Hormonal Regulation in Vertebrates

Hormonal regulation in vertebrates involves the release of hormones by glands into the bloodstream to control various bodily functions. Hormones act as chemical messengers, influencing processes like growth, metabolism, reproduction, and response to stress. The major glands include the pituitary, thyroid, and adrenal glands. Hormones communicate with specific target organs, triggering changes and maintaining balance, known as homeostasis. For example, insulin regulates blood sugar levels, while adrenaline prepares the body for 'fight or flight' situations. This intricate system ensures that the body's activities are coordinated and adapt to different circumstances.
