Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 1/5

In a differential leucocyte count of a normal healthy adult, the cell type appearing in the highest percentage is:

A. Lymphocytes, the key cells of specific immunity
B. Monocytes, which transform into macrophages
C. Neutrophils, forming about 60-65 percent of total leucocytes
D. Eosinophils, which increase during allergic reactions

Example 2 · difficulty 3/5

One complete cardiac cycle in a resting human lasts about 0.8 seconds. Within this cycle, the ventricles remain contracted (in systole) for:

A. 0.3 seconds
B. 0.1 seconds
C. 0.4 seconds
D. 0.7 seconds

Example 3 · difficulty 2/5

Blood collected in a vial containing sodium oxalate remains uncoagulated even though all its plasma proteins are intact. The most appropriate explanation is:

A. Oxalate directly denatures fibrinogen molecules
B. Oxalate disintegrates the platelets forming the plug
C. Oxalate triggers release of a natural anticoagulant protein
D. Oxalate removes calcium ions, which are essential for converting prothrombin to thrombin

The evidence-first practice loop

1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
2. Attempt closed-bookExpose the concept or execution gap before rereading.
3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2017 Biology Human Physiology PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2017 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
