Question

3 ways the endocrine system works to regulate kidney function.

Answer 1

The first way is through RAAS mechanism renin angiotensin aldosterone system in the hormonal Mechanism which regulates blood pressure fluid and electrolytes balance.The Renin is the Hormone secreted by juxtaglomerular cells of kidney.The renin converts the protein angiotensin produced in the liver to angiotensin-1.The angiotensin 1 is converted to angiotensin 2 by the angiotensin converting enzyme whis present in the lungs.The angiotensin 2 has direct vasoconstriction effect which causes the increase in Blood pressure.The mineralocorticoid aldosterone is produced when there is decresed blood pressure.The aldosterone increases the blood pressure by absorption of Na+ and water from Collecting duct of kidney.

Thesecond way is ADH is the antidiuretic hormoneor vasopressin which is secreted by posterior pitutary the ADH acts on distal convoluted tubule and collecting duct where it absorbs water thus increases the blood pressure and increases the blood flow to the kidney thus increases the glomerlular.Erythropoitein is the hormone produced by the kidney it plays a key role in the production of red blood cells which carries oxygen from lungs to rest of the body.

Third way paratharmone produced by parathyroid glands stimulate kidney for the production of hormone 1,25 dihydrovitamin D3(calcitriol). Calcitriol increases renal tubular reabsorption of calcium from glomerlular filterate thud preventing Calcium loss in the urine.
