Question

certain substances, like caffeine and citrus juices, are classified as diuretics. this means that they cause diuresis in the kidneys. what effect will diuretics have on the urinary system? multiple choice they increase volume of urine excreted they decrease volume of urine excreted. they increase amount of urea produced. they decrease gfr.

Explanation:

Diuretics act on the kidneys to increase urine output. They do not directly affect urea production (which occurs in the liver). Also, they do not decrease the glomerular filtration rate (GFR) in a way that would reduce urine volume. The main action is to increase the volume of urine excreted.

Answer:

They increase volume of urine excreted.
