Frequently Asked Questions

Q1. How many chapters in human physiology for NEET?

Answer. Human Physiology comprises of 7 chapters in NEET - 2 chapters in Class 11 and 5 chapters in class 12. The chapters in Class 11 are : Digestion and Absorption which discusses the digestive system, enzymes and absorption of nutrients; and Breathing and Exchange of Gases which refers to the respiratory system and the exchange of gases in the lungs. There are 5 chapters in Class 12- Body Fluids and Circulation which covers the circulatory system and blood flow; Excretory Products and their Elimination which covers the kidneys and urine formation; Locomotion and Movement which discusses the muscular system and muscle contraction; Neural Control and Coordination which refers to the nervous system and reflex arcs; and Chemical Coordination and Integration covers the endocrine system and the hormonal system. These chapters are very important for understanding the function of various systems in the human body and as such are important for NEET.

Q2. Which chapters are removed from NEET 2025 biology?

Answer. For NEET UG 2025, selected chapters from the Biology syllabus have been removed to concentrate on the core topics. Chapters in Class 11, for example, Diversity in Living Organisms, included a vast amount of classification and role of different biological tools, etc., is excluded. The chapter in Class 11 on Structural Organization in Animals & Plants was also removed; this was the chapter that included a detailed review of anatomy and physiology of various systems in the organism. Plant Physiology was reduced to mainly studying long-distance transport (like xylem, phloem) and Mineral Nutrition. The chapter on Digestion and Absorption is completely removed. Items from Neural Control and Coordination and Plant Growth and Development were also removed.

Moving onto Class 12, the chapters: Reproduction in Organisms and Environmental Issues were removed. Most of the chapter on Strategies for Enhancement in Food Production, and the topics related to Ecosystems, were removed. This makes the syllabus very streamlined, removing some of the less essential materials from prior exams but still retains the core concepts of the material for better learning and more solid preparation.
