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.
