Substance formed by basophils:
Correct answer: D. Both A and B
- A. Heparin
- B. Histamine
- C. Antibody
- D. Both A and B
Explanation
The correct answer is both A and B. Basophils are a type of white blood cell that are involved in the immune system. They release histamine and heparin, which are both important substances in the body's response to allergic reactions and inflammation. Heparin is an anticoagulant that helps to prevent blood clots. It is also a potent anti-inflammatory agent. Histamine is a chemical that causes inflammation and allergic reactions. It is also involved in the regulation of blood pressure and the digestive system. Basophils also release other substances, such as cytokines and leukotrienes, but these are not as important as histamine and heparin.
