Step-by-step explanation:
Endocrine glands are specialized glands in the human body that secrete hormones directly into the bloodstream. These hormones, in turn, travel through the bloodstream to target organs and tissues, where they exert their effects. The endocrine system plays a crucial role in regulating various physiological processes, including growth and development, metabolism, energy balance, mood, and reproduction.
