Gauer-Henry reflex




The headward shift of fluids seen in spaceflight is thought to produce a transient increase in central blood volume; the transient increase is detected by stretch receptors in the heart and interpreted as an increase in total blood volume. A compensatory loss of water and sodium is then thought to be effected by a series of neural, humoral and direct hydraulic mechanisms.
