Physiology for NEET PG

Physiology rewards understanding mechanisms: why a value rises or falls when a variable changes. Graphs, flow charts and 'what happens if' reasoning matter more than recalling definitions.

What Physiology covers

  • General physiology
  • Blood and immunity
  • Nerve and muscle
  • Cardiovascular system
  • Respiratory system
  • Renal and acid–base
  • Gastrointestinal
  • Endocrinology
  • Reproduction
  • Neurophysiology and special senses

How to study it

  1. 1

    For each system, sketch the key graph (pressure–volume loop, oxygen dissociation curve, nephron handling) and explain it aloud.

  2. 2

    Practise 'if X changes, what happens to Y' questions, because that is how application is tested.

  3. 3

    Keep a one-page sheet of normal values and the direction in which each shifts.

Where students slip

  • Memorising values without knowing what moves them.
  • Confusing what is measured (clearance) with what it estimates (GFR or plasma flow).

Where the Physiology practice questions concentrate

Our 951 worked Physiology questions fall into these areas, largest first. This shows what our practice set emphasises. It is not a prediction of the exam's weightage.

Four quick-revision cards

  • Which substance's clearance equals GFR?

    Inulin: freely filtered, not reabsorbed or secreted.

  • Which phase has all four valves closed while pressure rises?

    Isovolumetric contraction.

  • Four things that shift the O₂–Hb curve to the right?

    Raised 2,3-BPG, CO₂, H⁺ (low pH) and temperature.

  • Where is conduction slowest in the heart and why?

    AV node: the delay lets the atria empty before the ventricles contract.

Common questions

How do I stop forgetting physiology values?

Use spaced flashcards for normal values and revise the mechanism behind each, so the number has something to hang on.

Are graphs important?

Yes. Many questions are graph-based, so learn to read axes and predict shifts.
