Key Sub-Topics & What's Tested
Digestion & Absorption
Alimentary canal anatomy, digestive enzymes and their substrates, absorption mechanisms, disorders (PEM, jaundice, indigestion).
Breathing & Exchange of Gases
Respiratory system structure, mechanism of breathing, oxygen/CO₂ transport, oxygen dissociation curve, respiratory disorders (asthma, emphysema).
Body Fluids & Circulation
Blood composition (RBC, WBC, platelets), blood groups (ABO, Rh), double circulation, cardiac cycle, ECG components, coronary artery disease.
Excretory Products & Elimination
Urea formation, nephron structure and function, glomerular filtration, counter-current mechanism, dialysis, renal disorders.
Locomotion & Movement
Types of movement, skeletal muscle anatomy, sliding filament theory, types of joints, disorders (arthritis, osteoporosis, myasthenia gravis).
Neural Control & Coordination
Neuron structure, nerve impulse propagation, synaptic transmission, reflex arc, human CNS structure (cerebrum, cerebellum, brain stem, spinal cord).
Chemical Coordination & Integration
Endocrine glands (pituitary, thyroid, pancreas, adrenal, gonads), hormones and their actions, mechanism of hormone action, hormonal disorders.
Question Type Distribution
| Question Type | Share (approx) | Example Pattern |
|---|---|---|
| System Anatomy / Structure | 25% | Identify structures in diagram of nephron, alimentary canal, heart, neuron, or skeletal muscle. |
| Enzyme/Hormone Function | 25% | Which enzyme digests proteins in stomach? Which hormone regulates blood glucose? |
| Disorder-Cause Matching | 15% | Match disorder with cause: Addison's disease, diabetes insipidus, myasthenia gravis, Alzheimer's. |
| Mechanism Questions | 15% | How does sliding filament theory explain muscle contraction? Steps in oxygen dissociation. |
| Physiological Values | 10% | Normal glomerular filtration rate? Normal systolic/diastolic blood pressure? |
| Cycle Sequencing | 10% | Arrange events of cardiac cycle in correct sequence: atrial systole, ventricular systole, ventricular diastole. |
How to Solve Human Physiology (7-Chapter Block) PYQs
- 1Tackle chapters in priority order. Neural + Chemical Coordination + Body Fluids are the most-tested trio. Digestion, Breathing, Excretion next. Locomotion last.
- 2Draw NCERT diagrams from memory. Nephron, heart cross-section, neuron, alimentary canal, skeletal muscle, endocrine system. NTA asks identification questions directly from these.
- 3Enzyme-hormone-disorder tables. Build tables per system. NEET loves matching questions — enzyme to substrate, hormone to target organ, disorder to cause.
- 4Physiological normal values. Blood pressure (120/80), blood glucose (80-120 mg/dL), body temp (37°C), GFR (~125 mL/min). Know the normal ranges.
- 5Cross-connect across chapters. Body Fluids connects to Breathing (gas transport). Neural connects to Locomotion (motor signals). Chemical connects to all (hormones affect every system).
Common Mistakes That Cost Marks
- Confusing insulin and glucagon actions. Insulin lowers blood glucose (anabolic). Glucagon raises blood glucose (catabolic). Both from pancreas but opposite effects.
- Wrong direction of nerve impulse. Dendrites → cell body → axon. Axon carries impulse AWAY from cell body. Never reverse this.
- Applying counter-current to Breathing. Counter-current mechanism is for urine concentration in nephron. Breathing uses pressure gradients, not counter-current.
- Calling RBC "white blood cells". RBC = erythrocytes (red). WBC = leucocytes (white). RBC has no nucleus in mammals (except mature) — a distinguishing feature.
- Treating nodal tissue as nerve tissue. SA node is modified cardiac muscle, not nervous tissue. It initiates cardiac rhythm but is muscular in origin.

Frequently asked questions
How many Human Physiology PYQs should I solve?
Target 150+ Human Physiology PYQs across all 7 chapters. Given its ~18% combined weightage on trend, this is among the highest-return study blocks in NEET Biology.
Is NCERT Class 11 Unit 5 enough?
Yes — 7 chapters (Ch 16 to 22) in NCERT Class 11 cover this block. Read each 3+ times with PYQ reinforcement. Coaching summaries don't match NTA phrasing well.
Which Human Physiology chapter is most-tested?
Neural Control and Chemical Coordination — ~4-5 PYQs per chapter per 10-year window combined. Body Fluids and Excretion are close seconds.
Do I need to memorise every hormone?
Major hormones from each gland: yes. Pituitary (all tropic hormones), thyroid (T₃, T₄), pancreas (insulin, glucagon), adrenal (cortisol, aldosterone), gonads (testosterone, estrogen, progesterone). NCERT covers these.
Are diagram-based PYQs common?
Very — ~25% of Human Physiology PYQs ask identification of structures in NCERT diagrams. Drawing from memory is the best preparation.
Does Human Physiology connect with Human Reproduction?
Yes — Chemical Coordination overlaps with Reproduction via reproductive hormones (FSH, LH, estrogen, progesterone, testosterone). Study them together for reinforcement.
