Speech The Pancreas

Good morning ledies and gentlemen, Good morning my honoreble instructor, And good morning my friends. Thanks for the opportunity you given to me to standing in front of you to present my speech about “The Pancreas”, before I started, I wont to say thank you for God, because of his blessing we can meet here in this “english lesson”, in my speech I just wan tell you about pancreas in the general knowledge.

Ledies and Gentlemen, The pancreas is a gland organ that is located in the abdomen. It is part of the digestive system and produces important enzymes and hormones that help break down foods. The pancreas has an endocrine function because it releases juices directly into the bloodstream, and it has an exocrine function because it releases juices into ducts.
Enzymes, or digestive juices, produced by the pancreas are secreted into the small intestine to further break down food after it has left the stomach. The gland also produces the hormone insulin and secretes it into the bloodstream in order to regulate the body's glucose or sugar level.

The honorable ladies and gentleman , The pancreas is a 6- to 10-inch (18 to 25 cm) long organ located behind the stomach in the back of the abdomen. It is spongy and shaped somewhat like a fish that is extended horizontally across the abdomen. The head of the pancreas is the largest part and lays on the right side of the abdomen where the stomach is attached to the first part of the small intestine (the duodenum). It is here where the stomach empties partially digested food into the small intestine and this chyme mixes with the secretions from the pancreas. 
The tail or body of the pancreas - its narrowest part - extends to the left side of the abdomen next to the spleen. There is a duct that runs the length of the pancreas, and it is joined by several small branches from the glandular tissue. The end of this duct is connected to a similar duct that comes from the liver, which delivers bile to the duodenum.
There are two main types of tissue found in the pancreas: exocrine tissue and endocrine tissue. Most of the pancreas - about 95% - is exocrine tissue that produces pancreatic enzymes to aid digestion. A healthy pancreas makes about 2.2 pints (1 liter) of these enzymes every day. 

The remainder of the pancreas is composed of hundreds of thousands of endocrine cells known as islets of Langerhans. These grape-like cell clusters produce important hormones that regulate pancreatic secretions and control blood sugar.

Ledies and Gentlemen , A healthy pancreas is able to produce the right chemicals at the right times in the right quantities in order to properly digest the food we eat. After food enters the duodenum, the exocrine tissues secrete a clear, watery, alkaline juice that contains several enzymes that break down food into small molecules that can be absorbed by the intestines. These enzymes include:
·         Trypsin and chymotrypsin to digest proteins.
·         Amylase to break down carbohydrates.
·         Lipase, to break down fats into fatty acids and cholesterol.
The endocrine portion of the pancreas, or islets of Langerhans, is composed of several cells that secrete hormones directly into the bloodstream. Insulin is a hormone secreted by pancreatic beta cells in response to a rise in blood sugar. The hormone also moves glucose from the blood into muscles and other tissues so they can use it for energy. In addition, insulin helps the liver absorb glucose, storing it as glycogen in case the body needs energy duringstress or exercise.
Glucagon is a hormone secreted by pancreatic alpha cells when there is a decrease in blood sugar. Its primary job is to cause glycogen to be broken down into glucose in the liver. This glucose then enters the bloodstream in order to restore the level to normal.

Ladies and Gentlemen all, the pancreas is a very important organ in our body, therefore we must maintain in order to stay healthy and function properly with, balanced diet and avoiding smoking and excessive drinking will help keep the pancreas healthy and functioning.
Ok ladies and gentlemen that's all about pancreas. Thank's for your attention to listening my speech, and I'm sorry if that some bad words thank you.
