Have you ever experienced swollen lymph nodes when you were sick? Why might this happen?
ivann1987 [24]

Answer:

Yes, swollen lymph nodes are more common than some might think.

Explanation:

The medical terms for swollen lymph nodes are adenopathy or lymphadenopathy.

Lymph nodes play a vital role in fighting off sickness in the body. They act as a filter, trapping bacteria and viruses before they can spread too far.

Lymph nodes <em>typically</em> swell up as a response to bacteria or viruses. Though cancer can be a factor in swelling, it is very rare. Most commonly they are felt right below the corner of the jaw, in the neck. Yet, they are not only in the neck; they are all throughout the body. When they are swollen, they might feel tender or even painful.

Alexus [3.1K]

The right option is A. hydrofluorocarbons

Hydrofluorocarbons are  pollutants that are likely to be produced from air conditioning.

Hydrofluorocarbons (HFCs) are synthetic fluorinated strong greenhouse gases that are strongly accumulating in the atmosphere. Hydrofluorocarbons are mainly used as refrigerants. Hydrofluorocarbons are used to replace ozone depleting substances such as chlorofluorocarbons and hydrochlorofluorocarbons which are being phased out in air conditioning, refrigeration, foam blowing agents, and solvents. Hydrofluorocarbons are responsible for about 20% of climate pollution by 2050
