Answer
The pancreas is the main organ that produces the hormones that control blood glucose in the blood which are glucagon and insulin.
Explanation :
When someone eats, the body digests the food and the sugar will be turned into glucose upon digestion. For the body cells to absorb the glucose, the pancreas will secrete insulin first. Insulin will helps in the intake or absorption of glucose by the cells, thus reducing blood sugar levels. Glucagon will stimulate the liver to release glucose and increase blood glucose levels.
