When sodium ions are reabsorbed through he we all of the renal tubule by active transport, chloride ions are

• reabsorbed by passive transport

• reabsorbed by active transport

• secreted by active transport

• secreted by passive transport

The counter current mechanism functions primarily in the

• renal corpuscle

• proximal convoluted tubule

• distal convoluted tubule

• nephron loop

The hormone ADH promotes water reabsorption through the wall of the

• distal convoluted tubule and collecting duct

• proximal convoluted tubule and collecting duct

• ascending limb of the nephron loop

• descending loop of the nephron loop

Most hydrogen ions are secreted

• passively into the proximal convoluted tubule

• passively from the distal convoluted tubule

• actively into the entire renal tubule

• actively from the distal convoluted tubule

Which of the following would increase the rebate of glomuler filtrationrate

• decrease blood pressure

• increase blood pressure

• constricted afferent arteriole

• dialated efferent arteriole

In which of the following regions of the nephrons is water actively transported

• proximal convoluted tubule

• descending limb of the nephron loop

• collecting duct

• paratubular capillaries

• distal convoluted tubule

Which of the following is an abnormal constituent of urine?

• urea

• uric acid

• creatinine

• water

• none of the above

Which choice describes the counter current mechanism of the nephron loop

• water moves out of the ascending limb; sodium moves in the ascending limb

• water moves int he ascending limb; sodium moves out of the ascending limb

• water moves out of the descending limb; sodium moves out of the ascending limb

• water moves in the descending limb; sodium moves out of the descending limb

In the disease gout plasma has excess

• uric acid

• urea

• calcium ions

• amino acids

• hemoglobin

As a result of very low arterial blood pressure, glomuler hydrostatic pressure

• rises and filtration increases

• rises and filtration decreases

• drops and filtration increases

• drops and filtration decreases
