What is the main function of the pancreas?

The pancreas plays a crucial role in both the endocrine and exocrine systems. Its main functions include the production of insulin, which is vital for regulating blood sugar levels, and the secretion of digestive enzymes that aid in the digestion of nutrients in the small intestine. The insulin produced by the pancreas helps cells absorb glucose from the bloodstream, making it essential for maintaining metabolic homeostasis.

Additionally, the pancreas releases enzymes such as amylase, lipase, and proteases that are key to digesting carbohydrates, fats, and proteins, respectively. This dual role—balancing blood sugar levels and facilitating digestion—highlights the importance of the pancreas in overall bodily functions. This makes the option describing its functions accurately embody the essential contributions of the pancreas to both metabolic and digestive processes.
