The Urinary System

The Bowman’s capsule and glomerulus make up the:

• Renal corpuscle
• Loop of Henle 
• Renal tubule system 
• Collecting duct

The factor that forces substances to be filtered through the glomerular capillary wall is: 

•  The osmotic pressure of blood 
• The hydrostatic pressure of blood 
• Aldosterone
• Renin

 The portion of the nephron that is attached to the collecting duct is the:

• Glomerulus
• Distal convoluted tubule
•   Proximal convoluted tubule 
• Loop of Henle

All of the following are functions of the kidneys, except: 

•  Regulation of blood protein levels
• Regulation of blood pH
• Secretion of erythropoietin 
• Maintenance of ion balance

At the beginning of the “plumbing system” of the urinary system, urine leaving the renal papilla is collected in the cuplike structures called: 

• renal columns. 
• renal pyramids.
• calyces. 
• ureters.

Substances travel from the glomerulus into Bowman capsule by the process of:

• diffusion.
•  active transport.
• filtration.
• osmosis.

Of all the blood pumped per minute by the heart, approximately ____ goes through the kidneys

• 1/5
• 1/3
• 1/2
• 3/4

Reabsorption, as performed in the kidney, may be defined as the:

• movement of molecules out of the tubule and into the peritubular blood.
•  movement of molecules out of the peritubular blood and into the tubule for excretion
• movement of water and solutes from the plasma in the glomerulus, across the glomerular-capsular membrane, and into the capsular space of Bowman capsule. 
• volume of plasma from which a substance is removed by the kidney per minute

Under normal conditions, most nutrients are reabsorbed in which portion of the nephron?

• Proximal tubule
• Ascending loop of Henle
• Distal tubule
• Collecting tubule

Filtrate in which part of the nephron tubule has the highest osmolality?

• Proximal tubule
• Ascending loop of Henle
• Descending loop of Henle
•  Distal tubule
