what is febrino license a process that promotes further cloud formation B process that promotes clot destruction see process controlled solely by plasmin or de-process the response to decreased levels of pdgf Which of the following is considered an intrinsic anemia? a. Thallasemia minor b. Iron-deficiency anemia c. DIC d. Thromobocytopenia
The correct answer and explanation is:
The correct answer for the first question about febrino license is B. process that promotes clot destruction.
Explanation:
Fibrinolysis is a process in which the body breaks down blood clots. It helps to remove clots once they have fulfilled their role in stopping bleeding. The process is regulated by enzymes such as plasmin, which break down fibrin, the protein that forms the scaffold of the clot. This allows for the re-establishment of normal blood flow in the vessel after the injury has healed. Plasminogen is the precursor to plasmin, and it is activated to plasmin in response to signals such as tissue plasminogen activator (tPA). Once activated, plasmin breaks down fibrin into smaller products, leading to clot resolution.
For the second question regarding intrinsic anemia, the correct answer is A. Thalassemia minor.
Explanation:
Anemia can be categorized into intrinsic and extrinsic types. Intrinsic anemia refers to a condition where the red blood cells themselves are defective, whereas extrinsic anemia arises from external factors like blood loss or destruction. Thalassemia minor is an inherited blood disorder where the body makes an abnormal form of hemoglobin, resulting in a mild form of anemia. It affects the production of hemoglobin, which can lead to the premature destruction of red blood cells, though individuals with thalassemia minor usually have mild or no symptoms.
- Iron-deficiency anemia (B) is an extrinsic anemia because it results from inadequate iron intake or absorption, not an intrinsic issue with the red blood cells themselves.
- DIC (Disseminated Intravascular Coagulation) (C) is a condition involving widespread clotting and clot destruction, but it is not classified as an anemia.
- Thrombocytopenia (D) refers to a low platelet count, not an anemia. It is a condition that affects the blood’s ability to clot but doesn’t directly involve red blood cells.
Thalassemia minor is considered intrinsic because it involves an issue with the hemoglobin molecule inside the red blood cells, leading to premature cell destruction.
