Answer:
Pancreas. 
Explanation:
Pancreas is an organ that acts as both exocrine as well as endocrine gland. As exocrine gland, it secretes digestive enzymes into the small intestine that help in digestion of complex food molecules. 
As an endocrine gland, it secretes glucagon (from alpha cells) and insulin (from beta cells) hormones, directly into the bloodstream. Both of these hormones are responsible for the regulation of blood sugar level in the body. 
Thus, the correct answer is 'pancreas.'

Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs.
