What is aldosterone hormone?
Aldosterone is a hormone that is produced by the adrenal glands. It works primarily on kidney (renal) cells to help maintain the balance of fluids and electrolytes in our bodies. Its mainly works to control reabsorption of sodium and chloride and secretion of potassium and hydrogen. If aldosterone production is not functioning properly, there can be serious consequences to the heart, kidneys and electrolyte balance.
What effect does the hormone aldosterone have on the pH of blood plasma?
Short answer: In the kidney, aldosterone increases sodium retention, which increases potassium excretion, which increases H+ excretion, so aldosterone will tend to raise blood pH.Explanation:Aldosterone directly increases sodium retention in the kidney. ?Since all kidney cells have basolaterally located Na+/K+ ATPases, this will cause these exchangers to go into overdrive and dump more K+ into the cells. ?For those cells that have K+ channels, this will increase potassium excretion.Finally, certain cells in your collecting ducts have H+/K+ exchangers (either the alpha or beta intercalated cells). ?So if you have more K+ in the lumen, this will cause these exchangers to kick into overdrive and dump H+ into the lumen, which finally raises blood pH.
What is the effect of antidiuretic hormone on potassium concentration and excretion?
Antidiuretic hormone (ADH) decreases the amount of sodium in your body and when ever sodium levels go down potassium levels go up (same is true for visa versa) so the amount of Potassium should increase when there is an increase in ADH.
How does sodium reabsorption affect water reabsorption?
If sodium reabsorption increases, water reabsorption increases as well.
What hormones retains sodium in the body?
aldosterone retains salt at the distal convoluted tubule and the water follows
The hormone that influences sodium reabsorption in the kidney is?
aldosterone
What is the hormone that reduces the loss of sodium and water by the kidney?
Aldosterone
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.

What hormone promotes the reabsorbtion of sodium and potassium ions by the kidney?
When the macula densa in the distal tubules of the kidney sense a decrease in fluid volume, the renin-aldosterone system is activated. Aldosterone is the hormone responsible for sodium retention, causing water to be conserved.
what hormone promotes sodium ion by the kidney in order to increase blood pressure and blood volume?
Aldesterone
Why does taking a steroid hormone make you retain water?
A steroid hormone has a side effect of having mineralcorticoid activity. Specifically, it exerts similar effects to that of aldosterone. What aldosterone does is increase the amount of sodium that's reabsorbed by your kidney. With sodium, water comes along as well, hence the water retention from a steroid hormone.
What is the net result of the effect of aldosterone on the kidney nephron?
Sodium reabosorbtion increases, water follows, and ultimately blood volume is restored.

How the hormone epinephrine increases the pumping rate of the sodium-potassium exchange pump in skeletal muscles?
Na would decrease, K would increase
Does ADH promote secretion of sodium ions?
No! it doesn't. It just promotes your free water reabsorption in the distal tubules of the kidney. It increases the amount of aquaporines in the cell membrane, causing an influx of water in the medulla of the kidney. Sodium concentration of the urine will be higher because the urine is more concentrated. However, there isn't more sodium excreted.
Is the hormone responsible for increased sodium reabsorption?
anti diuretic hormone
