AIIMS 2017 Zoology Arteries and Veins Assertion Reason Question
Read the Assertion and Reason carefully to mark the correct option from those given below Assertion: Arteries pump blood away from the heart at very low pressure. Reason: Arteries have thin wall with large lumen.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
Assertion is true but Reason is false
Both Assertion and Reason are false
Correct Answer
Detailed Explanation
Option B is correct because the assertion that arteries pump blood away from the heart at very low pressure is false; in fact, arteries carry oxygenated blood under high pressure due to the force generated by the heart's contractions. The reason provided is also true, as arteries do have relatively thick walls and a smaller lumen compared to veins, which helps withstand the high pressure, but it does not explain the assertion correctly. Option A is incorrect because the assertion is false, while option C is incorrect because the reason is true, and option D is incorrect as both statements are not false.
