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.
Osmolality of blood increases with dehydration and decreases with overhydration. In normal people, increased osmolality in the blood will stimulate secretion of antidiuretic hormone (ADH). This will result in increased water reabsorption, more concentrated urine, and less concentrated blood plasma. A low serum osmolality will suppress the release of ADH, resulting in decreased water reabsorption and more concentrated plasma.
