a.
To indicate:
The target area in nephron and the actions of the following hormones a. Antidiuretic hormone, b. Aldosterone c. Atrial natriuretic hormone.
Introduction:
The kidney is a complex excretory organ made up of repeating units called nephrons. Each nephron has a loop that penetrates into a deep portion of kidney, medulla. There are approximately one million nephrons in each kidney in the body. Nephron is divided into two parts, renal corpuscles and renal tubules. Renal corpuscle includes glomerulus and Bowman’s capsule whereas renal tubule includes proximal convoluted tubule, loop of Henle, distal convoluted tubule and collecting duct.
b.
To indicate: The target area in nephron and the actions of the aldosterone.

- Which of the following does not contribute to the process of filtration? (a) active transport by epithelial cells lining renal tubules (b) large surface area for filtration (c) low permeability of glomerular capillaries (d) high hydrostatic blood pressure in glomerular capillaries (e) podocytesarrow_forwardBlood pressure forces water and small solutes out of blood and into nephrons during ________. a. glomerular filtration c. tubular secretion b. tubular reabsorption d. both a and carrow_forwardWhich of the following does not contribute to the high salt concentration in the interstitial fluid of the kidney medulla? (a) active transport of sodium from the upper part of the ascending limb (b) diffusion of salt from the ascending limb of the loop of Henle (c) reabsorption of salt from various regions of Bowmans capsule (d) counterflow of fluid through the two limbs of the loop of Henle (e) diffusion of urea out of the collecting ductarrow_forward
- The afferent arteriole delivers blood to the (a) renal artery (b) efferent arteriole (c) renal vein (d) capillaries of the glomerulus (e) peritubular capillariesarrow_forwardDescribe (and label on a diagram) the structures of a nephron (including associated blood vessels) and give the functions of each structure.arrow_forwardA patient has an ADH-secreting pulmonary carcinoma (syndrome of inappropriate ADH secretion). As a result of unregulated ADH secretion, you would expect to find: a. retention of water resulting in volume expansion b. low urinary osmolality c. increased renal sodium reabsorption d. high serum sodium concentration e. b and c A 25-year old woman develops a nonfunctional hypothalamic tumor that results in a complete inability to produce oxytocin. The most likely pathological response to this deficiency is: a. inability to ovulate b. amenorrhea c. hypertension d. inability to lactate normally e. inability to deliver a child vaginallyarrow_forward
- Which of the following is TRUE concerning renal handling of potassium? a. A high potassium meal will cause enhanced basolateral uptake via sodium-potassium pumps b. Most potassium reabsorption occurs at the distal tubules c. Aldosterone enhances potassium reabsorption at the proximal tubule d. Potassium is not filtered, so urinary excretion of potassium will only occur by stimulating potassium secretion e. Decreased extracellular potassium concentration increases aldosterone production and thereby reduces potassium secretionarrow_forwardA pt was born with a rare genetic disorder in which the proximal tubules of her nephrons express half the number of aquaporins as normal. What will result? A. reduced reabsorption of water, although as much reabsorption of Na+ as is typical? b. reduced reabsorption of water, Na+ and glucose in the proximal tubules? c. Reduced reabsorption of both water and Na+ in equal proportions? D. Reduced reabsorption of all materials in the proximal tubules.arrow_forwardIf aldosterone was inhibited, which of the following would be affected? A. Na+/K+ pump activity in the descending limb of Henle. B. Na+ reabsorption in the proximal tubule. C. Transcellular transportation in the distal convoluted tubule. D. K+ reabsorption in the proximalarrow_forward

A. from the capillaries of the vasa recta into the renal tubule lumen B. from the collecting duct into the ureter C. from the renal artery into the collecting duct D. from the renal tubule lumen into the surrounding interstitial fluid E. from the afferent arteriole into the glomerulusarrow_forwardwhich of the following correctly shows the order in which the filtrate moves through the structures of the nephron? a. proximal tubule - distal tubule - collecting duct - loop of Henle b. collecting duct - loop of Henle - proximal tubule - distal tubule c. distal tubule - loop of Henle - proximal tubule - collecting duct d. proximal tubule - loop of Henle - distal tubule - collecting ductarrow_forwardWhich is the correct answer for kidney from the following statement(s)? Local production of prostaglandin in kidney protects kidney from ischemic injury. a. Sympathetic stimulation has no effect on afferent and efferent arterioles so that kidney is protected from undergoing ischemia. b. Kidney is vulnerable to ischemic injury. C. d. NSAID inhibits production of angiotensin I. Only (a) and (c) are CORRECT e.arrow_forward
