The protein scab you build the instant you bleed, stitching wounds shut with molecular thread.
means The insoluble, thread-forming protein made when the blood protein fibrinogen is cleaved by thrombin, weaving into a mesh that clots blood.
from Straightforward Latin lineage: 'fibrin' comes from fibra, meaning 'fiber' or 'thread,' with the chemical suffix -in slapped on as was common for naming isolated biological substances in 19th-century chemistry. Scientists studying clotted blood saw actual fibrous strands under early microscopes and simply named the stuff for what it looked like — thread. No hidden myth here, just chemists calling fiber 'fiber.'
