Autonomic Control Of The Circulation
Autonomic control of the circulation primarily operates through the sympathetic
system, though to a slight extent through parasympathetic signals to the heart.
These have been lumped together, and there are basically three separate feedback
mechanisms in this computational block. These are: (1) feedback from the
baroreceptor control system; (2) feedback from the peripheral chemoreceptors in
the carotid and aortic bodies,; and (3) feedback control of the circulatory system
caused by central nervous system ischemia, that is, ischemia of the vasomotor center
of the brainstem. Several other inputs that affect the autonomic nervous system are
also included. These are: activation of the autonomic nervous system during exercise;
baroreceptor feedback effects from pulmonary artery pressure (PPA), left atrial
pressure (PLA), and an effect of low blood PO2 (PO2ART).
Note: Not shown in the diagram is also a variable (STA) that is normally zero.
When it is set to any level above zero, the value of the general autonomic multiplier (AU)
becomes fixed to the value of STA.
WHERE DO I PUT THIS NOTE?????
