QuestionChoice
This is incorrect. Damage to the afferent arteriole is more likely to affect glomerular blood flow and filtration pressure rather than causing haematuria.

Afferent arteriole
QuestionChoice
This is correct. This vignette is consistent with post-streptococcal glomerulonephritis, as indicated by the recent sore throat and haematuria. Haematuria (blood in urine) is often associated with damage to the glomerular basement membrane, a critical filtration barrier within the glomerulus. When the basement membrane is compromised, red blood cells can leak into the urine.

a
Glomerular basement membrane
QuestionChoice
This is incorrect. Damage to the efferent arteriole can impact glomerular haemodynamics but is less likely to directly result in haematuria.

d
Efferent arteriole
QuestionChoice
This is incorrect. Damage to podocytes can also lead to haematuria, but it is not the primary structure associated with blood in the urine. Podocytes play a role in maintaining the integrity of the glomerular filtration barrier.

b
Podocytes
QuestionChoice
This is incorrect. Damage to Bowman's capsule is more likely to affect the initial collection of filtrate but is less likely to be the primary cause of blood in the urine.

A 13 year old boy presents to the General Practitioner with his father. The boy has noticed blood in his urine but denies any pain. His father describes him as 'coming down with a cold and sore throat' 3 days previously. He is usually fit and well with no past medical history and no regular medications.

Which of the following structures of the glomerulus is most likely damaged?
a
