Ch 18 Urinary System

The inner region of the kidney

• renal cortex

• renal medulla

• renal pelvis

• hilum

Divides the interior of the kidney into cone-shaped sections

• renal medulla

• renal pelvis

• renal pyramids

• renal columns

The outer region of the kidney

• renal cortex

• renal medulla

• renal pelvis

• hilum

Which statement about the location of the kidneys is correct?

• The kidneys lie underneath the 10th rib.

• The kidneys lie anterior to the parietal peritoneum.

• The kidneys lie against the anterior abdominal wall.

• The kidneys extend from the level of the T12 vertebra to the L3 vertebra.

What is the filtration unit of the kidney called?

• glomerulus

• nephron

• renal pelvis

• renal papilla

Which of the following statements accurately describes the function of Bowman's capsule?

• Bowman's capsule captures fluid leaking out of the glomerulus and returns it to the peritubular capillaries.

• Fluid that filters out of the glomerulus collects in between the two layers of Bowman's capsule and then flows into the renal tubule on the other side of the capsule.

• Bowman's capsule applies pressure to the glomerulus to increase the speed of filtration.

• Bowman's capsule applies pressure to the glomerulus to decrease the speed of filtration.

What is the renal tubule?

• A mass of capillaries that make up the glomerulus.

• Branches of the renal artery that supplies blood to the renal cortex.

• A collection of tubelike structures that leads away from the glomerulus.

• Tubelike structures that converge to form the ureter.

What substance is filtered by the kidneys?

• urine

• intracellular fluid

• blood

• tissue fluid

What factor drives filtration in the glomerulus?

• energy from ATP

• energy from glucose

• diffusion

• a pressure gradient

Which of the following correctly describes the flow of filtrate as it leaves Bowman's capsule?

• Collecting duct, proximal convoluted tubule, loop of Henle, distal convoluted tubule

• Loop of Henle, proximal convoluted tubule, distal convoluted tubule, collecting duct

• Proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct

• Distal convoluted tubule, loop of Henle, collecting duct, proximal convoluted tubule
