Regulatory Mechanisms in the Endocrine System

In the study of the endocrine system, it is crucial to understand the role of various hormones in regulating physiological processes. One of the hormones that plays a vital role in glucose metabolism is insulin. Insulin is produced by the pancreas and is primarily responsible for facilitating the uptake of glucose by tissues, thereby reducing blood sugar levels. However, another hormone that opposes the action of insulin and is released during periods of stress is glucagon, which increases blood glucose levels. Additionally, stress can trigger the release of catecholamines like epinephrine, which further influence glucose metabolism.

Considering the interplay of these hormones, which of the following statements accurately describes a regulatory mechanism within the human body that involves the endocrine system?
