The Endocrine System
The human body has 11 major endocrine glands, including the thyroid, pancreas, stomach, adrenal, pituitary and thymus. The endocrine glands and tissues secrete hormones, the substances that regulate the body’s reproduction, growth and development, its response to the environment, and the provision of the energy and nutrients needed for cell function. Endocrinologists conduct research and provide treatment for a wide range of functions and disorders of the human body, including infertility, metabolism, glandular cancers, birth control, dwarfism, genetic dysfunction, diabetes, heart disease, and hormonal imbalances. Endocrinologists also develop new drugs and treatments through biogenetic and synthetic techniques.
