When sodium ions are reabsorbed in response to the action of aldosterone what do potassium ions do?
secreted
Which of the following does not impact how much sodium is reabsorbed?
Transport maximum of the renal proximal tubule
Where is potassium reabsorbed and secreted?
The absorption of sodium affects the secretion of potassium by making it more difficult for the potassium to be permeable by blocking the areas it travels through.
Kidney has what electrolytes that balance blood?
Sodium and potassium are the electrolytes that maintain the proper blood balancing. These electrolytes are some times reabsorbed from the consumed food during the process of purification in the kidney.
How does urine differ from the original filtrate?
From the original filtrate, a lot of much needed electrolytes (Sodium e.t.c) are reabsorbed (absorbed back into blood), a few substances secreted further into the urine, then loads of water reabsorbed to fine tune body water to exactly how much you need(as much as possible), making urine far more concentrated than the original filtrate.
Where does sodium get reabsorbed?
in your penis
What is the the substances reabsorbed in the DCT?
Sodium and Chloride
Whenever sodium ions are reabsorbed through the wall of the renal tubule be active transport chloride ions are?
reabsorbed by active transport
When sodium ions are reabsorbed in response to the action of aldosterone what do potassium ions do?
secreted
What does not impact how much sodium is reabsorbed?
Transport maximum of the renal proximal tubule
Which of the following does not impact how much sodium is reabsorbed?
Transport maximum of the renal proximal tubule
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 removed at the proximal convoluted tubule?
About 90 % of the fitered sodium chlorid in glomerulus is reabsorbed in proximal convoluted tubules.
What is reabsorbed by the proximal convoluted tubule cells?
Glucose is totally reabsorbed via secondary active transport through co-transport channels driven by the sodium gradient out of the nephron
When sodium ions are reabsorbed because of aldosterone what do potassium ions do?
Aldosterone works to reabsorb sodium ions (and thereby water) at the expense of losing potassium ions. Ref: Marieb & Mitchell. A&P (9th ed.).
Where is potassium reabsorbed and secreted?
The absorption of sodium affects the secretion of potassium by making it more difficult for the potassium to be permeable by blocking the areas it travels through.
What are examples if substances that are reabsorbed into the blood?
Blood reabsorbs : glucose, amino-acids, sodium ions, potassium ions, chlorine ions, water etc.
