TY - JOUR T1 - BLeeding disorders AU - Goodman DM, Burke AE, Livingston EH Y1 - 2012/10/10 N1 - 10.1001/jama.2012.4089 JO - JAMA SP - 1492 EP - 1492 VL - 308 IS - 14 N2 - When tissues are injured, blood cell fragments called platelets gather at the wound, providing a foundation for coagulation (clotting). Platelets are bound together by a glue-like protein named von Willebrand factor. Once the initial platelet plug is built, clotting factors gather at the injury site to seal the wound, stop bleeding, and begin the healing process. The clotting factors work in a carefully timed sequence, resulting in a sturdy clot and healed wound. SN - 0098-7484 M3 - doi: 10.1001/jama.2012.4089 UR - http://dx.doi.org/10.1001/jama.2012.4089 ER -
