Generation of GCaMP6s-Expressing Zebrafish to Monitor Spatiotemporal Dynamics of Calcium Signaling Elicited by Heat Stress. A reduction in hydration results in a decrease in blood volume and pressure, which results in cells becoming more concentrated and the kidneys not functioning effectively (decreased filtration). The decrease in blood plasma results in a decrease in venous return, the volume of blood returning to the heart, and therefore a decrease in stroke volume, the volume of blood ejected from the left ventricle per beat. When we sweat, a portion of the lost fluid volume comes from the plasma volume. Cardiovascular drift, the progressive increase in heart rate and decrease in stroke volume that begins after approximately 10 min of prolonged moderate-intensity exercise, is associated with decreased maximal oxygen uptake, particularly during heat stress. et al. doi: 10.14814/phy2.14841.
