Vascular shunting is regulated by the sympathetic nervous system, which controls blood flow through vasodilation (opening of the arterioles, increasing flow of blood into the capillaries) and vasoconstriction (constricting of the arterioles, decreasing the flow of blood into the capillaries). 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.
