Carbon monoxide binds to hemoglobin in red blood cells, preventing affected cells from carrying a full load of oxygen. Less oxygen from each heartbeat can be compromise heart functionality and at least increase hert rate.
Cancer-causing agents (carcinogens) in tobacco smoke damage important genes that control the growth of cells, causing them to grow abnormally or to reproduce too rapidly.
The carcinogen benzo(a)pyrene binds to cells in the airways and major organs of smokers.
Smoking affects the function of the immune system and may increase the risk for respiratory and other infections.
"There are several likely ways that cigarette smoke does its damage. One is oxidative stress that mutates DNA, promotes atherosclerosis, and leads to chronic lung injury. Oxidative stress is thought to be the general mechanism behind the aging process, contributing to the development of cancer, cardiovascular disease, and COPD.
•The body produces antioxidants to help repair damaged cells. Smokers have lower levels of antioxidants in their blood than do nonsmokers.
•Smoking is associated with higher levels of chronic inflammation, another damaging process that may result in oxidative stress."
thank you for your advice. do you however have answers to any of the specific questions in my post Arti?
Its easier to cut it down since it seems that you are in time.
