Decongestants tend to unblock your nose and chest, it depends or how clogged you feel. An antihistamine is supposed to block or slow the release of histamine, which produces the excess mucus. If your nose is running and you are sneezing, you may can get by with just an antihistamine. Now if you are like me and woke up sneezing your head off, but your lungs and nasal passages are still clogged, you need to take the decongestant too.
During a fight or flight response, your body provides you with the energy, reflexes, and strength you may need to respond to the stressor. An example of this is would be if you were in the path of a fast moving vehicle and you suddenly feel a burst of energy that allows you to get out of the way of the car.
Hope this helps :)

Answer:
The correct answer will be- to provide smooth surface at the ends of synovial joint.
Explanation:
Articular cartilage is the white smooth tissue present at the end of the bones which covers the bones at the joints. The articular cartilage is devoid of the nerves, blood vessels and lymphatics but is exposed to the biochemical environment.
The cartilage at the joint helps in the movement of the bones by reducing the friction produced by gliding or sliding of the bones over each other.
Thus, to provide a smooth surface at the ends of synovial joint is the correct answer.
