Document Summary
How your body knows where to send your signals and what signals to send to keep you alive. Claude ber(cid:374)ard is (cid:272)o(cid:374)sidered the father of (cid:373)oder(cid:374) ph(cid:455)siolog(cid:455). People did(cid:374)"t re(cid:272)og(cid:374)ize that our body stays relatively constant no matter the external factors (environment). These are negative feedback loops: one exception: childbearing (reproductive system) The h(cid:455)pothala(cid:373)us is the (cid:862)ther(cid:373)ostat(cid:863) of the (cid:271)od(cid:455): temp falls, thermostat detects a problem (sensory), your body warms (response), you warm up, go back up, thermostat turns off. An example is standing up too fast. Homeostasis has four key things: sensor constant monitoring. These mostly come from the nervous and endocrine system. Integrating centre to coordinate: response system to changes, this is a negative feedback loop. Homeostasis maintained in large part by the endocrine system. We start here because everything comes back to this, if someone is wrong with your endocrine system it will impact the rest of your body.
