Answer:
D. Pancreas
Step-by-step explanation:
The pancreas is a gland that has several functions, one of the main functions is as an exocrine gland by secreting digestive enzymes, such as amylase and lipase into the GI tract when the food is passing through the duodenum, these enzymes contribute to break down fats and proteins into small portions so these can be absorbed easily by the large intestine. The second most important function of the pancreas is as an endocrine gland during insulin secretion through the islets of Langerhans. Insulin is a hormone that is released in the bloodstream during digestion and it is responsible for regulating blood sugar levels by distributing it in the different organs.
