Question

At the site of tissue injury, the activated platelet releases ADP and activates surrounding platelets to form platelet plug, but this process will not continue to activate whole platelets in the body to form a massive ball of platelets because

• A. The adjacent normal endothelial cells physiologically release ‘NO’ which is a platelet inhibitor
• B. There will be plasminogen activators in the plasma
• C. There will be plasminogen activator inhibitors in plasma
• D. There will be a tissue plasminogen activator (tPA) which inhibits the platelets

Answer 1

The Correct Option is A

The correct option is (A): The adjacent normal endothelial cells physiologically release ‘NO’ which is a platelet inhibitor
