Question

Which of the following statements is true?

Answer 1

Answer:

The correct answer is: D) The kidneys are paired organs that regulate water and electrolyte balance in terrestrial vertebrates.

Explanation:

The kidneys are the organs that control, for example, the volume of body fluid compartments, acid-base balance, and electrolyte concentrations. These organs are also key to eliminate the toxins from the body.

The kidneys are always two (when not is because of a pathology or the surgical removal of one of the two) and are present in vertebrates.

The kidneys do not regulate blood glucose. That is the job of the pancreas through two hormones called insulin and glucagon.

The kidneys do not remove nitrogenous wastes (urea) from the urine, instead they filtrate these wastes from the blood for these to be excreted through urine.
