If we do have a test on Monday about the physical effects caused by using tobacco, I am going home and study right now. Bye, Savvy, see you tomorrow.
This year's health class is really different from last year. Let's hope we won't have so much test any more.
Hello again, my fellow students! Remember what I said last week? We are going to talk about how the tobacco company want kids to use tobacco products. But first, let's review the physical effects caused by using tobacco.
How tobacco companies want kids to use tobacco products?
Cigarettes contains nicotine which cause addiction. When a smoker is smoking, the nicotine first enters the lung, then went to the blood strain, within ten seconds, the nicotine would reach the smoker's brain. In the brain, nicotine would attach to the nicotine receptors, which would then cause the release of dopamine, which makes the smoker feel good. The more the smoker smoke, the more nicotine receptors he will have, which means the smoker have to smoke more and more to feel the same feeling of joy.
Smokers may also have emotional swing. Smokers under nicotine withdrawal become irritable, depressed and anxious. They have trouble sleeping, are likely to want to eat to compensate for the loss of pleasure and start to crave their next cigarette.
The nicotine in cigarettes causes narrowing of the blood vessels in the outermost layers of your skin. This impairs blood flow to your skin. With less blood flow, your skin doesn't get as much oxygen and important nutrients.
Good Job! let's move onto the long term effects. How about we start with you, Hanson.
