Answer:

Leeches

Explanation:

They aren't as commonly used as they may have been in places such as ancient Rome or Egypt. But leeches are still used today, even in procedures such as microsurgery. Leeches secrete polypeptides and enzymes that work to prevent blood clots. So they can be useful when it's crucially necessary to avoid bloodclots during a procedure.
