integrated respiratory, circulatory, excretory, neural, endocrine and movement physiology.

Original practice preview

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

Example 1 · difficulty 2/5

Of the total carbon dioxide carried by human blood, the largest share is transported:

A. physically dissolved in the plasma
B. bound to the globin portion of haemoglobin as carbaminohaemoglobin
C. as stable carbonic acid circulating in the plasma
D. as bicarbonate ions, mostly delivered to plasma after forming inside RBCs

Example 2 · difficulty 3/5

In metabolically active tissues, which set of conditions favours dissociation of oxygen from oxyhaemoglobin (rightward shift of the O₂ dissociation curve)?

A. low pCO₂, low H⁺ concentration and low temperature
B. high pCO₂, high H⁺ concentration and high temperature
C. high pO₂, low pCO₂ and high temperature
D. low pO₂, low H⁺ concentration and low temperature

Example 3 · difficulty 3/5

In a healthy adult male, tidal volume = 500 mL, inspiratory reserve volume = 2500 mL, expiratory reserve volume = 1000 mL and residual volume = 1200 mL. His functional residual capacity (FRC) is closest to:

A. 1500 mL
B. 4000 mL
C. 2200 mL
D. 5200 mL

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 2019 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 2019 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.
