Urinary system quiz

What is a nephron?

• hormones secreted by kidney

• combination of glomerulus and renal tubule where filtration, reabsorption, and secretion take place in the kidney

• nitrogenous waste excreted in urine

• hollow muscular sac hat holds urine

What is the glomerulus?

• tiny ball of hormones located between the afferent & efferent arterioles

• tiny ball of blood vessels/capillaries located between the afferent & efferent arterioles

• tiny ball of arteries located between the afferent & efferent arterioles

• tiny ball of veins located between the afferent & efferent arterioles

What best describes filtration?

• process where all substances pass through a filter

• tube for injecting or removing fluid

• process where some substances but not all pass through a filter

• waste
