Pulmonary Embolism

A clot breaks loose and, with it, HELL, it formed in silence, grew in weeks, the patient lives and feels quite well the thrombus, reddish black, it seeks a place where oxygen abounds to charge its body, to expand, it passes through the heart and rounds the pulmonary passage and..... gets swept into the lungs at once where tunnels narrow soon to trap the thrombus and its little sons that followed through the slippery gap. Name change occurs, an embolus, it paralyses action soon, and like a nasty octopus creates a bloodless, dead lagoon. More thrombi follow, it's the rule, in time the mother of them all arrives in absolute self-rule all blood flow to the lungs will stall. It plugs the duct, which triggers then a valiant response to squeeze and overcome by force of ten the obstacle, restoring ease. It's not to be, the plug sits tight blue lips and cyanotic nails show signs of this, its final fight the bastard wins, the heart soon fails.
