The mechanism that regulates hormonal balance in the body is known as the endocrine system. It comprises various glands that produce hormones, which serve as chemical messengers to communicate between different parts of the body. Key components of this system include the hypothalamus, pituitary gland, thyroid, adrenals, and pancreas. Feedback mechanisms, such as negative feedback, maintain homeostasis by adjusting hormone levels in response to physiological changes. This coordination is essential for numerous bodily functions, including metabolism, growth, and reproductive health.
