Exam 13: The Urinary System

Match the effects, labelled a. through c., with the statements. (Options may be used more than once or not at all.) -Increased aldosterone secretion __________ Na⁺ reabsorption.

Which of the following is NOT a function of the kidneys

Which of these plasma constituents is NOT regulated by the kidneys

Which of these statements does NOT refer to the tubular maximum (Tm)

A pure loss or gain of H₂O a.that is not accompanied by comparable solute deficit or excess in the body leads to changes in ECF osmolarity.

The afferent arteriole is the blood vessel that carries blood to the glomerular capillaries.

What is the normal glucose concentration in the plasma

In normal conditions, which portion of the renal tubules absorbs the largest amount of sodium

Match the correct statements about sodium reabsorption, labelled a. through c., with the characteristics. (Options may be used more than once or not at all.) -plays a critical role in the kidneys' ability to produce urine of varying concentrations and volumes

Filtrate does NOT pass through which of these structures

During acidosis, H⁺ secretion increases.

Which of the following pertains to the ascending limb of the loop of Henle

Match the chemicals, .labelled a. through f., with their correct characteristics. (Options may be used more than once or not at all.) -produced by the liver

Match the renal structures or activities with the correct characteristics, labelled a. through p. -proximal tubule

Which of these statements does NOT apply to the urinary bladder

If a kidney stone blocked the renal pelvis and consequently caused a buildup of fluid pressure in the tubules and Bowman's capsule, the net filtration pressure across the glomerular capillary membrane would increase.

What are the pathological effects of renal failure

Compare and contrast renal actions at the proximal and distal tubules.

Which statement applies to plasma clearance

Contraction of mesangial cells closes off a portion of the filtering capillaries, which leads to a decrease in GFR if the filtration pressure remains unchanged.
