Episode Details

All animals rely on a system of checks and balances to maintain homeostasis. The endocrine system, in conjunction with the nervous system, regulates bodily functions based on the internal and external environments. Both systems act as communication networks: the nervous system uses nerve impulses carried on nerve fibers to rapidly communicate; in contrast, the endocrine system uses hormones carried in the blood for slower, more sustained communication.
