Question

The plasma is a viscous, light red liquid, i.e. almost clear in the fasting stage.

(a) True

(b) False

This question was addressed to me by my school teacher while I was bunking the class.

Query is from Respiratory Gas Analysers in section Pulmonary Function Analysers of Biomedical Instrumentation

Answer 1

Right option is (b) False

Easy explanation: False, because the plasma is obtained by centrifuging a blood sample. During centrifugation, the heavy blood cells get packed at the bottom of the centrifuge tube and the plasma can thus be separated. The plasma is a viscous, light yellow liquid, i.e. almost clear in the fasting stage.
