The Different Body Parts Insulin Stimulates

2. Sodium Reabsorption

Insulin is needed to balance the excretion of sodium and the volume of fluid in urine. Sodium transport is an important part of regulating blood pressure and sodium reabsorption. Although there are several regulators involved in the process of sodium transport, insulin is one of the most important as it is a potent enhancer of sodium reabsorption. Although insulin has vasodilatory properties, meaning that it widens blood vessels, these effects may be altered when insulin resistance or high blood sugar is present, which contributes to high blood pressure.
