Thirst is regulated by the hypothalamus in response to subtle changes in the body's electrolyte levels, and also as a result of changes in the volume of blood circulating.

Famous quotes containing the word thirst:
“The thirst to know and understand,
A large and liberal discontent.”
—Sir William Watson (1858–1935)
“To ask strength not to express itself as strength, not to be a will to dominate, a will to subjugate, a will to become master, a thirst for enemies and obstacles and triumphant celebrations, is just as absurd as to ask weakness to express itself as strength.”
—Friedrich Nietzsche (1844–1900)
“We can conceive a thinking being to have either many or few perceptions. Suppose the mind to be reduced even below the life of an oyster. Suppose it to have only one perception, as of thirst or hunger. Consider it in that situation. Do you conceive any thing but merely that perception? Have you any notion of self or substance? If not, the addition of other perceptions can never give you that notion.”
—David Hume (1711–1776)
