The largest organ in the endocrine system is the pancreas. This vital organ has both endocrine and exocrine functions but plays a significant role in hormone production. In its endocrine capacity, the pancreas produces important hormones like insulin and glucagon, which help regulate blood sugar levels. Insulin lowers blood glucose, while glucagon raises it, maintaining homeostasis in the body. The pancreas also secretes digestive enzymes into the small intestine to aid in the digestion of food. Its unique dual nature makes it essential for both metabolic and digestive health.
