Question
Remove the digestive organs from the abdominopelvic avily to espose the structures along the posterior wall ocate the elongate pasterior body wall between the duodenum (first part of the smali intestine) and the spleern ed pancreas that stretches across the The head of the pancreas is nestled within the C shaped curvature of the duodenum on the right side The body of the pancreas is the main portion of the organ The tail of the pancreas extends to the left toward the spleen Duo The pancreas is largely composed of glandular cells that produce digestive enzymes, but scattered throughout the organ are regions of endocrine tissue known as pancreatic islets (islets of Langerhans). The ncreatic islets produce two hormones, glucagon and insulin, which regulate blood glucose levels. Glucagon elevates blood glucose levels by promoting the breakdown of glycogen, the synthesis of glucose from fats and proteins, and the release of glucose into the blood. Insulin lowers blood glucose levels by promoting glucose uptake into most cells. Additionally, in skeleta! muscles and in the liver, insulin increases glucose storage by stimulating the production of glycogen If insulin secretion decreased, how would blood glucose levels change? Explain. 348 XERCISE 19 The Endocrine SystenmExplanation / Answer
If insulin secretion is decreased, the blood glucose levels will increase leading to hyperglycemia or high blood sugar levels. Insulin is needed so that the high level of glucose present in the blood can be taken up by the cells in the body, and thus maintain the normal blood sugar levels.
