Parto vaginal

Cuándo el cuello uterino se dilata hasta diez centímetros, la fase de pujado y alumbramiento del parto comienza. Durante esta fase, el bebé comienza su viaje a través del canal del parto. A medida que la cabeza del bebé rota, puede deformarse a medida que va más lento al salir por esa abertura tan angosta. Los huesos del cráneo del bebé tienen brechas llamadas fontanelas que permiten que su cabeza se alargue y quepa por el canal del parto.

A medida que la cabeza del bebé es alumbrada, girará naturalmente hacia un lado. La cabeza y los hombros del bebé son soportados por el resto del cuerpo del bebé, que generalmente sale bastante rápido.
