1. Endocrine System Histology and Models

2. ENDOCRINE SYSTEM Dry Lab Questions
Function of the endocrine system: to 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)
