Exam 12: The Urinary System

Match the urinary system feature with the correct characteristic by using the answer code: -reabsorbed actively and passively

If the plasma concentration of substance X is 200 mg/100 mL and the GFR is 125 mL/min,the filtered load of this substance is ____________________.

Where is water reabsorption under the control of vasopressin?

Which force favours glomerular filtration?

Which statement regarding tubular secretion is correct?

The micturition reflex controls bladder emptying in adults.

Which factor would reduce the net filtration pressure the most?

The amount of glucose filtered is directly proportional to the plasma glucose concentration at all plasma glucose concentrations.

The amount of glucose reabsorbed is directly proportional to the plasma glucose concentration at all plasma glucose concentrations.

The osmolarity of the medullary interstitial fluid always equilibrates with the descending limb of the loop of Henle.

Match the urinary system feature with the correct characteristic by using the answer code: -protein metabolite of skeletal muscle tissue

Autoregulation is important to prevent unintentional shifts in the GFR that could lead to dangerous imbalances of fluid,electrolytes,and wastes.

The micturition reflex is initiated by stimulating ____________________ receptors in the bladder.

What occurs after stimulation of the macula densa cells?

MATCHING Match the renal function with the correct characteristic by using the answer code: -glomerular filtration

Glomerular filtration occurs primarily by active transport.

Which statement regarding sodium reabsorption is INCORRECT?

Which statement regarding aldosterone secretion is INCORRECT?

Which plasma constituent is NOT regulated by the kidneys?

NaCl is actively transported from the descending limb of the loop of Henle to establish the medullary osmotic gradient.
