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.
Both hormones lower blood pressure by relaxing arterioles; inhibiting the secretion of renin and aldosterone; inhibiting the reabsorption of sodium ions by the kidneys. The latter two effects reduce the reabsorption of water by the kidneys. So the volume of urine increases as does the amount of sodium excreted in it. The net effect of these actions is to reduce blood pressure by reducing the volume of blood in the circulatory system.
