the smallest cell fragment in your blood, plugging leaks like a microscopic tradesman with no contract.
means A platelet is a tiny disc-shaped cell fragment in your blood that clumps together at the site of an injury to form clots and stop bleeding.
from From 'plate' plus the diminutive '-let,' so literally 'a little plate' — the term arose in late-19th-century microscopy when researchers peering down lenses saw these things as small flattened discs and named them accordingly. 'Plate' itself traces back through Old French 'plate' to the Greek 'platys,' meaning broad or flat, a root that also gives us 'plateau' and 'platypus.'
