The original phrasing of the "Extra" field implies that an increase in GFR by itself directly reduces Na⁺ reabsorption, which is mechanistically false. In reality, proximal and distal nephron segments adjust via hormonal feedback (ANP, decreased RAAS) to achieve natriuresis. Without these signals, a higher GFR alone would largely be compensated by glomerulotubular balance, leaving Na⁺ reabsorption fractionally unchanged.
I propose the alternative mechanistic chain:
"ANP release → vasodilation of afferent arteriole & mild inhibition of RAAS → direct inhibition of distal Na⁺ reabsorption → natriuresis"
Thank you so much for all you suggestions. They really are insightful! But to ensure that they have the maximum chnace of being approved make sure you do these three things:
1. Always attach and amboss or uworld or other accepted source. https://community.ankihub.net/t/anking-step-deck-submission-guidelines/166504
2. Revert your change tag suggestions since they are not part of the edit
3. Directly make the edit as opposed to proposing it in the rationale.
Again! we really appreciate your work!
