• System of check and balance
• Hormone

  A chemical messenger which targets a specific group of cells.
• Glands is an organ that makes one or more substances such as hormones.
• Endocrine glands releases substances directly into the bloodstream to regulate body function
• Exocrine glands release the substances into a duct to perform physiological functions.
• Liver: Bile released into the gallbladder then through a duct into small intestine.
• Pancreas release pancreatic juice into the small intestine via a duct
• Gland: Hypothalamus

  Hormones: Oxytocin stimulates the muscles of the uterus to contract and boost production of prostaglandins.

  ADH: Anti-diuretic hormone that increases water uptake in kidney

  
• Function of hypothalamus: regulates body activity, temperature, metabolism.
• Gland: Pituitary

• Thyroid is located at base of neck.
• Gland: Parathyroid
