How does the smoking effect the respiratory System?
Smoking affects the respiratory system because it stops the small little hairs in your throat from working as well these small little hairs are called Cilia and are used to push dirt and mucus out of your throat so it can be breathed out or swallowed when reaches top of throat. The tar also sticks to the lining of your throat and lungs (this is the stuff which makes fingers yellow etc.).Smoking is also known to make alveoli in the lungs a more round shape than small cauliflower shape. This decreases the surface area and results in less oxygen filling lungs again leaving you of breath. It also affects your respiratory system and circulatory system because it contains a lot 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. This also means that less oxygen is swapped over in the gas exchange at the lungs
