docker41 [41]

The following are the ways to keep the lungs free of germs and dirt from the air:

Mucus found in the bronchial tubes collects dirt and germs that gets into your lungs.

Tiny hairs called cilia work to sweep out the debris collected to keep your lungs clean.

<u>Explanation</u>:

The lungs are air-filled organs that are responsible for breathing. Lungs are located on either side of the chest. Exposure to pollutants should be avoided to maintain the lungs healthy and clean.

Cilia are tiny hair-like cell structure that is located on the surface of the cells. These tiny hairs help in sweeping out the collected debris to keep the lungs clean.

Mucus is a substance secreted by the mucous membranes and is found in the bronchial tubes. The dirt and germs are collected by mucus and prevents that from passing into the lungs.

Which of the following is a classification of illegal drugs? A. antidepressants B. hallucinogens C. antihistamines D. painkiller
4vir4ik [10]

The correct answer is B, hallucinogens.

Antidepressants are most definitely legal, tons of people are on them. It is illegal to sell them, though (unless you are a pharmacist).

Painkillers are the same way, and many times otc.

Antihistamines are similar to painkillers, mostly used for allergies, and the name brands are extremely common; Zyrtec, Claritin, Allegra and Benadryl.

Meanwhile, hallucinogens are drugs such as LSD, PCP, ketamine, mushrooms. These wildly impact human mind and body and are therefore illegal.

(I would like to mention that ketamine is an antidepressant, but now identified more so as a hallucinogen due to the fact that it's effects last about an hour. This has caused it to become a party drug called "crazy k" which is often times laced with cocaine.)
