Blood Composition, Hemostasis and Blood Groups
- Previous year questions on Blood Composition, Hemostasis and Blood Groups for NEET PG (National Eligibility cum Entrance Test - Postgraduate), from the Physiology section of the exam.
- Most questions here come from previous-year papers of Indian postgraduate medical entrance and licensing exams; where a paper and year are recorded the question carries them. The image-based questions are original vignettes written around an openly licensed figure, and were never asked in any exam.
- 114 live questions in Blood Composition, Hemostasis and Blood Groups.
- 4 of 114 questions carry a verified exam year: 2018, 2019.
- Physiology is worth about 17 of 300 questions on the exam. See every subject’s weightage.
