Location of the Pancreas The pancreas is located behind the stomach in the upper left abdomen. The central section of the pancreas is called the neck or body. The thin end is called the tail and extends to the left side.
Functions of the Pancreas A healthy pancreas produces the correct chemicals in the proper quantities, at the right times, to digest the foods we eat.
Exocrine Function: The pancreas contains exocrine glands that produce enzymes important to digestion. Endocrine Function: The endocrine component of the pancreas consists of islet cells islets of Langerhans that create and release important hormones directly into the bloodstream.
Pancreatitis Pancreatitis is inflammation of the pancreas that occurs when pancreatic enzyme secretions build up and begin to digest the organ itself. The pancreas secretes a magnificent battery of enzymes that collectively have the capacity to reduce virtually all digestible macromolecules into forms that are capable of, or nearly capable of being absorbed. Three major groups of enzymes are critical to efficient digestion:. Digestion of proteins is initiated by pepsin in the stomach , but the bulk of protein digestion is due to the pancreatic proteases.
Several proteases are synthesized in the pancreas and secreted into the lumen of the small intestine. The two major pancreatic proteases are trypsin and chymotrypsin , which are synthesized and packaged into secretory vesicles as the inactive proenzymes trypsinogen and chymotrypsinogen. As you might anticipate, proteases are rather dangerous enzymes to have in cells, and packaging of an inactive precursor is a way for the cells to safely handle these enzymes.
The secretory vesicles also contain a trypsin inhibitor which serves as an additional safeguard should some of the trypsinogen be activated to trypsin; following exocytosis this inhibitor is diluted out and becomes ineffective - the pin is out of the grenade. Once trypsinogen and chymotrypsinogen are released into the lumen of the small intestine, they must be converted into their active forms in order to digest proteins.
Trypsinogen is activated by the enzyme enterokinase , which is embedded in the intestinal mucosa. Once trypsin is formed it activates chymotrypsinogen, as well as additional molecules of trypsinogen. The net result is a rather explosive appearance of active protease once the pancreatic secretions reach the small intestine. Trypsin and chymotrypsin digest proteins into peptides and peptides into smaller peptides, but they cannot digest proteins and peptides to single amino acids.
A slender hollow tube inserted into the body to relieve a blockage. For example, pancreas cancers often grow into the bile duct as the bile duct passes through the pancreas. This can block the flow of bile and cause the patient to become jaundiced. In these cases the flow of bile can be reestablished by placing a stent into the bile duct, through the area of blockage. A maroon colored, rounded organ in the upper left part of the abdomen, near the tail of the pancreas.
This organ is part of your immune system and filters the lymph and blood in your body. It is often removed during the distal pancreatectomy surgical procedure.
A flat, scale-like cell. Although most pancreatic cancers look like ducts under the microscope, a small fraction look like squamous cells. A classification system that is used to describe the extent of disease. Clinicians use it to predict the likely survival of a patient. A long 20 foot tube that stretches from the stomach to the large intestine.
It helps absorb nutrients from food as the food is transported to the large intestine. There are three sections: the duodenum, the jejunum and the ileum. Due to its proximity to the pancreas, the duodenum is the section of the small intestine most often affected by pancreatic cancer. The use of high-energy waves similar to x-rays to treat a cancer. Radiation therapy is usually used to treat a local area of disease and often is given in combination with chemotherapy.
Able to be removed surgically. Usually this means that the cancer is confined to areas typically removed surgically. A malignant tumor that looks like connective tissues bone, cartilage, muscle under the microscope. Sarcomas are extremely rare in the pancreas.
A cancer in the organ where it started in. A primary cancer of the pancreas is one that started in the pancreas as opposed to a cancer that started somewhere else and only later spread to the pancreas. A forecast for the probable outcome of a disease based on the experience of large numbers of other patients with similar stage disease.
Importantly, making a prognosis is not an exact science. Some patients with poor prognosis beat the odds and live longer than anyone would have predicted. Steve Dunn's Cancer Guide has an excellent article on statistics and prognoses and stories of other cancer patients.
A thick ring of muscle a sphincter between the stomach and duodenum. This sphincter helps control the release of the stomach contents into the small intestine. A medical doctor specially trained to study disease processes. Pathologists make the microscopic diagnosis that is used to establish the diagnosis of cancer. Around the ampulla of Vater in the duodenum. The peri-ampullary region is comprised of 4 structures; the ampulla, the duodenum, the bile duct and the head of the pancreas.
It is sometimes difficult to tell which structure a tumor originated in. In such cases the diagnosis will be a peri-ampullary tumor. The biochemical study of plants; concerned with the identification, biosynthesis, metabolism of chemical constituents of plants; especially in regards to natural products.
An oblong organ located between the stomach and the spine. The pancreas secretes enzymes needed for the digestion of food and it produces hormones such as insulin and glucagon which help control blood sugar. Any treatment that reduces the severity of a disease or its symptoms.
Palliative care is often a part of the treatment plan for patients with advanced pancreatic cancer. A term used to describe certain tumors which grow in finger-like projections. Pathologists use this term to describe some precancerous lesions in the pancreas intraductal papillary mucinous neoplasm. An abnormal new growth of tissue that grows more rapidly than normal cells and will continue to grow if not treated.
These growths will compete with normal cells for nutrients. This is a general term that can refer to benign or malignant growths. It is a synonym for the word tumor. A medical doctor who specializes in the treatment of tumors.
Oncologists often treat patients with pancreatic cancer with chemotherapy. A surgically created opening in an organ that can also be referred to as an anastamosis. Sometimes when surgeons remove a segment of bowel they create an ostomy to allow for the bowel contents to exit the body.
A cancer that has spread from one organ to another. Pancreas cancer most frequently metastasizes to the liver. Chemotherapy and radiation therapy that is given to patients before surgery. Some centers feel that the use of neoadjuvant therapy improves local and regional control of disease and that it may make more patients surgical candidates. A cancer that has the potential of invading nearby tissues, spreading to other organs metastasizing and possibly leading to the patient's death.
Normal, round, raisin to grape-sized collections of lymphocytes white blood cells found throughout the body. Lymph nodes are connected to each other by lymphatic vessels. They normally help fight infection, but also are one of the first sites to which cancers spread.
In general, the spread of cancer to lymph nodes portends a worse prognosis for the patient. There are exceptions to this. A painless method for visualizing internal organs. A tube-like machine with a powerful magnet generates images of the inside of the body.
It does not involve the use of Xrays. The largest organ in the body, located in the right upper part of the abdomen. It performs many life-maintaining functions including the production of bile. The liver detoxifies the blood of drugs, alcohol and other harmful chemicals.
