Urinary System

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

What would you find inside the glomerulus?

• Urea
• Urine
• Blood
• Lymph

What C-shaped structure in the nephron surrounds the glomerulus?

• Bowman's capsule
• bladder
• renal pelvis
• hilum

What is the function of ADH?

• decreases reabsorption of water and salts
• increases reabsorption of hydrogen ions
• increase reabsorption of salts
• increases reabsorption of water 

The proximal convoluted tubule in the nephron aids in:

• Reabsorption
• Secretion
• Filtration
• Urination

A hollow muscular sac that holds up to 500 mL of urine:

• Bladder
• Kidney
• Ureter
• Urethra
