âIt wasnât a Tennessee orange,â Little said, âand it was not a pumpkin orange kind of thing either.â Texas used that color until the early 1960s, when Darrell Royal was in the midst of revamping the football program.
1 If the body is becoming fluid-deficient, this will be sensed by osmoreceptors, which results in increased secretion of ADH, causing fluid to be retained by the kidneys and urine output to be reduced.  The hormones ADH (Anti-diuretic Hormone, also known as vasopressin) and aldosterone play a major role in this.
Natriuretic hormones act by inhibiting aldosterone release and therefore inhibiting Na+ recovery in the collecting ducts. If Na+ remains in the forming urine, its osmotic force will cause a concurrent loss of water. Natriuretic hormones also inhibit ADH release, which of course will result in less water recovery.
