The hormone aldosterone functions to promote the?
Reabsorption of Sodium
The hormone that influences sodium reabsorption in the kidney is?
aldosterone
What conditions promote increased sodium or hypernatremia?
diabetes insipidus (water loss by the kidneys), Cushing's disease, and hyperaldosteronism (increased sodium reabsorption).
Which hormone plays a central role in determining the rate of sodium reabsorption and potassium secretion?
Aldosterone
How does sodium reabsorption affect water reabsorption?
If sodium reabsorption increases, water reabsorption increases as well.
What may happen to the sodium content in the urine of a person who increased his or her intake of sodium chloride?
the sensory division of pns will detect the change of high amount of sodium.and ADH antidiuretic hormone will be released for the reabsorption of sodium.and kidneys will filter sodium and make the urine appropriate to eliminate.
How does the reabsorption of sodium and water from the renal tubules increase blood volume?
When blood volume is low, sodium reabsorption in the kidneys is stimulated. The increased sodium increases osmotic pressure, causing water to be reabsorbed with the sodium. The reabsorbed water is added to the plasma, thus increasing blood volume.
What is the purpose of aldosterone?
The major target of aldosterone is the distal tubule of the kidney, where it stimulates exchange of sodium and potassium. Three primary physiologic effects of aldosterone result:Increased resorption of sodium: sodium loss in urine is decreased under aldosterone stimulation.Increased resorption of water, with consequent expansion of extracellular fluid volume. This is an osmotic effect directly related to increased resorption of sodium.Increased renal excretion of potassium.Knowing these effects should quickly suggest the cellular mechanism of action this hormone. Aldosterone stimulates transcription of the gene encoding the sodium-potassium ATPase, leading to increased numbers of "sodium pumps" in the basolateral membranes of tubular epithelial cells. Aldosterone also stimulates expression of a sodium channel which facilitates uptake of sodium from the tubular lumen.
When aldosterone is absent sodium reabsorption in the nephon is increased?
When aldosterone is absent, Na+ reabsorption in the nephron is greatly reduced, and as 30-40g of sodium can be lost in the urine daily. The answer is decreased. Site: Anatomy and Physiology Eighth Edition by Seeley Stephens Tate
Which hormons used to promote Na reabsorption by kidneys?
aldosterone, antidiuretic hormone (ADH, or vasopressin), atrial natriuretic peptide (ANP), and other hormones.The three hormones responsible for regulating renal sodium and chloride ion reabsorption are;1. Aldosterone2. Atrial natriuretic peptide or ANP3. Angiotensin II
What is the hormone that is important in regulation of sodium water balance?
Aldosterone is the hormone produced by the adrenal gland which is responsible for salt (sodium) regulation of the body.
What hormone regulates sodium re absorption in the distal convoluted tubule?
Sodium and potassium levels are controlled by secreting K+ and absorbing Na+. Sodium absorption by the distal tubule is mediated by the hormone aldosterone. Aldosterone increases sodium reabsorption.
