Explain in your own words when Renin release is stimulated by the kidney
Step by step
Solved in 2 steps
- Drinking alcohol inhibits ADH secretion. What effect will drinking a beer have on the permeability of kidney tubules to sodium? To water?Diagram/flow chart the reactions and interactions of the renin-angiotensin-aldosterone pathway. What conditiion is the primary stimulus for its activation? What would hapen to renin secretion in a patient with chronic kidney failure?Those with chronic renal failure often have issues with anemia because the kidney cannot secrete sufficient levels of renin.
- Renal tubules cannot reabsorb HCO3–; yet HCO3–concentration in the tubular fluid falls while in the blood plasma itrises. Explain this apparent contradiction.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.The reabsorption of water, Cl–, and glucose by the PCT islinked to the reabsorption of Na+, but in three very different ways. Contrast these three mechanisms
- are both statements correct? In the absence of ADH, the kidneys produce dilute urine; renal tubules absorb more solutes than water. In the presence of ADH, the kidneys produce concentrated urine; large amounts of water are reabsorbed from the tubular fluid into interstitial fluid, increasing solute concentration of the urineThis is produced by the adrenal cortex influencing tubular reabsorption. - inulin - bicarbonate - glucose - creatinine - calcium - adenosine - chloride - renin - aldosteronetrue or false Aldosterone is required to restore water from loop of Henle, and reabsorption of Na+ from this segment is increased by ADH, allowing equilibration of water with the hyperosmotic interstitium
- Explain how the capacity (function) of the sodium potassium pumps found in the ascending loop of Henle enable the establishment of the medullary concentration gradient.When GFR is high, which primary autoregulatory mechanism is triggered in the kidney? Currently Selected : C A Vasoconstriction of efferent arteriole В Vasoconstriction of afferent arteriole C Vasodilation of afferent arteriole D Vasodilation of efferent arterioleWhich of the following is true of aldosterone?
