Which nephron part do you think will be most at risk of damage due to chronic hypertension? which nephron part do you think will be most at risk of damage due to chronic hypertension? renal corpuscle collecting duct nephron loop proximal convoluted tubule?

The correct answer for the question is the Renal corpuscle.
Renal corpuscle, also called the malphigian body, filtration unit of vertebrate nephrons functional units of the kidney. It consists of a knot of capillaries surrounded by a double walled capsule that opens into a tubule.
