Question

3Refer the given figure showing structure of Malphigian corpuscle. To facilitate ultrafiltration through glomerular capillaries ________.

• A. part 'D' is narrower than part 'A'
• B. part 'A' is narrower than part 'D'
• C. part 'C' is narrower than part 'D'
• D. part 'B' is narrower than part 'D'

Answer 1

Answer: (A)

part 'D' is narrower than part 'A'

In the given diagram of the Malpighian corpuscle, A shows the afferent arteriole and D shows the capillaries of the glomerulus. The capillaries are narrower than the arterioles in order to facilitate ultrafiltration through glomerular capillaries.

So the correct answer is 'part 'D' is narrower than part 'A'.'
