Formación de coágulos sanguíneos:

Formación de coágulos sanguíneos

La coagulación sanguínea normalmente se presenta cuando hay un daño a un vaso sanguíneo. Las plaquetas comienzan a adherirse inmediatamente a los bordes del vaso donde se ha producido el corte y liberan químicos para atraer aún más plaquetas. De esta manera, se forma un tapón plaquetario y el sangrado externo se detiene.

Acto seguido, pequeñas moléculas denominadas factores de coagulación, hacen que las hebras de materiales de transmisión hemática, denominados fibrinas, se unan y sellen el interior de la herida. Finalmente, el vaso sanguíneo lesionado sana y se disuelve el coágulo luego de unos pocos días.
