Question

question 6 (2 points) listen the kidneys receive more blood than expected for their size because they are very metabolically active their primary job is to cleanse the blood plasma of wastes they happen to lie very close to the heart their blood supply is not regulated they are supplied by four different arteries previous page next page page 6 of 42

Explanation:

The kidneys' main function is to filter waste from blood plasma. This requires a large blood - flow to process the necessary volume of blood for cleansing. Metabolic activity is not the main reason for high blood - flow relative to size. Proximity to the heart does not directly explain high blood - flow. The blood supply to kidneys is regulated, and the number of arteries is not the main reason for high blood - flow.

Answer:

their primary job is to cleanse the blood plasma of wastes
