Zoology - Breathing and Exchange of Gases

Practise 16 AIIMS previous year questions on Breathing and Exchange of Gases, compiled from papers spanning 2001 to 2019. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AIIMS tests.

Breathing and Exchange of Gases has been asked in 11 of the 19 years of AIIMS papers analysed (2001–2019), with 16 questions in all. 44% of them were easy, 31% moderate and 25% tough. Most of its questions came from 2018, with 2 questions that year. In the last three years (2017–2019) it had 3 questions across 5 papers, about 0.6 per paper.

The chapter's 2 topics are not weighted equally: Human Respiratory System (14 questions, 88%) and Respiratory Organs (2 questions, 13%) have been asked the most. Human Respiratory System has produced the most tough questions (4).
