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). This results in the hormone, angiotensin II being released, causing vasoconstriction, therefore increasing blood pressure and sodium uptake, along with increasing aldosterone hormone release, causing a rise in the uptake of water in the kidneys.

If we drink too much and become hypohydrated (overhydrated), our kidneys increase filtration rates to deal with the increased blood pressure, subsequently, aldosterone levels decrease, resulting in more water being extracted from the blood and deposited through urination. The Ku-band scatterometer called CSCAT onboard the Chinese-French Oceanography Satellite (CFOSAT) is the first spaceborne rotating fan-beam scatterometer (RFSCAT).
