Effects of Smoking on
Circulatory and Respiratory Systems


Smoking is very bad for your respiratory system. When you smoke a cigarette, you inhale the smoke into your lungs. Your lungs are exposed to 4,000 toxic substances in cigarette smoke.Smoking affects the respiratory system. When you smoke the tar sticks to the lining of your throat and lungs (fingers turn yelllow). Alveoli is a type of disease you can recieve. Smoking will affect your respiratory system and circulatory system because it contains a ton of carbon monoxide which sticks to the haemoglobin in the blood instead of oxygen this means that many organs don't get enough oxygen as they should do so it increases blood pressure so any small amount of oxygen can reach organs anyway.

Parts of the Respiratory System:



-Lungs -Diaphragm

Nutrition Tips : How Does Smoking Affect the Respiratory System?
All forms of tobacco, including cigars, pipe tobacco, snuff, and chewing tobacco, contain the addictive drug nicotine and can also cause cancer.88
Like cocaine, heroin, and marijuana, nicotine increases levels of the neurotransmitter dopamine, which affects the brain pathways that control reward and pleasure. For many tobacco users, long-term brain changes induced by continued nicotine exposure result in addiction — a condition of compulsive drug seeking and use, even in the face of negative consequences.89
