How does ADH affect the concentration of potassium in urine?
Affects the concentration of potassium in the urine by controlling the amount of water in the urine.
How does aldosterone modify the chemical composition of urine?
The higher the aldosterone levels, the more sodium that is reclaimed and the more potassium that is lost.
How does the addition of ADH affect the concentration of potassium in the urine?
Anti-diuretic hormone (ADH) causes water to be absorbed from the urine back into the body. Everything else in the urine, including electrolytes such as potassium, is concentrated.
Why drugs may affect urine concentration?
Drugs may affect urine concentration because it can make your urine a destorted colour and the production will come out more darker and inefficent.
What is the role of aldosterone?
Aldosterone promotes water retention and reduces urine volume
What causes the concentration of urea to be higher in the urine than in the filtrate?
During reabsoption most of the water exits the nephron and enters the interstitial fluid. This increases the concentration of ions such as potassium in the nephron. In the collecting duct (at the very end) very little water is left and the concentration of potassium, sodium, etc ions rises (including urea). This is why urine is acidic.
How does aldosterone affect the blood volume?
renin is created by the kidneys which in turn converts angiotensin 1 to angiotensin 2 this stimulates the formation of aldosterone to excrete urine. I would say that it increases the urine volume to decrease the plasma volume.
What hormone increases excretion of electrolytes by the kidneys?
Aldosterone, secreted by the zona glomerulosa of the adrenal gland, will make your kidneys excrete more potassium and acid in urine, but it will make your kidneys absorb more sodium.
What hormone causes the kidneys to reabsorb sodium and water?
Vasopressin and ANP reduce water loss in urine. I don't remember which hormone reduces sodium loss in urine.
What tests comprise the diagnosis for hyperaldosteronism?
Blood and urine tests may be conducted to check for levels of aldosterone, potassium levels, or renin activity. A computed tomography scan (CT scan) may be ordered to detect tumors
Does Both ADH and aldosterone tend to reduce the amount of urine produced?
yes
What hormone that decides dilute or concentrated urine will be formed?
aldosterone is the hormone that decides this
