Document Summary
The reacive scope of a homeostaically controlled funcion is a property of the control and communicaion network (ccn) Consider the stress of exercising on a very hot humid day: need to defend the core body temperature, which leads to dilaion of vessels in the skin to dissipate heat, leading to a decrease in mean arterial pressure. Answer: so, maintain temperature compromises the ability to regulate blood pressure. We can esimate when we are solidly within the safe reacive range. This may be useful in p4 medicine where we use predicive outcomes. This graph is based on a mechanical heaing and cooling system-remember that homeostaic systems are dynamic and always moving, i. e. , not a simple patern of variaion like the graph pictures. The body is not a machine, it is a living system with biological complexity, chaos . There are non-random, chaos-like paterns in human temperature variaion-not pulses". Thermoregulaion is part of a complex biological network.
