Physiology revision with active recall
Physiology rewards understanding over memorising: if you can predict what happens next, you can answer almost any question. The best active recall questions ask you to reason through a change.
Example: from a lecture excerpt to questions
Stroke volume rises with end-diastolic volume (the Frank-Starling mechanism). On standing, venous return falls, arterial pressure drops briefly, and baroreceptors in the carotid sinus fire less, increasing sympathetic output and heart rate.
According to the Frank-Starling mechanism, which change increases stroke volume?
- A. A decrease in end-diastolic volume
- B. An increase in end-diastolic volume ✓
- C. An increase in afterload alone
- D. A decrease in venous return
Why: Greater filling stretches the ventricle, which contracts more forcefully. Less filling or higher afterload reduces stroke volume.
A healthy 22-year-old stands up quickly from lying down. What is the immediate compensatory response?
- A. Increased baroreceptor firing and bradycardia
- B. Decreased baroreceptor firing and tachycardia ✓
- C. Decreased sympathetic output
- D. Peripheral vasodilation
Why: Pressure falls on standing, so baroreceptors fire less; the brainstem responds with more sympathetic output, raising heart rate and vascular tone.
You ask Cue: Why does my heart rate go up when I stand?
Standing pools blood in the legs, so venous return and blood pressure drop briefly. The carotid baroreceptors fire less, which increases sympathetic output and raises heart rate to restore pressure. p.12
Example generated from a short sample excerpt. In recalled.fyi, every question and answer comes from the material you upload.
What to turn into questions
- "What happens if…" changes to one variable, and the knock-on effects
- Curves and loops: what shifts them and in which direction
- Reflexes and feedback loops, step by step
- Comparisons between similar mechanisms
How recalled.fyi helps
- Questions built on mechanisms and predictions, not just definitions
- Explanations that walk through the reasoning, including why other options fail
- Ask Cue to explain a step you do not follow, with the page it came from
- Spaced reviews so the logic is still there before the exam

Can it help with graphs and curves?
If the curve is in your slides, recalled.fyi can describe it and ask what shifts it. Cue can also explain a curve from your notes in plain language.
Is it only for medicine?
It is built for medical and health-science students, but it works with any dense course material.
