  4. 4. • Thyroid gland – below the larynx - regulates metabolism - promotes development of the nervous system • Parathyroid - attached to the thyroid - regulate calcium levels in the body
  5. 5. • Thymus - in the upper chest - hormones produced in the thymus stimulate the production of cells that fight infection • Adrenal glands – on top of each kidney - produce a variety of hormones - help your body adapt to physical and emotional stress (fight or flight)
