Abstract
Hormones are important biologically active substances in the human body. They are produced by the endocrine glands and regulate various processes in the body. Hormones maintain body balance and regulate vital functions. Hormones perform many functions in the body. They spread through the blood, affecting various organs and tissues. First, hormones control growth and development. For example, growth hormone promotes bone and muscle development in children.
Secondly, hormones regulate the metabolism. For example, thyroid hormones control energy metabolism in the body. Third, hormones control the stress response reaction. For example, the hormone adrenaline prepares the body for rapid action in dangerous situations.
