Systems physiology of the baroreflex during orthostatic stress: from animals to humans

Frontiers in Physiology, 2014
The baroreflex is a key mechanism involved in the control of arterial pressure (AP) during orthostasis in humans. However, the baroreflex is a closed-loop feedback system, from baroreceptor pressure input to systemic AP, and therefore requires open-loop ...
