  1. 29.1/6 Endocrine System and Hormones 2.1 Atoms, Ions, and Molecules Set up Cornell Notes on pg. 37 • Topic: 29.1/6 Endocrine System and Hormones • Essential Question(s): 1. Create a double-bubble map comparing and contrasting the nervous system and the endocrine system. TEST TOMORROW KEY CONCEPT The endocrine system provides one of the means by which organ systems communicate and it produces hormones that affect growth, development, and homeostasis.

  2. KEY CONCEPT The endocrine system provides one of the means by which organ systems communicate and it produces hormones that affect growth, development, and homeostasis.

  3. Connect • If you hear a loud BANG, your brain tells your body that you could be in danger • You may need to run or defend yourself • Your brain alerts your endocrine system to send out chemicals that will speed up your heart rate, increase blood flow to your muscles, and get you ready for action!

  4. The endocrine system makes chemical signals that control growth, development, and digestion. • It is a collection of physically disconnected organs • responds to environment • May control: • Cell division • Cell death • Sexual development • Body temperature • Alertness • Salt levels…

  5. The chemical signals made by the endocrine system are called hormones, which are chemical signals or messengers that influence cell’s activities.

  6. target cell hormone receptor bloodstream not a target cell • Glands, the organs of the ES, produce hormones and are found in many different areas of the body • secrete hormones into the blood stream • As a hormone moves through the body, it comes into contact with many different cells • But it can only interact with a cell that has specific membrane receptors

  7. Only cells with certain receptors can receive the signals • Works like a satellite system • Sends signals in all directions, but you need special receivers to get the signals

  8. receptor target cell hormone bloodstream not a target cell • Works more slowly than the nervous system.

  9. Hypothalamus: makes hormones that stimulate other glands to release hormones Pituitary: controls growth and water in blood Thyroid:metabolism, energy levels, digestion Thymus: helps white blood cells fight off infection Adrenal Glands: breathe faster, increase blood pressure- heart increases strength Pancreas: Controls blood sugar by adding or removing sugar from the blood Ovaries and Testes: Cause sexual maturation, influence sexual characteristics • There are many glands located throughout the body.

  10. The Endocrine System (3m)

  11. 1) How does releasing hormones help glands to communicate with one another? • The glands are not connected. Releasing hormones stimulate other glands to produce and release their hormones.

  12. Hormonal imbalances can cause severe illness. • Abnormal hormone levels affect homeostasis. • Hormonal imbalances might be treated with surgery or medicine.

  13. Robert Wadlow- (1918-1940) • 8 ft 11.1 in and 485 lbs • Pituitary gland disorder- gave him too much of the growth hormone • Used leg braces to walk, had little feeling in his legs and feet • Died at the age of 22 from an infected ankle blister Tallest man EVER recorded!

  14. Jon Brower Minnoch (1941-1983) • Heaviest man ever recorded • Peak weight 1,400 lbs • Suffered from generalized edema – his body retained massive amounts of fluid. Over 900 lbs was due to the fluid. • Was hospitalized. Put on a strict diet and dropped to 475 lbs • Returned a yr later weighing 952 lbs • They discontinued treatment because his edema was incurable

  15. Body Story: Teen Dreams (45 mins) • NEED EXTRA CREDIT??? • Watch “Body Story: Teen Dreams” • Write ½ page summary and turn in by Friday • Focus on the glands of the Endocrine System discussed • https://www.youtube.com/watch?v=DGVPQF03tfI

  16. EQ: Top P. 36 • Create a double-bubble map comparing and contrasting the nervous system and the endocrine system. • Must have at least two pictures per system

  17. Homework/Classwork: Bottom p. 36 1)Write name of organ 2) Draw an outline of a person 3) Draw the organ/ Location? 4) Explain what it does (898) 5) What hormones does it make? (899) *Be prepared to share tomorrow Endocrine System Organ • Hypothalamus • Pituitary • Thyroid • Thymus • Adrenal Glands • Pancreas • Gonads: Ovaries • Gonads: Testes Pg. 898-899

  18. Slim Goodbody: The Inside Story: Little Giants: Glands2m-6m26s) • Yes…I’m serious

  19. Quick Send signals Slower Includes CNS and PNS disconnected Respond to stimuli Connected network Nervous system Endocrine system Chemical Signals Controls thoughts and movement Maintain homeostasis Controls growth and development Electrical Signals
