Human Physiology — NDA Biology 52 PYQs · 9 subtopics Human Physiology is the largest chapter in NDA Biology — 52 PYQs across 2017–2026, almost all EASY or MODERATE, and almost all pure named-fact recall. The trick is not derivation; it is knowing the right table cold. The chapter teaches in nine movements, building from the body's raw materials up to whole organ systems: (1) Body tissues — the four tissue types and the connective-tissue family (blood, cartilage, tendon, ligament) that every later system is built from; (2) Digestion and enzymes — the enzyme-substrate-source-pH table and the gland chain that processes food; (3) Nutrition — the vitamin-deficiency table (the single highest-yield table in the chapter), balanced diet, and minerals; (4) Circulation — heart chambers and valves, arteries vs veins, blood, lymph and clotting; (5) Respiration — the airway, gas exchange in the alveoli, and lung volumes; (6) Excretion and reproduction — the nephron and spermatogenesis; (7) Nervous system and sense organs — the nerve impulse, the reflex arc and brain, and the eye; (8) Endocrine system — the hormone-gland-function table; (9) Immune system — which cells make antibodies. 23 concepts, every PYQ tagged. Most concepts are reference tables: memorise the table, win the marks.
