NEET 2019, Biology Q78: Physiology of Excretion

NEET2019Paper 2019Biology
Q.

Use of an artificial kidney during hemodialysis may result in :

(a) Nitrogenous waste build-up in the body

(b) Non-elimination of excess potassium ions

(c) Reduced absorption of calcium ions from gastro-intestinal tract

(d) Reduced RBC production

Which of the following options is the most appropriate?

  1. A

    (a) and (b) are correct

  2. B

    (b) and (c) are correct

  3. C

    (c) and (d) are correct

  4. D

    (a) and (d) are correct

Solution

a and b statements are incorrect because dialysis eliminates urea and potassium from the body whereas, c and d are correct. As phosphate ions are eliminated during dialysis, along with that calcium ions are also eliminated. So, there will be reduced absorption of calcium ions from gastrointestinal tract. RBC production will be reduced, due to reduced erythropoietin hormone.
