Answer 1

The nsaids are drugs that reduces inflammation, pain and fever. The enzymes cyclooxygenases are those enzyme that produce prostaglandins.

COX is of two types- COX1 and COX2

COX 1 produces prostaglandins that activate platelets and protect the stomach and inteatinal lining.

NSAIDS block COX enzymes and that will inhibit production of prostaglandins which will reduce pain, fever, inflammation in turn those prostaglandins that protect stomach and promote blood clotting also will be reduced..

So the blood clotting prostaglandins will be reduced that will increase the risk of bleeding
