Why does nicotine make it difficult for a smoker to quit using cigaretts
Nicotine has addictive properties that make it difficult for smokers to quit using cigarettes. When a person smokes a cigarette, nicotine is quickly absorbed into the bloodstream and reaches the brain, where it triggers the release of dopamine, a chemical that creates a feeling of pleasure and reward. Over time, the brain becomes accustomed to the regular release of dopamine and begins to crave nicotine in order to feel that sense of pleasure and reward again.
This addiction can make quitting smoking a difficult process. When a person tries to quit smoking, they may experience intense cravings for nicotine, as well as withdrawal symptoms like irritability, anxiety, difficulty concentrating, and sleep disturbances. The physical and psychological dependence on nicotine can make it difficult for a smoker to quit smoking and lead to relapse even after making initial progress.
Quitting smoking may require a combination of support, counseling, and medication to help overcome the addiction to nicotine and manage withdrawal symptoms. It is important to note that quitting smoking is a significant accomplishment that requires ongoing effort and dedication.

Describe how intoxication affects the excretory system.
A. drinker loses more water from the body B. more blood flows to the skins surface
C. sensations and perceptions become less clear
D. too much alcohol in the stomach may couse vomting
The correct answer is:
A. Drinker loses more water from the body.
Intoxication can affect the excretory system in many ways, but one of the most significant effects is that it can cause the body to lose more water than it normally would. When a person consumes alcohol, it acts as a diuretic, which means that it increases urine production and can cause the body to lose fluids more rapidly. This effect can lead to dehydration, which can cause symptoms like fatigue, headaches, dizziness, and a dry mouth or throat. In severe cases, dehydration can lead to serious health complications, such as kidney damage or failure.
Other effects of alcohol on the excretory system can include decreased function of the liver, which plays a key role in processing and detoxifying alcohol in the body. Alcohol can also irritate the stomach lining, leading to nausea, vomiting, and diarrhea, which can further dehydrate the body. Additionally, alcohol can affect the bladder, causing urgency and frequency of urination, and may lead to incontinence in some people. Overall, excessive alcohol consumption can have serious effects on the body's excretory system and can lead to a range of health problems.
