Hemophilia, also known as haemophilia, is a group of inherited blood disorders in which the blood does not clot properly. Bleeding disorders are due to defects in the blood vessels, the coagulation mechanism, or the blood platelets. An affected individual may bleed spontaneously or for longer than a healthy person after injury or surgery.
Hemophilia parted as three types:
* Hemophilia A
* Hemophilia B
* Hemophilia C
