Role Of The Liver And Pancreas

It secretes insulin and produces enzymes needed for digestion, which are secreted into the gut or small intestine (American Heritage: Student Science Dictionary 253). There is one hormone in the pancreas (How Sweet is it! Measuring Glucose in Your Food). A pancreas is located directly behind the abdomen. The average pancreas is about 6-10 inches (Medical News Today). A hormone is a substance produced in one part of the body, especially in an endocrine gland, that has an effect on another part of the body, which it is usually carried in the blood stream. Hormones regularly many biological processes, including growth and metabolism (American Heritage: Student Science Dictionary 169). Insulin is a hormone produced in the pancreas that acts to regulate the amount of sugar in the blood by causing cells especially liver and muscle cells, to absorb glucose from the blood stream (American Heritage: Student Science Dictionary 182). It helps breaking down carbohydrates in the body. It is made of many beta cells that after responses when blood sugar rises (Medical News Today). Insulin helps the liver absorb glucose just in case the body needs energy when stressed or exercising (Ray). This hormone helps the level of glucose in the blood stream (How Sweet is it! Measuring Glucose in Your

"Cancer of the pancreas is a genetic disease that is the fifth most common cause of death in both men and women. Pancreatic cancer affects approximately 28,000 Americans each year, or five out of 100,000 people" (Mayo Clinic, 1998). According to physicians at Johns Hopkins Medical Institute, "pancreatic cancer is the challenge of the twenty-first century." So, where exactly is the pancreas located in our bodies, and what does it do? The pancreas is a gland found behind the stomach that is shaped somewhat like a fish. The pancreas is about six inches long and less than two inches wide, and it extends across the abdomen. The pancreas consists of two separate glands inside the same organ, the exocrine gland and the

When the blood glucose levels rise above the optimum, the pancreas detects this, and sends a metabolic signal for the pancreas to produce insulin in the beta cells. The beta cells are a part of a cluster of cells called the Islets of Langerhan. The hormone insulin is made here because the pancreas is a part of the endocrine system. (4) Insulin helps our cells convert glucose into energy, and it helps our bodies store extra glucose for use later. Insulin does this by turning the extra food into larger packages of glucose called glycogen. Glycogen is stored in the liver and muscles. When the body consumes food the pancreas will produce more insulin than normal as more is needed, and less insulin when it is not needed as much. (7)

The pancreas, located behind the stomach, is a long, thin organ about the length of the hand. It

The pancreas is responsible for secreting digestive enzymes into the duodenum. These enzymes then break down protein, fats and carbohydrates. The pancreas is also responsible for making insulin and secreting it directly into the bloodstream. The livers main function within the digestive system is to process the nutrients which are absorbed from the small intestine. Bile is secreted

The common bile duct originates in the liver and the gallbladder and produces another important digestive juice called bile. The pancreatic juices and bile that are released into the duodenum, help the body to digest fats, carbohydrates, and proteins. Endocrine Function: The endocrine component of the pancreas consists of islet cells that create and release important hormones directly into the bloodstream. Two of the main pancreatic hormones are insulin, which acts to lower blood sugar, and glucagon, which acts to raise blood sugar. Maintaining proper blood sugar levels is crucial to the functioning of key organs including the brain, liver, and kidneys.

The pancreas is located between the stomach and small intestine, and secretes insulin and glucagon to balance blood sugar levels in the body. When the pancreas does not work properly, a person may be diagnosed with diabetes mellitus, which is more commonly known simply as Diabetes (Morris and Maisto, 2002). People with diabetes suffer from extreme thirst, fatigue, lack of or increased appetite, and a myriad of other symptoms if their condition is not controlled properly with diet, exercise, and medications (if needed) (Steadman’s Concise Medical Dictionary, 2001).

Inside the pancreas there are exocrine and endocrine glands. The exocrine glands make pancreatic "juice" that

Pancreatic Cancer Axia College (2009) Pancreatic cancer is an abnormal, uncontrolled growth of the cells in the pancreas, which is a digestive gland located behind the stomach. The pancreas is both an endocrine and exocrine gland. Cancer of the exocrine pancreas is more common than cancerof the endocrine pancreas. Pancreaticcancer is the fourth leading cause of cancer related deaths among men and women. Pancreatic cancer remains both a challenge to diagnose and even a greater challenge to treat effectively. What is the pancreas? The pancreas is a spongy, tube-shaped organ about six inches long. The pancreas is located in the back of the abdomen, behind the stomach. The head of the pancreas is on the right side of the abdomen. The

Pancreas - The pancreas is a small organ located near the lower part of the stomach and the beginning of the small intestine. This organ has two main functions. It functions as an exocrine organ by

The pancreas is an organ in the abdomen that sits before the spine over the level of the belly button. It performs two important things. First off, it makes insulin, a hormone that regulates glucose levels; secondly, it makes compounds which help separate proteins. The chemicals help digestion by breaking proteins into littler parts so they can be all the more effortlessly digested by the body and utilized for vitality. Proteins leave the pancreas through an arrangement of tubes called "ducts" that associate the pancreas to the digestion systems. The pancreas sits somewhere down in the stomach and is in close vicinity to numerous important structures, for example, the small intestine (the duodenum) and the bile pipes, and in addition critical veins and nerves.

The hormone which is made by the pancreas is said to be insulin that permits the body to utilize sugar from carbohydrates and its maintain energy for future use. Insulin mainly helps to maintain the sugar level in blood from getting high to low. The cells in the body require energy which can get from sugar and it cannot go directly into the cells. After eating the food, blood sugar level increases that time the cells in the pancreas will give signal to release insulin in the blood stream. Insulin after attaches to and the cell in signal will absorb sugar in the bloodstream. Insulin is termed as key which open the cell to allow the sugar into the cell and it can be used for energy.

The pancreas is a vital part of the digestive system and a critical controller of blood sugar levels.

An organ called the pancreas makes insulin. The role of insulin is to move glucose from the bloodstream into muscle, fat, and liver cells, where it can be used as fuel.

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is
