EXOCRINE GLANDS GIVE OFF CHEMICALS THROUGH DUCTS OR TUBES INTO NEARBY ORGANS DO NOT PRODUCE HORMONES PRODUCE TEARS, SWEAT, OIL, AND DIGESTIVE JUICES

ENDOCRINE SYSTEM GLANDS THAT PRODUCE CHEMICAL MESSENGERS CALLED HORMONES RELEASED DIRECTLY INTO THE BLOOD

HORMONES TURN ON OR OFF SPEED UP OR SLOW DOWN DIFFERENT ACTIVITIES OF ORGANS DELIVERED BY CIRCULATORY SYSTEM TISSUE CELLS ARE PROGRAMMED TO ACCEPT CERTAIN HORMONES AND REJECT OTHERS

THE HUMAN BODY HAS EIGHT ENDOCRINE GLANDS THAT RELEASE DIFFERENT HORMONES

HYPOTHALAMUS LOCATED AT BASE OF BRAIN MAJOR LINK BETWEEN THE NERVOUS SYSTEM AND ENDOCRINE SYSTEM CONTROLS THE SEVEN OTHER ENDOCRINE GLANDS

MESSAGES TRAVELING TO AND FROM THE BRAIN PASS THROUGH THE HYPOTHALAMUS

PITUITARY CENTER OF SKULL BEHIND BRIDGE OF NOSE TALKS TO HYPOTHALAMUS THROUGH CHEMICALS AND NERVE IMPULSES BLOOD PRESSURE, GROWTH, METABOLISM, SEXUAL DEVELOPMENT, AND REPRODUCTION

THYMUS BEHIND STERNUM GETS SMALLER AS YOU GROW – BY ADULTHOOD – SIZE OF THUMB DEVELOPMENT OF IMMUNE SYSTEM INFANCY – PRODUCES WHITE BLOOD CELLS

THYROID IN NECK CONTROLS HOW QUICKLY FOOD IS BURNED UP BY THE BODY (METABOLISM)

PARATHYROIDS EMBEDED IN THYROID CONTROLS THE LEVEL OF CALCUIM IN THE BLOOD

ADRENALS ON TOP OF KIDNEYS REACTION TO A DANGEROUS SITUATION –PRODUCES ADRENALINE – THE BODY’S EMERGENCY ACTION TEAM

ADRENAL GLAND

PANCREAS LOCATED BY SMALL INTESTINE INSULIN – KEEPS BLOOD SUGAR LEVELS UNDER CONTROL HELPS THE BODY ABSORB IT AND USE IT FOR ENERGY CHANGES SUGAR INTO GLYCOGEN FOR STORAGE

DIABETES MELLITUS – DROP IN INSULIN PRODUCTION –INSULIN PRODUCED BY SMALL GROUP OF CELLS CALLED ISLETS OF LANGERHAUS –ISLETS ALSO PRODUCE GLUCAGON – OPPOSITE EFFECT OF INSULIN INCREASES BLOOD SUGAR LEVEL

OVARIES FEMALE REPRODUCTIVE GLANDS

TESTES MALE REPRODUCTIVE GLANDS

NEGATIVE FEEDBACK MECHANISM AUTOMATICALLY CONTROLS THE LEVELS OF HORMONES IN THE BODY PRODUCTION OF A HORMONE IS CONTROLLED BY THE AMOUNT OF ANOTHER HORMONE IN THE BLOOD THEREBY KEEPING THE BODY’S INTERNAL ENVIRONMENT STABLE

EXAMPLE: –THE PITUITARY IS SENTITIVE TO THYROXINE (PRODUCED BY THE THYROID) IF TOO LOW – TSH (THYROID STIMULATING HORMONE) IS RELEASED
