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.
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.
