Human Physiology NCERT MCQs for NEET — All Chapters Practice

Human Physiology spans 6 chapters in NCERT Class 11 Biology and contributes 14–16 questions to NEET every year. It's the most content-heavy Biology section but also highly predictable — NTA consistently tests the same diagrams, numerical values, and process steps from NCERT.

Chapter-Wise Breakdown: Human Physiology for NEET

Digestion and Absorption (Chapter 16): Alimentary canal structure, digestive glands (salivary, gastric, pancreatic, intestinal), enzymes and their actions, absorption mechanisms (simple diffusion, facilitated transport, active transport), disorders. Breathing and Exchange of Gases (Chapter 17): Respiratory organs, mechanism of breathing, lung volumes (TV 500ml, IRV 2500ml, ERV 1000ml, RV 1100ml), gas transport (oxyhaemoglobin, carbamino-haemoglobin), respiratory disorders. Body Fluids and Circulation (Chapter 18): Blood composition, blood groups (ABO, Rh), cardiac cycle (cardiac output = 5L/min), double circulation, ECG, disorders. Excretory Products (Chapter 19): Nephron structure, ultrafiltration, selective reabsorption, tubular secretion, counter-current mechanism, GFR 125ml/min, ADH, disorders. Neural Control (Chapter 21): Neuron structure, nerve impulse (resting and action potential, -70mV), synapse, CNS and PNS, reflex arc, sensory organs. Locomotion and Movement (Chapter 20): Muscle types, sarcomere structure, sliding filament theory, joints, skeletal system, disorders.

Critical NCERT Values You Must Memorise

NEET frequently tests specific numerical values from NCERT: • Tidal Volume: 500 mL • Vital Capacity: ~4500 mL • Total Lung Capacity: ~6000 mL • Cardiac Output: 5 L/min (Heart Rate 70/min × Stroke Volume 70mL) • GFR: 125 mL/min (180 L/day filtered) • Resting Membrane Potential: -70 mV • Normal Blood Pressure: 120/80 mmHg
