  1. Warm-up (4/25) • What glands act as antagonists to the thyroid gland? • Tetany indicates the malfunction of which gland? • Where is insulin produced? • What is insulin’s antagonistic hormone?

  2. ovaries • HORMONE ESTROGEN: • Produced by Graafian follicles or the placenta • Stimulates the development of secondary female characteristics • Matures female reproductive organs • Helps prepare the uterus to receive a fertilized egg • Helps maintain pregnancy • Prepares the breasts to produce milk

  3. ovaries • HORMONE PROGESTERONE • Produced by the corpus luteum • Acts with estrogen to bring about the menstrual cycle • Helps in the implantation of an embryo in the uterus

  4. TESTES • Interstitial cells of testes are hormone-producing • Produce several androgens • Testosterone is the most important androgen • Responsible for adult male secondary sex characteristics • Promotes growth and maturation of male reproductive system • Required for sperm cell production

  5. Other Hormone-Producing Tissues and Organs • Parts of the small intestine • Parts of the stomach • Kidneys • Heart • Many other areas have scattered endocrine cells

  6. Endocrine Function of the Placenta • Produces hormones that maintain the pregnancy • Some hormones play a part in the delivery of the baby • Produces HCG in addition to estrogen, progesterone, and other hormones

  7. Developmental Aspects of the Endocrine System • Most endocrine organs operate smoothly until old age • Menopause is brought about by lack of efficiency of the ovaries • Problems associated with reduced estrogen are common • Growth hormone production declines with age • Many endocrine glands decrease output with age
