CAPD utilizes the _________ as a dialysis membrane.

Damage to the lumbar region of the spinal cord could impair micturition.

The __________ is the functional unit of the kidney.

Renal insufficiency often results from dialysis.

Inulin clearance gives a measurement of the glomerular filtration rate.

Since most filtered bicarbonate is reabsorbed,where does the bicarbonate come from that is used to compensate for acidosis?

Potassium secretion by the kidneys is only possible due to the action of aldosterone.

A decrease in blood pressure will cause an increase in GFR through sympathetic stimulation.

The apical membranes of the tubular cells are impermeable to bicarbonate.

The collecting duct is naturally impermeable to salt but permeable to water.

Hypertension and edema are often treated with diuretics.

Only about 20% of renal blood is filtered in one pass through the kidneys.

The primary filter to exclude proteins from the filtrate is the

The transport of water is always an active process.

People with diabetes mellitus have polyuria because

The ____ limb of the loop of Henle is impermeable to salt.

Na⁺ reabsorption is a(n)__________ process,while Cl^- reabsoprtion is a(n)__________ process.

Hemorrhage would induce

The osmotic diuretic mannitol inhibits salt and water absorption in the proximal convoluted tubule.

What is the order that filtrate must pass through to the glomerular capsule?
