Explanation:

The primary role of the endocrine system is to control body processes via the production, secretion, and regulation of hormones. These hormones serve as chemical 'messengers' that drive cellular and organ activity, playing crucial roles in growth, metabolism, and sexual development. The endocrine system comprises of endocrine glands, which secrete hormones directly into surrounding fluids to be transported around the body via interstitial fluid and blood vessels.

Key components include the pituitary, thyroid, parathyroid, adrenal, and pineal glands as well as other organs like the hypothalamus, thymus, heart, kidneys, stomach, and small intestine, which contain cells with endocrine functions. Additionally, tissues like adipose tissue and even bones can produce hormones. By regulating the release of these hormones, the endocrine system aids in maintaining the body's homeostasis and adjusts physiological activity in response to changes in internal or external environmental conditions.
