What is the difference between aldosterone and adh




















Aldosterone, like other steroidal hormones like cortisol, comes from the adrenal cortex the outer layer of the adrenal gland. ADH is synthesized in the hypothalamus while aldosterone is made in the adrenal cortex. ADH conserves water directly through its reabsorption while aldosterone conserves water indirectly through the reabsorption of sodium. Cite APA 7 ,. Difference Between Similar Terms and Objects.

It stimulates the absorption of sodium by the nephron to maintain water and salt balance. It increases the NaCl and water absorption capacity of the kidney by making an osmotic pressure. It is discharged in response to hypertonicity of the blood and in response to cholecystokinin. Save my name, email, and website in this browser for the next time I comment.

Chemical Structure of Aldosterone. Antidiuretic hormone ADH plays an important role to maintain osmoregulation of the body by controlling the amount of urine formation. With the small dose, ADH increases re-absorption of water from the renal tubules thus decreases the volume of excretory urine antidiuresis. It causes diabetes insipidus due to a lack of ADH. It is a condition in which a large volume of water is consumed and then lost by frequent excretion of dilute urine dieresis. It raises the blood pressure by causing arteriolar and capillary constriction with a large dose of ADH.

It also stimulates plain muscles of urinary bladder , ureter, intestine, uterus, etc. Role of Antidiuretic hormone ADH. Functions of Aldosterone.

Kidney reabsorbs and saves more water and makes urine more concentrated. Aldosterone is a steroid hormone. In fact, it is the main mineralocorticoid hormone made in zona glomerulosa of the adrenal cortex in the adrenal gland. It works on distal tubules and collecting ducts of our kidneys. It is essential for the reabsorption of water and conservation of sodium ions. Aldosterone is released to the blood in response to increased K in serum, decreased Na in serum and low renal perfusion.

Aldosterone increases the activity of sodium and potassium pumps and influences the reabsorption of sodium and excretion of potassium. So, this, in turn, influences the water retention or loss, blood pressure and blood volume. Moreover, aldosterone is a part of the renin—angiotensin—aldosterone system. ADH is a peptide hormone made in hypothalamus while aldosterone is a steroid hormone made in the adrenal cortex.

So, this is the key difference between ADH and aldosterone. Besides, the ADH is a peptide composed of nine amino acids, while the aldosterone is a steroid made of cholesterol. Therefore, this is the basic structural difference between ADH and aldosterone. Moreover, ADH works via increasing the water permeability by opening pores in kidney epithelial cells, while aldosterone works via increasing the activity of sodium pumps.

Also, another difference between ADH and aldosterone is the release of each hormone.
