Plural of bloodstream; multiple circulating systems of blood in different organisms or instances.
Plural of bloodstream, itself a compound of blood and stream (from Old English streame), referring to the flow of blood through veins and arteries.
The term 'bloodstream' revolutionized medicine when people understood circulation—before Harvey's discoveries in the 1600s, they didn't realize blood actually moved through the body in streams, which changed everything about medical treatment.
