An animal’s endocrine system controls body processes through the production, secretion, and regulation of hormones, which serve as chemical “messengers” functioning in cellular and organ activity and, ultimately, maintaining the body’s homeostasis. The endocrine system plays a role in growth, metabolism, and sexual development. In humans, common endocrine system diseases include thyroid disease and diabetes mellitus. In organisms that undergo metamorphosis, the process is controlled by the endocrine system. The transformation from tadpole to frog, for example, is complex and nuanced to adapt to specific environments and ecological circumstances.
The study of the endocrine system has led to many medical advances. Now scientists have discovered a hormone that mimics the effects of exercise by regulating metabolism and fighting insulin resistance.1 You can read more about this exciting discovery at the Science Daily website.
