Question
has which of the following effects? Na* and K B) c) causes the urine to be more dilute D) 26. The thick segment of the ascending limb of the nephron loop is permeable to A) water but not urea. B) sodium ions but not potassium ions. C) sodium and potassium ions but not D) water but not salts. sodium, potassium, and chloride ions but not water. 27. A) increases water and sodium reabsorption. increases increases urine output but not urine concentration. increases the volume and concentration of the urine. reduces the glomerular filtration rate. water reabsorption but not sodium reabsorption. E) 28. Atrial natriuretic factor is secreted in response to A) angiotensin. B) hypertension. C) hypotension D) aldosterone E) hyponatremia. 29. The cells of the distal convoluted tubule in contact with the afferent arteriole are A) the macula densa. B) the mesangial cells the podocytes. the juxtaglomerular cells the juxtamedullary cells net filtration pressure of a blood capillary is the difference between olloid osmotic pressure and oncotic pressure. ood and interstitial hydrostatic pressures. od pressures at the arterial and venous ends. hydrostatic pressure and oncotic pressure. stitial pressure and oncotic pressureExplanation / Answer
25 ) E is the answer increases Na+ reabsorption and reduces K+ reabsorption
26 ) E is the answer Sodium moves by active transport and potassium and cl move by cotransport out of the ascending limb of the loop of Henle
27 ) B is the answer increases water reabsorption but not sodium
28 ) B is the answer when blood pressure increases ( hypertension )
29 ) D is the answer The juxtaglomerular apparatus consists of cells from the wall of the afferent arteriole and the distal convoluted tubule.
