Answer: Option E. Pancreas
Step-by-step explanation:
When the blood glucose level rises after a meal, the first organ to respond is the Pancreas.
When the blood sugar levels rise, insulin is released by pancreas. Insulin released in the bloodstream helps to absorb the sugar and allows the liver to store sugar. Like this the process lowers the blood sugar level.
When blood sugar levels gets lower the pancreas are allowed to release glucagon, which allows the liver to release the stored sugar. If the blood sugar levels rise, the release of glucagon is stopped.
Hence, the correct option is Pancreas.
