The hormone that influences sodium reabsorption in the kidney is ____.

A) antidiuretic hormone
B) cortisone
C) aldosterone
D) corticotropic hormone
E) adrenaline

Aldosterone is a hormone produced by the adrenal glands that acts on the kidneys to increase the reabsorption of sodium ions and the excretion of potassium ions. This helps to regulate blood volume and blood pressure. Antidiuretic hormone, also known as vasopressin, regulates water balance in the body. Cortisone is a steroid hormone that has anti-inflammatory effects. Corticotropin hormone stimulates the release of glucocorticoids from the adrenal glands. Adrenaline, also known as epinephrine, is a hormone that is released in response to stress or danger and increases heart rate and blood pressure. None of these hormones specifically influence sodium reabsorption in the kidneys.
