A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. … The English word “tissue” derives from the French word “tissue”, meaning that something that is “woven”, from the past participle of the verb tisser, “to weave”.
Apart to say that in the 16th and 17th centuries, tissue was a finely woven fabric and very expensive.
Not a Kleenex. Or a disposable mask.
BTW : How did THE PLAGUE morph from rats to breathing?
