Question

Assertion: Hemodialysis is done by artificial kidney in case of kidney failure.
Reason: Kidneys are vital organs of survival but one kidney can serve the
purpose.

(a) Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

(b) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.

(c) Our Assertion is true but the Reason is false.

(d) The statement of the Assertion is false but the Reason is true.

Answer 1

Answer:

both a and r are true but r is not the correct explanation of a

Answer 2

Both statements are correct but reason does not explain assertion.

• Haemodialysis is the process by which nitrogenous wastes are artificially removed from the body when kidney failure occurs.
• An 'artificial kidney' is used which consists of a tube which takes blood containing nitrogenous wastes from the patient's body and deposits in a tank filled with a liquid of same composition as that of blood minus nitrogenous waste.
• This creates a concentration gradient which forces nitrogenous waste to move out of the blood, which is then released back into the patient's bloodstream.
• Kidneys are vital organs but a human being can survive with just 1 functional kidney as well.

Hence, option (b) The Assertion and Reason are correct but Reason is not the correct explanation of the Assertion is the correct option.
