Zoology - Body Fluids and Circulation

Practise 53 AIIMS previous year questions on Body Fluids and Circulation, compiled from papers spanning 2002 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.

Body Fluids and Circulation has been asked in 18 of the 19 years of AIIMS papers analysed (2001–2019), with 53 questions in all. 47% of them were easy, 32% moderate and 21% tough. Most of its questions came from 2014, with 5 questions that year. In the last three years (2017–2019) it had 9 questions across 5 papers, about 1.8 per paper.

The chapter's 8 topics are not weighted equally: Blood Group (11 questions, 21%), Blood (11 questions, 21%), and Human Circulatory System (10 questions, 19%) have been asked the most. Cardiac Cycle has produced the most tough questions (4).
