasThe pancreas is a pinkish white glandular found in vertebrates near the stomach and small intestine. The pancreas is the second largest gland that is connected to the digestive tract, after the liver.The pancreas is one of the few organs that has an exocrine and an endocrine function. Exocrine glands are glands that secrete their products into ducts(duct glands). Endocrine glands are glands that secrete their product directly into the blood rather than through adduct.The pancreas exocrine function involves a secretion of bicarbonate and digestive enzymes into the small intestine. Its endocrine function involves the regulation of blood sugar levels by secreting the hormones insulin, glucagon, and somatostatin directly into the blood.
- 2. Chapter 2:(Continue)The endocrine portion of this organ consists of about 1 million islets of langerhans, amounting to only one to three percent of the organ weight. The majority of cells are exocrine and secrete one to three liters of digestive fluid per day.The pancreas is an important organ for digestion and the control of circulating levels of glucose. This organ is an excellent example of an intricate, well-tuned organ that functions in harmony with other parts of the body, providing a service to the body while receiving the nutrients and removal of wastes necessary for its survival. For example, interm of its function in the digestive system, it is one of several parts of the body that work together involving cooperative giving and receiving, including the stomach, intestines, liver pancreas, heart, brain and so forth.
