MESSENGERS
ENDO = INSIDE, CRINE = SECRETE
Endocrine glands release hormones straight into the bloodstream — no pipes to the outside world. Each hormone is a chemical word; target cells with matching receptors read the message and change behaviour. Speed is minutes to days, not milliseconds like a nerve zap, but the effects can last and spread everywhere the blood goes.

Nervous = fast, wired routes. Endocrine = broadcast chemicals for whole-body coordination.
