TOPIC 1: GLOMERULAR FILTRATION RATE AND REGULATION
5 Questions • 19.2% of Exam • This topic covers the mechanisms and factors influencing the glomerular filtration rate (GFR).
QUESTION 1
Each of the following statements are true regarding control over the GFR except:
Correct Answer: The RAA responds when blood pressure rises above normal limits.
(false b/c the RAA responds when blood pressure drops below normal limits.)
Rationale: The Renin-Angiotensin-Aldosterone (RAA) system responds to low blood volume or decreased blood pressure
by increasing blood pressure through vasoconstriction and fluid retention, thereby correcting the drop in blood pressure. By
responding to low blood pressure, the statement that the RAA system responds when blood pressure drops below normal
limits is a correct exception to the assertion that it only responds when blood pressure rises above normal limits.
QUESTION 2
A patient is said to be in stage 3a kidney disease. What would you expect their GFR to
be?
Correct Answer: 70 ML/min/1.73m2.
Rationale: Stage 3a kidney disease is a classification based on the glomerular filtration rate (GFR) in the Kidney Disease
Improving Global Outcomes (KDIGO) staging system, which indicates a GFR of 45-59 mL/min/1.73m2. The "1.73m2" in the
denominator accounts for the body surface area, making this measurement standard across patients of varying sizes.
QUESTION 3
In the nephron, the mass of capillaries surrounded by an epithelial capsule that opens
into a tubule is collectively referred to as the _______.
Correct Answer: Renal corpuscle
(glomerulus also accepted as correct)
Rationale: The term "renal corpuscle" accurately describes the structure in question because it consists of a cluster of
capillaries, known as the glomerulus, surrounded by a double layer of epithelial cells called the Bowman's capsule. This
anatomical arrangement forms the primary filtration unit of the nephron, where blood is filtered to produce urine.
