Introduction The Digestive system breaks down the ingested food into absorbable forms of nutrients and absorbs nutrients‚ ions and water from the external environment of the body. It is designed to maximize digestion and absorption. The functional structures of the digestive system are the passage‚ the glands like salivary glands‚ gastric glands‚ pancreatic‚ intestinal glands and liver. Also‚ the four layers of the digestive system are mucosa‚ submucosa‚ muscularis and serosa. The digestive system

Types of Pancreas Surgery Whether you have cysts‚ lesions‚ or tumors related to your pancreas‚ the type of pancreatic surgery that you will need will depend on where they are located. After a thorough analyst of your individual situation‚ your Glendora General Surgeon will determine the method of operation‚ open or laparoscopic‚ and the type of surgery‚ Distal Pancreatectomy‚ Total Pancreatectomy‚ or Whipple‚ which will best fit your needs.

divides cancers into groups based on whether or not they can be removed by surgery. * Resectable - The surgeon can remove the entire tumor. These tumors may be in the pancreas or beyond it‚ but they have not spread to the critical arteries or veins in the area. There is no evidence of any spread to areas outside of the pancreas. * Locally advanced (unresectable) - The cancer cannot be removed (resected) by surgery because it has spread to critical arteries‚ veins‚ or surrounding organs.

During the 45-60 minute mark the glucose should decrease to normal values. This happens only if the individual’s pancreas is functioning correctly. 6. In your own words‚ explain what insulin resistance is. Insulin resistance is the inability to produce insulin by the pancreas. The

What is pancreatic cancer? Pancreatic cancer is an aggressive form of cancer that develops in the tissues of the pancreas. Located in the abdomen behind the lower part of the stomach‚ the pancreas aids in digestion. It contains both exocrine glands (which produce enzymes that help the body digest food) and endocrine glands (which produce hormones‚ including insulin‚ that help control blood sugar levels in the body). Pancreatic cancer is hard to diagnose and once it is found it has usual spread to

The inflammation of the pancreas results from an obstruction of the bile and pancreatic duct‚ which then impedes the outflow of pancreatic digestive enzymes (Huether & McCance‚ 2012). Thereafter‚ the occluded ducts cause the accumulation of pancreatic secretions along with the activation of specific enzymes within the pancreas‚ which further activate other enzymes (Huether & McCance‚ 2012). For example‚ activated trypsin then

In 1869 a young medical student in Berlin named Paul Langerhans was interested in learning about the structure of the pancreas. He discovered there were clumps of tissue clustered in the pancreas. Langerhans never learned the function of this tissue. These cells became known as the Islets of Langerhans. He never realized he would be associated with who discovered diabetes. Langerhans’ son‚ Archibald‚ and
