Quizplus · Accepted Answer

Carbon monoxide is a toxic gas present in cigarette smoke that can replace oxygen in the blood, leading to reduced oxygen delivery to the body's tissues, including the heart. This can increase the risk of cardiovascular disease among smokers. Carbon dioxide is a byproduct of metabolism that the body normally eliminates through respiration. Tar contains carcinogens and other harmful chemicals that can damage the lining of the arteries, leading to atherosclerosis, a major contributor to cardiovascular disease. Nicotine is an addictive substance found in cigarettes that can constrict blood vessels and increase heart rate, which can also contribute to cardiovascular disease. However, carbon monoxide is the primary cause among these options.
