 * Hemophilia**

Hemophilia is a rare, inherited blood disorder. When someone has Hemophilia, their blood does not clot. This means that they can bleed for days, even after receiving a very small cut or wound. Also, Hemophilia can cause internal bleeding, which normally occurs in the joints, such as the knees, elbows, and ankles. There are two types of Hemophilia. People with Hemophilia A are missing Clotting Factor VIII. People with Hemophilia B are missing Clotting Factor IX. Since they are missing either clotting factors VIII or IX, they bleed for long periods of time. The blood of people with Hemophilia does clot, but it forms a weak clot, which is easily dislodged.
