Transcript THE ENDOCRINE SYSTEM

THE
ENDOCRINE
SYSTEM
ENDOCRINE SYSTEM …
• Contains glands that have many different jobs in your body
– Regulates metabolism, growth and development, sexual function,
reproduction, and sleep/mood.
• Hormones and glands are the foundations of the endocrine
system.
• Triggers your secondary sex characteristics to start PUBERTY
• Hormones: Transfer information and instructions from one cell to
another.
• Glands: Group of cells that produce and secrete or gives off
chemicals.
– Most important gland is the Pituitary Gland
PITUITARY GLAND
• Tiny gland located in your brain, powerful
• “Master Gland”
• Controls the activities of all endocrine glands.
• Works with Hypothalmus to make your body work.
• Controls the hormones ADH, Oxytonin, and ACTH
Hormone
Prolactin
Adrenocorticotropic Hormone
(ACTH)
Function
Develops breast tissue
Stimulates production of milk for breast
feeding.
Stimulate Adrenal Cortex
-Helps manage stress.
Follicle Stimulating Hormone
(FSH)
Stimulate production of sex hormones
Female: Estrogen – Ovulation
Males: Testosterone - Sperm
Leutenzing Hormone
(LH)
Stimulates ovulation and produces
progesterone in females.
Vasopressin
-Triggers Antidiuretic Hormone
-Acts on kidney, concentrates urine, and
preserves water in the body.
Oxytocin
-Released during childbirth
-Starts contractions of uterus.
Somatotropin
Growth and Development
Growth Hormone (GH)
GLANDS CONT:
• Hypothalmus
– Regulates all hormones in the body
– Works directly with the Pituitary Gland.
• Pineal Gland
– Location: Center of the Brain
– Looks like a Pine Cone
– A.K.A Third Eye
– Produces Melatonin; which regulates our wake/sleep cycle.
• Thyroid Glands
– Control calcium and phosphorus levels in the body.
– Thyroid: controls metabolism and growth. (HYPO/HYPER)
– Located in your neck; looks like a bowtie
• Pancreas
MORE GLANDS!
– Location: Behind the Stomach
– Involved with Production of Insulin
• Hypothalmus
– Regulates all hormones in the body.
– Works directly with the Pituitary Gland
• Adrenal Gland
– Produces reaction to stress or emergency situations.
– Fight or flight gland
– What word does Adrenal gland remind you of?
• Thymus
– Location: Sternum
– Disappears after puberty, and eventually replaced by fat.
– Helps with T-Cell development, and fight infection.
GONADS
• Depending on whether you are MALE or FEMALE these hormones go
to work on different parts of the body.
• OVARIES IN FEMALES
• TESTES IN MALES
