Concept:The lymphatic system manages fluid homeostasis, lipid absorption, and immune defense, but has no role in respiratory gas transport.
Formula:None
Solution:- If the lymphatic system disappeared, leaked plasma could not return to the veins, destroying blood volume and blood pressure.
- Without lymph nodes, the adaptive defense mechanism would collapse.
- However, the oxygen-carrying capacity of blood is determined entirely by the mass of Red Blood Cells and hemoglobin molecules locked safely within the cardiovascular system. Since RBCs do not leave the blood vessels to enter lymph, their oxygen-carrying capacity remains mechanically unaffected.
Why other options are incorrect:- Blood composition would alter as proteins and fluid leak into tissues without returning.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
