QuestionSBA
QuestionChoice
This is incorrect. Whilst the actions of ANP were correctly described, ANP is released from the atria, not the ventricles.

e
Increased venous return stimulates ANP release from the ventricles. This travels to the kidney to increase the GFR and reduce Na+ reabsorption
QuestionChoice
This is incorrect. ANP is released to increase Na+ excretion from the kidney. This is done by increasing the GFR, not decreasing it.

b
Increased venous return stimulates ANP release from the atria. This travels to the kidney to decrease the GFR and reduce Na+ reabsorption
QuestionChoice
This is incorrect. ANP is released to increase Na+ excretion from the kidney. This is done via decreasing Na+ reabsorption, not increasing it.

c
Increased venous return stimulates ANP release from the atria. This travels to the kidney to increase the GFR and increase Na+ reabsorption
QuestionChoice
This is correct. When the circulating volume is high, the elevated venous return results in increased atrial filling which stimulates ANP release. ANP then acts on the kidney to increase Na+ excretion. This is done by increasing the GFR and reducing Na+ reabsorption.
