Zoology - Body Fluids and Circulation

Practise 95 NEET previous year questions on Body Fluids and Circulation, compiled from papers spanning 2002 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty NEET tests.

Body Fluids and Circulation has been asked in 25 of the 39 years of NEET papers analysed (1988–2026), with 95 questions in all. 56% of them were easy, 43% moderate and 1% tough. Most of its questions came from 2009, with 9 questions that year. In the last three years (2024–2026) it had 13 questions across 13 papers, about 1 per paper.

The chapter's 12 topics are not weighted equally: Blood (32 questions, 34%), Blood Group (14 questions, 15%), and Human Circulatory System (11 questions, 12%) have been asked the most. Over the last five years the most frequent topics have been Blood Group (4), Blood (4), and Electrocardiograph (3). Blood Group has produced the most tough questions (1).
