In the arteries, constriction of blood vessels causes an increase in blood pressure. [24] In the kidneys, release of renin and retention of sodium in the bloodstream. [25] In the liver, an increase in production of glucose, either by glycogenolysis after a meal or by gluconeogenesis when food has not recently been consumed. [25]
