ENDOCRINE SYSTEMDry Lab Questions • Function: maintain homeostasis • Thymus gland(site of maturation of white blood cells) • Thyroid gland (secretes thyroid hormone and calcitonin) • Parathyroid gland (secretes parathyroid hormone) • Adrenal gland (secretes aldosterone) • Pituitary gland (secretes FSH, etc. The neurohypophysis stores and releases hormones produced in the hypothalamus) • Ovary (also an endocrine gland; secretes estrogen) • Testes (secretes testosterone) • Pancreas (secretes insulin; lack= diabetes mellitus)
