Question

One of the major functions of the human pancreas is to release hormones in order to quickly and precisely control levels of glucose in the blood. The diagram shows the structure of a pancreatic islet. Pancreatic islets are made up of tightly packed beta cells, which are responsible for the production of the hormone insulin, as well as blood vessels that run throughout the structure. Insulin is one of the primary hormones involved in glucose regulation. Based on this information, which statement best describes how the structure of a pancreatic islet helps the body regulate blood glucose levels?
A. The structure of a pancreatic islet allows the islet to act as a vesicle where excess hormones can be stored.

 B. The structure of a pancreatic islet enables hormones to be released directly into the bloodstream.
 C. The structure of a pancreatic islet enables hormones to be removed from the bloodstream and broken down.
 D. The structure of a pancreatic islet prevents hormones from combining in the bloodstream.

Answer 1

In general, the pancreas is one of those organs in our body the regulates hormones, specifically insulin and glucagon. Insulin is very essential in the control of blood sugar for these serves as the vehicle in order to distribute these sugars to all the cells in the body. Based on the description above, the structure of the pancreatic islets helps in the regulation of blood sugar enables the hormones to be released directly into the bloodstream. The answer is B.
