6. Gland: A gland is a group of cells that produces and secretes (releases) hormones, to use elsewhere in the body.

7. The major glands of the Endocrine System
Hypothalamus
Pituitary Gland
Thymus
Thyroid
Parathyroid Glands
Adrenal Glands
Pineal Gland
Reproductive Glands
Pancreas

8. The Hypothalamus Located in lower-central part of brain.
Main link between the Endocrine and the Nervous Systems.
Nerve cells here control the pituitary gland by producing chemicals that either stimulate or suppress hormone secretion in the pituitary.

10. All Other Glands Hypothalamus
Hypothalamus: At the base of the brain and regulates the other endocrine glands.

12. 8 endocrine glands release 8 different hormones and control different processes in your body.

13. Pituitary Gland: Communicates to hypothalamus (neurons). Size of pea.
Controls blood pressure, growth, metabolism

14. Energy Generation and Use
Metabolism: Chemical reactions that happen in living organisms to maintain life.

It’s complicated

16. The Pituitary Gland The size of a pea!
Located at the base of the brain.
The most important gland.
Divided into two parts:
1. The Anterior Lobe
2. The Posterior Lobe

18. The Anterior Lobe
Produces many different types of hormones, including growth hormones.
Also releases endorphins.
Endorphins are chemicals that reduce the feeling of pain.

19. The Posterior Lobe
Releases a hormone that helps control the balance of water in the body.

20. T Cell Thymus: Responsible for development of immune system.
T cells or T lymphocytes are a type of lymphocyte (white blood cell) that play a central role in immunity.

21. Thyroid: Controls how quickly the body uses energy, makes proteins, and controls how sensitive the body should be to other hormones.

22. Thyroid: Controls how quickly the body uses energy, makes proteins, and controls how sensitive the body should be to other hormones.
Parathyroids release hormones that controls calcium levels in body for nerves and muscles.

23. The Thyroid In the front part of the lower neck.
Controls the rate at which cells burn fuels from food to produce energy.

24. The Parathyroid Glands
Regulate the amount of calcium in the blood.

25. Adrenals: Produces adrenaline, part of emergency action plan, puts you on high alert.

26. The Adrenal Glands: Two located on the top of each kidney.
Triangular shaped.
Outer part = adrenal cortex.
Inner part = adrenal medulla.

27. The Adrenal Glands

29. Adrenal Cortex Regulates: Salt and water balance in the body.
How you respond to stress.
Metabolism.
Immune system.
Sexual development.

30. Adrenal Medulla Creates adrenaline.
Increases blood pressure and heart rate.

31. The Pancreas Also a part of the digestive system.
Produces insulin and glucagon.
Helps maintain the level of sugar in your blood.

32. Pancreas: Produces insulin, which keeps sugar (glucose) in blood under control.
Helps body absorb sugar and use it for energy.
Turns excess sugar into a storage molecule called glycogen.
