Transcript of Unit 6 - Endocrine System

THE ENDOCRINE SYSTEM
HINSDALE CENTRAL HEALTH EDUCATION
The endocrine system sends and receives hormones using endocrine glands.
The endocrine system includes various organs that work together to regulate body functions.
How the Endocrine System Works
Chemical substances that help regulate many of your body’s functions
Hormones
Ductless or tubeless organs or groups of cells that secrete hormones directly into the bloodstream
Endocrine glands
Pancreas
Adrenal Glands
Thymus
Pituitary Gland
Pineal Gland
Hypothalamus
Ovaries
Testes
Parathyroid Glands
Thyroid Gland
Major Glands of the Endocrine System
How the Endocrine System Works
The anterior, or front, lobe of the pituitary gland produces these hormones:
Stimulates production of all other sex hormones
Stimulates production of hormones in the adrenal glands
Stimulates the thyroid gland to produce hormones
Follicle-Stimulating
Hormone and
Luteinizing Hormone
Adrenocorticotropic
Hormone
Thyroid-Stimulating
Hormone
Stimulates normal body growth and development
Somatotropic
(Growth Hormone)
Anterior Lobe
The intermediate, or middle, lobe of the pituitary secretes melanocyte-stimulating hormone, which controls the
darkening of the pigments in the skin.
Intermediate Lobe
The posterior, or rear, lobe of the pituitary secretes antidiuretic hormone that regulates the
balance of water
in the body, and produces
oxytocin
, which stimulates the smooth muscles in the uterus during pregnancy, causing contractions during the birth of a baby.
Your endocrine health is directly related to your overall health.
To keep your endocrine system working at its peak, you need to follow sound health practices.
