you want the kidney to excrete more Na+ in the urine,what do you want the blood flow to do?
why does the kidney receive 1/4 of cardiac output?
Drugs that increase urine flow (diuretic drugs) are often employed in the treatment of hypertension (high blood pressure) or other disease states. Three physiological categories of such drugs are ones that (i) function as loop diuretics, (ii) inhibit the action of aldosterone, and (iii) block Na+ channels in the collecting ducts. Explain why each of these categories would be expected to increase Na+ excretion and urine flow.

- A kidney stone blocking a ureter would interfere with urine flow to which organ? Why would the pain occur in waves?arrow_forwardIf urine/filtrate is hyperosmotic to the interstitial fluid, fluid would go from the interstitial fluid to the urine/filtrate. How does this conserve water? Wouldn’t this NOT conserve water but rather increase the amount of water that is excreted via urine?arrow_forwardWhy can’t the kidneys just excrete the filtered plasma without adjusting it’s content?arrow_forward
- Why is excretion important in order to achieve osmotic balance?arrow_forwardPressure in the renal artery is 100 mm Hg and the pressure in the renal vein is 50 mm Hg. The resistance of the afferent arteriole equals 0.5 mm Hg•min/L and the resistance of the efferent arteriole equals 0.5 mm Hg•min/L. What is the pressure in the glomerulus?arrow_forwardDraw a flow chart of blood supply to the kidney? (c) write a note on formation of urine by the kidney? With explanationarrow_forward
- Explain in your own words when Renin release is stimulated by the kidneyarrow_forwardHow does the secretion of ADH affect urine volume and urine concentration? What factors increase the release of ADH from the posterior pituitary gland? How would you alter the secretion of aldosterone and ADH to reabsorb more sodium without reabsorbing large quantities of water from the filtrate?arrow_forwardTwo physiology students are having a disagreement about renal function. Student X says that the kidneys work harder when you eat a high salt diet while student Z says that they work harder when you drink lots of water. Who is right, and why?arrow_forward
- Is this following statement correct? In the kidney, vasoconstriction of the afferent arteriole increases glomerular filtration rate, because hydrostatic pressure in the glomerular capillaries increases (much like putting your thumb over the end of a garden hose increases the pressure and causes the water to exit the hose with greater velocity and travel a greater distance).arrow_forwardIf blood pressure drops in a patient in shock as a resultof a severe injury, how would you expect urine volume to change? Why?arrow_forwardFrom the previous question, In which section of the kidney tubules does this potassium movement occur? Is that movement passive or active?arrow_forward
