Verified step by step guidance

Understand that the glomerular filtration rate (GFR) is a measure of kidney function.

Recognize that GFR specifically refers to the volume of blood plasma that is filtered by the glomeruli in the kidneys per minute.

Differentiate GFR from other kidney functions such as urine production rate, water reabsorption rate, and solute concentration in urine.

Identify that GFR is a critical indicator of renal health, often used to assess how well the kidneys are filtering blood.

Conclude that the correct description of GFR is the volume of blood plasma filtered by the kidneys per minute, as it directly relates to the filtration process in the glomeruli.
