Final answer:
Nicotine affects the autonomic nervous system by increasing blood pressure and potentially causing arrhythmias. there is essentially no parasympathetic influence on blood pressure for the entire body. Additionally, the contradictory signals from nicotine can disrupt the regularity of the heart rate, potentially leading to arrhythmias.
Step-by-step explanation:
Nicotine, a drug found in tobacco products, affects the autonomic nervous system. It stimulates both the sympathetic and parasympathetic ganglia in the autonomic system, but its effects on the cardiovascular system are particularly notable. Nicotine increases blood pressure by enhancing the sympathetic input, as there is essentially no parasympathetic influence on blood pressure for the entire body. Additionally, the contradictory signals from nicotine can disrupt the regularity of the heart rate, potentially leading to arrhythmias.
