PLEASE HELP 1. What are at least 3 specific health conditions that affect the lungs? 2. Why does it become more difficult for a tobacco user to breath over time? 3. Explain the connection between nicotine and cholestrol build up

1. Three of the most common lung diseases in women are asthma, chronic obstructive pulmonary disease (COPD), and lung cancer.

2.Because tobacco smoke contains carbon monoxide, this deadly gas displaces the oxygen in your blood, depriving your organs of the oxygen they need. Other chemicals found in cigarette smoke include acrolein, which can cause irreversible lung damage, and even in low amounts, it can cause a sore throat in 10 minutes.

3.Cigarette smoke raises levels of LDL, or "bad"cholesterol, and a blood fat called triglycerides. Those cause waxy plaque to build up in your arteries. At the same time, it lowers HDL, or "good"cholesterol -- the kind that prevents plaque from forming.

hope it help

thank you
