Basophil	White blood cell that stains readily with basic
anitgen	Substances, usually a protein fragment, that causes an immune response
Oxytocin	Hormone secreted by the posterior pituitary gland before and after delivering a baby; thought to initiate and maintain labor, as well as cause the release of breast milk into ducts of the mammary glands.
Positive feedback	feedback control system that is stimulatory; tends to amplify or reinforce a change in the internal environment.
