Unscramble the Blue Letters
Inside the airways and lungs, smoke increases the likelihood of infections, as well as croihnc diseases like btiirnhcos and emphysema. It does this by dnamiagg the cilia, tiny hairlike structures whose job it is to keep the airways clean. It then fills the alveoli, tiny air sacs that ebnale the exchange of oxygen and carbon dioxide between the lungs and blood. A toxic gas called carbon monoxide crosses that membrane into the blood, binding to hemoglobin and dincpsliag the oxygen it would usually have transported around the body. That’s one of the reasons smoking can lead to ogyexn deprivation and shortness of brtaeh.

Original Text
Inside the airways and lungs, smoke increases the likelihood of infections, as well as chronic diseases like bronchitis and emphysema. It does this by damaging the cilia, tiny hairlike structures whose job it is to keep the airways clean. It then fills the alveoli, tiny air sacs that enable the exchange of oxygen and carbon dioxide between the lungs and blood. A toxic gas called carbon monoxide crosses that membrane into the blood, binding to hemoglobin and displacing the oxygen it would usually have transported around the body. That’s one of the reasons smoking can lead to oxygen deprivation and shortness of breath.
