Verified step by step guidance

1. Identify the function of the pancreas in the endocrine system. The pancreas is primarily responsible for regulating blood sugar levels.
2. Understand the role of insulin. Insulin is a hormone that helps lower blood glucose levels by facilitating the uptake of glucose into cells.
3. Recognize that thyroxine is produced by the thyroid gland, not the pancreas. Thyroxine is involved in regulating metabolism.
4. Note that cortisol is produced by the adrenal glands. Cortisol is involved in stress response and metabolism regulation.
5. Adrenaline, also known as epinephrine, is produced by the adrenal glands and is involved in the 'fight or flight' response.
