Which term describes the age-related decline in the kidneys' filtering rate?

Explanation:
The key idea is how aging affects kidney filtration, measured by the glomerular filtration rate (GFR). With age, fewer functional nephrons and reduced renal blood flow lead to a slower filtering rate. This is described by a decreased GFR. Hypertension is high blood pressure and isn’t the term for this aging change. An increased GFR would mean more filtration than normal, which isn’t typical with aging. Proteinuria indicates protein leaking into urine, signaling kidney damage rather than the normal aging decline in filtration.
