How do pain relievers work?increase production of white blood cells
increase body temperature
block messages within the nervous system
block hormone production

Answers

Answer 1
Answer:

Answer:

The correct answer is option C, block messages within the nervous system

Explanation:

Whenever our body gets injured, the damaged cells in it releases a chemical known as “prostaglandin” which sends pain signals through the nerves to the brain. Now when a pain reliever is injected in the body, it stops the production of prostaglandin. As the chemical production stops, no pain messages are send to the brain and thus the pain goes away

Answer 2
Answer: I believe the answer is is that it blocks messages within the nervous system, because pain is perceived in the brain through messages sent from the nervous system.
