The Urinary System

The elimination of urine (micturition) is which process?

• Secretion

• Filtration

• Reabsorption

• Excretion

#2 is indicating which structure?

• Renal pelvis

• Urethra

• Bladder

• Ureter

#4 Indicates which structure:

• Renal medulla

• Urethra

• Ureter

• Nephron

Which of the following is NOT a function of the urinary system?

• Regulate blood volume

• Regulate ion/ mineral levels in the blood

• Maintain pH balance

• Store and transport calcium

Where does FILTRATION take place in the nephron?

• Glomerulus

• Bowman's Capsule

• PCT

• Collecting Duct

Urine production takes place in the:

• nephrons
• bladder
• ureter
• renal pelvis

The correct order for the renal tubules is:

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

In homeostasis, the kidney regulates the:

• levels of electrolytes 
• amount of water in the body
• pH
• all of the above

Which stage of urine production involves returning water, nutrients, and electrolytes to the bloodstream?

• filtration
• excretion
• secretion
• reabsorption 

Which stage of urine production involves the removal of substances from the bloodstream?

• reabsorption
• excretion
• filtration
• secretion
