Human Physiology is the most heavily-tested chapter in NEET Biology. Every year you can expect 10–12 questions across the major systems: digestion (enzyme action, absorption), breathing (transport of gases, lung volumes), circulation (cardiac cycle, ECG, BP regulation), excretion (nephron, glomerular filtration, hormones), nervous system (neuron, reflex arcs, brain), and endocrine (hormone-gland-target table).
NCERT chapters to cover
- 📘Class 11 Ch 16: Digestion and Absorption
- 📘Class 11 Ch 17: Breathing and Exchange of Gases
- 📘Class 11 Ch 18: Body Fluids and Circulation
- 📘Class 11 Ch 19: Excretory Products and their Elimination
- 📘Class 11 Ch 20: Locomotion and Movement
- 📘Class 11 Ch 21: Neural Control and Coordination
- 📘Class 11 Ch 22: Chemical Coordination and Integration
Exam tips
- 1Make a hormone table: gland, hormone, target, function, deficiency, excess. Memorize cold.
- 2Cardiac cycle: P-wave (atrial depolarization), QRS (ventricular depolarization), T (ventricular repolarization).
- 3Nephron: glomerular filtration (~125 mL/min), then selective reabsorption in PCT, loop of Henle, DCT, collecting duct.
