Which organ system protects against environmental hazards, helps regulate body temperature, and provides sensory information? 1 above), which presents the stages human motivation moves through. Oxytocin production and secretion is controlled by a positive feedback mechanism where release of the hormone causes an action that stimulates more of its own release. [1] 'Homeo,' Latinized from the Greek word 'homio,' means 'similar to,' and when combined with the Greek word 'stasis,' meaning 'standing still' gives us the term that is a cornerstone of physiology. The hormone then causes an action in the body, such as the letdown of milk or the start of labor contractions, which signals more production of oxytocin. The researchers would need to, in effect, make a video of the microbiome and the human body. Why is positive feedback useful to the human body?
