Question

Which renal structures are at the highest risk for ischemia during episodes of reduced blood flow?

a) Glomeruli
b) Proximal tubules
c) Collecting ducts
d) Loop of Henle

Answer 1

The renal structures at the highest risk for ischemia during episodes of reduced blood flow are the proximal convoluted tubule, descending loop of Henle, ascending loop of Henle, and collecting ducts.

Step-by-step explanation:

The renal structures at the highest risk for ischemia during episodes of reduced blood flow are the proximal convoluted tubule, descending loop of Henle, ascending loop of Henle, and collecting ducts.

During episodes of reduced blood flow, these structures may not receive enough oxygen and nutrients, leading to a risk of ischemia (cellular damage due to lack of blood supply).

For example, the proximal convoluted tubule is one of the first renal structures to receive blood flow after filtration occurs in the glomerulus. If blood flow to the kidneys is compromised, the proximal convoluted tubule may be at a higher risk of ischemia.
