Which system is responsible for the release of hormones that control activities in the body?

The endocrine system is responsible for the release of hormones that regulate a wide array of bodily activities, including growth, metabolism, and reproduction. Hormones are chemical messengers produced by glands in the endocrine system, such as the pituitary, thyroid, and adrenal glands. Once released into the bloodstream, these hormones travel to various tissues and organs, where they exert their effects, influencing processes such as mood, energy levels, and homeostasis.

This system operates more slowly than the nervous system, which uses electrical signals to transmit information rapidly, but the effects of hormones can last for a longer period. The interaction between the endocrine system and other body systems is crucial in maintaining overall health and well-being.
