But our systems are much more complex than just one variable …
Can restoring one variable to its normal set point compromise the ability
to regulate another?
Consider the stress of exercising on a very hot and humid day …
Need to defend body core temperature … leads to dilation of vessels in
the skin to dissipate heat. BUT, this further reduces total peripheral
resistance (remember the CV lectures!) … leading to a decrease in
mean arterial pressure ! So maintaining temperature compromises the
ability to regulate blood pressure.
yes, homeostatic load is distributed across the CCN (multiple/all homeostatic systems) so for these people who had a reduced reactive scope when
these happened 11...
