Which term best matches the following definition: Blood coagulation disorder in which the blood fails to clot normally?

• A. Hemophilia
• B. Diabetes Mellitus
• C. Emphysema
• D. Endocarditis

Answer: (A)

Blood clotting involves a cascade of proteins called clotting factors. When one or more factors are missing or defective, the blood cannot clot normally. Hemophilia is a genetic disorder in which factors needed for clot formation, typically factor VIII or IX, are deficient or not working. This causes clots to form slowly or not at all, leading to prolonged bleeding, easy bruising, and potential joint bleeds. The other options describe conditions unrelated to clotting: Diabetes mellitus affects insulin and blood sugar; emphysema is a lung disease; endocarditis is an infection of the heart valves. So the term that best fits the definition is Hemophilia.
