Human Physiology important topics for NEET include digestion, respiration, circulation, excretion, and neural control. Human Physiology is a pivotal section in the NEET Biology syllabus, accounting for about 16% of the exam questions. Mastering this unit can significantly enhance your overall score. While every chapter is important, some areas—such as Body Fluids and Circulation, Neural Control and Coordination, and Chemical Coordination and Integration—tend to carry more weight. To help you focus on high-yield topics, we’ve compiled a list of the most frequently tested concepts in Human Physiology for NEET. Digestion and Absorption This chapter lays the groundwork for understanding Human Physiology, with 1-3 questions typically appearing in the exam each year. Key areas to focus on include: Alimentary Canal – Structure and function of the digestive tract Digestive Glands – Salivary glands, liver, pancreas, and their roles Digestive Enzymes – Their function in breaking down food Nutrient Absorption – How and where different nutrients are absorbed Common Digestive Disorders – Jaundice, diarrhea, and vomiting Breathing and Exchange of Gases This chapter delves into the mechanics of human respiration, with around 1-2 questions appearing each year. Essential topics include: Respiratory Mechanism – How inspiration and expiration occur Respiratory Volumes & Capacities – Tidal volume, vital capacity, etc. Gas Exchange – Diffusion of oxygen and carbon dioxide Oxygen Dissociation Curve – Bohr’s and Haldane effects Regulation of Breathing – Neural and chemical control mechanisms Respiratory Disorders – Asthma, emphysema, and related conditions Body Fluids and Circulation This chapter, which covers blood, lymph, and the circulatory system, contributes approximately 2-3 questions in NEET. Important concepts include: Blood Composition – Functions of RBCs, WBCs, and platelets Blood Groups – ABO system and Rh factor significance Heart Structure & Function – Chambers, valves, and conduction system Cardiac Cycle – Phases and associated heart sounds ECG Interpretation – Understanding P waves, QRS complexes, and T waves Circulatory Disorders – Hypertension, atherosclerosis, and related conditions Excretory Products and Their Elimination On average, this chapter yields 1-2 questions in NEET. Key focus areas include: Kidney Structure & Function – Nephrons and renal corpuscle Glomerular Filtration Rate (GFR) – Factors affecting GFR Tubular Function – Reabsorption and secretion processes Counter Current Mechanism – Role of Henle’s loop and vasa recta Regulation of Kidney Function – Influence of ADH and aldosterone Excretory Disorders – Conditions like kidney stones and uremia Locomotion and Movement At least one NEET question is drawn from this chapter every year. Topics to concentrate on include: Types of Muscles – Skeletal, smooth, and cardiac Muscle Structure – Sarcomere and contractile proteins Muscle Contraction – Sliding filament theory explained Skeletal System – Overview of skull bones, vertebral column, and rib cage Joints and Disorders – Types of joints and common conditions like arthritis Neural Control and Coordination With 1-3 questions in the NEET exam, this is a high-yield chapter. Key concepts include: Human Neural System – Central, peripheral, and autonomic nervous systems Neuron Structure & Function – Different types and their properties Nerve Impulse Transmission – Action potential and signal conduction Brain Anatomy & Function – Role of cerebrum, cerebellum, and medulla Eye & Ear Mechanisms – Structure and functioning of photoreceptors and the auditory system Chemical Coordination and Integration As the most significant chapter in Human Physiology, this section extensively covers the endocrine system, with 2-4 questions typically appearing in NEET. Essential topics include: Pituitary Gland – Hormones and their functions Pineal Gland – Role of melatonin in biological rhythms Thyroid Gland – Functions of T3, T4, and calcitonin Adrenal Gland – Hormones like cortisol, adrenaline, and noradrenaline Pancreatic Hormones – Insulin and glucagon regulation Hormone Mechanisms – Pathways like cAMP and IP3 signaling Smart Preparation Strategies for NEET and Human Physiology Important Topics for NEET also Focus on conceptual understanding rather than memorization.
