Aldosterone
* acts on the kidney to make it hold on to sodium and water
  - kidneys to promote the retention of salt and water
  - upon the renal tubules to enhance sodium reabsorption
* also acts on the sweat ducts and colonic epithelium to conserve sodium.
* causes myocardial and vascular fibrosis
  - the kidneys to reclaim more sodium and thus water
* causes the kidneys to retain salt and water and to excrete potassium
  - and water which increases blood volume
* causes the kidneys to retain sodium and water, increasing plasma volume
  - reabsorption of sodium from the filtrate
* decreases salt excretion, which in turn can lead to high blood pressure.
* determines expression of sodium channels.
* enters the cell from the blood and binds to an intracellular receptor to form a complex.
* escape during angiotensin-converting enzyme inhibitor therapy in chronic heart failure.
* function of the inverse of the sodium intake as sensed via osmotic pressure.
* hormone in the body that increases androgen levels
  - released by the adrenal glands
* increases blood pressure
  - salt retention
* increases the kidneys' salt retention
  - loss of potassium in the kidneys
* increases the reabsorption of sodium from sweat
  - sodium and water reabsorption in the distal tubule
* is an example of a mineralocorticoid
  - another hormone that raises blood pressure
  - chemical compounds
  - classified as a mineralocorticoid hormone
  - concerned with the control of salt and water loss in the urine
  - corticosteroids
* is important in regulating minerals in the blood stream especially sodium and potassium
  - the pathophysiology of heart failure
  - involved in maintaining blood pressure as well as water and salt balance in the body
  - made by the adrenal glands, which are located above the upper portion of the kidneys
  - one example of a mineralocorticoid
  - produced and secreted by cells of the adrenal medulla
* is produced by cells in the cortex of the kidney
  - regulated by a the renin angiotensin system
* is secreted from the adrenal gland in the presence of increasing levels of potassium
  - in response to low extracellular potassium
  - the key regulator of sodium reabsorption in the kidney
  - unable to enter nontarget cells
  - yet another hormone that comes from the adrenal glands
* mineralocorticoid which controls mineral and water balance in the body.
* plays the primary role in adjustment of sodium excretion.
* produced by the adrenal glands controls the reabsorption of sodium ions by the kidneys.
* promotes sodium reabsorption, increasing blood volume and pressure.
* reduces baroreceptor activity in the dog.
* regulates fluid and electrolyte balance
  - salt and water levels which affects blood volume and blood pressure
  - the amounts of sodium and potassium in the blood
* saves salt.
* spontaneously converts to the hemiacetal form, which is active.
* steroid hormone produced by the adrenal cortex
  - in the adrenal gland that regulates sodium and potassium
  - secreted by the adrenal gland
* steroid hormone that causes the reabsorption of sodium
  - is produced and secreted by the adrenal glands
  - with major effects on sodium homeostasis
* stimulates the active resorption of sodium ions and the excretion of potassium ions
  - kidneys to resorb salt, ultimately functioning in retention of water
  - reabsorption of sodium while enhancing potassium secretion
* then acts on the kidney to make it retain sodium and water, and to get rid of potassium.
* usually increases sodium reabsorption in the kidney
  - promotes both sodium and water retention
* works in the cells of the cortical collecting duct, depicted at left
  - together with the kidneys to regulate the balance of minerals in the body
