How toppers play this section

Physiology is worth more than its ten questions, because the reasoning it teaches is what makes Medicine answerable. Cardiovascular, renal and nerve-muscle physiology dominate both the direct questions and the indirect ones. Work in curves and pressures rather than isolated values: knowing what shifts a curve and why explains the acid-base question, the shock question and the ventilation question in one move.

Chapters

Built to the NEET PG blueprint — notes, shortcuts, solved PYQ-style examples and practice in every chapter.

1Cardiovascular PhysiologyCardiovascular physiology is the subject where a waveform is a diagnosis. This chapter builds the cardiac action potential, the cardiac cycle with its pressure-volume loop and jugular waveform, the determinants of cardiac output, and the haemodynamics of shock — so that a described murmur, wave or set of pressures can be reasoned to a cause rather than matched to a memory.⏱ 21 min read

2Endocrine PhysiologyEndocrinology is a subject of feedback loops, and almost every question is answered by asking which limb of a loop has failed. This chapter builds the pituitary axes, thyroid synthesis and autoregulation, adrenal steroid pathways and calcium and glucose control around that logic, so a set of hormone levels can be reasoned to a diagnosis.⏱ 21 min read

3GI PhysiologyGastrointestinal physiology is organised around secretion, motility and absorption, and each is governed by a small set of hormones and reflexes. This chapter builds acid secretion, pancreatic and biliary control, motility disorders and the site-specific absorption map, so a described deficiency or diarrhoea can be traced back to the segment that failed.⏱ 21 min read

4Nerve-Muscle Physiology & CNSNerve and muscle physiology is tested as a chain — a signal is generated, transmitted across a synapse, converted into calcium release, and turned into force. This chapter follows that chain from membrane potential to cross-bridge, then adds the reflex and sleep physiology that the CNS questions rest on, so a described weakness can be traced to the step that failed.⏱ 21 min read

5Renal PhysiologyRenal physiology is organised segment by segment, and almost every question is answered by identifying which part of the nephron is involved. This chapter builds filtration and its autoregulation, the transporters of each tubular segment with the diuretics and genetic syndromes that target them, the countercurrent mechanism, and acid-base handling including the renal tubular acidoses.⏱ 21 min read

6Respiratory PhysiologyRespiratory physiology is dominated by two questions — is this lung stiff or floppy, and is gas reaching blood that can carry it away. This chapter builds volumes and compliance, ventilation-perfusion matching, oxygen and carbon dioxide transport, and the control of breathing, so that a blood gas can be reasoned to a mechanism rather than matched to a pattern.⏱ 21 min read
