Class 11 Biology — Breathing and Exchange of Gases Important Questions with Answers (Long answers)
Class 11 Biology is diversity, cell ultrastructure, biomolecules, cell cycle, plant physiology and a long human-physiology block. The rationalized book is slimmer than older reprints; this hub follows surviving units so you do not revise a deleted kingdom chapter as if it were 2026. Diagram-based MCQs (neuron, nephron, chloroplast) sit with short “give reason” items. Hidden answers, twenty a page.
Breathing and Exchange of Gases — श्वसन और गैसों का विनिमय
Human respiratory tract, volumes (TV, IRV, ERV, VC), transport of O₂/CO₂, and a little regulation. Hb–O₂ dissociation shifts with CO₂, H⁺, temperature. Asthma versus emphysema as the book names them. Write the volume definition before the number. You are on Breathing and Exchange of Gases (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
