How do your hormones work? – Emma Bryce

Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, skinmuscles and other tissues. These signals tell your body what to do and when to do it. Hormones are essential for life and your health.
Scientists have identified over 50 hormones in the human body so far.
Hormones and most of the tissues (mainly glands) that create and release them make up your endocrine system. Hormones control many different bodily processes, including:
Homeostasis (constant internal balance), such as blood pressure and blood sugar regulation, fluid (water) and electrolyte balance and body temperature.
Growth and development.
Sexual function.
Sleep-wake cycle.
With hormones, a little bit goes a long way. Because of this, minor changes in levels can cause significant changes to your body and lead to certain conditions that require medical treatment.
