Which system in the frog produces chemicals that regulate functions in different parts of its body?

The endocrine system in frogs produces hormones that regulate various bodily functions. These hormones, secreted by glands such as the pituitary, thyroid, and adrenal glands, influence growth, metabolism, reproduction, and stress responses. By releasing these chemical messengers into the bloodstream, the endocrine system helps maintain homeostasis and coordinate physiological activities throughout the frog's body.
