because of lung surfactrant
Ciliary dysfunction in the epithelial lining of the respiratory tract is responsible for the smoker's cough. Smoking damages the cilia, which are tiny hairs that help to move mucus and debris out of the airways. When cilia are impaired, mucus and irritants accumulate, leading to coughing as the body tries to expel them.
When smokers exhale, they release smoke and carbon monoxide along with other harmful chemicals from the cigarette into the air. This secondhand smoke can also be harmful to those around them, increasing the risk of health problems such as respiratory issues and heart disease.
Lowering the diaphragm too much when inhaling may cause excess pressure on the abdominal organs, leading to discomfort and potentially digestive issues. It can also restrict the ability of the lungs to fully expand, reducing the amount of oxygen taken in and impairing breathing efficiency. Over time, this can lead to respiratory problems and decreased lung function.
Yes, fat bodies, or adipose tissue, play a role in respiration indirectly. They store energy and produce hormones that can influence metabolic processes, including those related to respiratory function. Excess fat, particularly around the abdomen, can impact lung capacity and respiratory efficiency by restricting diaphragm movement. Thus, while fat bodies themselves are not directly involved in the mechanics of respiration, they can affect overall respiratory health and efficiency.
If the activation energy of a biochemical reaction is lowered, the reaction will occur more easily and at a faster rate. This is often achieved by the presence of enzymes, which act as catalysts to facilitate the reaction without being consumed in the process. Consequently, lowering the activation energy enhances the efficiency of metabolic processes within living organisms.
Yes. e.g not all asthmatics are smokers.
Respiratory infections
yes
it is a group of respiratory symptoms seen in smokers; includes coughing wheezing, vocal hoarseness, pharyngitis, dyspenia, and susceptibility to respiratory infections.
Secondhand smoke exposure can increase the risk of respiratory and circulatory diseases for non-smokers, although to a lesser extent compared to smokers. It can still have harmful effects on health, especially for individuals with preexisting conditions. It's important to minimize exposure to secondhand smoke to reduce the risk of developing these diseases.
Emphysema is not contagious, and someone with emphysema can be around a child with respiratory problems without endangering the child. Smokers should not be around a child with respiratory problems.
Respiratory Illness
For example, children living with smokers are twice as likely to have respiratory problems as children living with nonsmokers.
If a smoker is trying to expel mucus in the respiratory passages, that is done by coughing. Smokers often cough.
The tiny delicate cilia are killed by tobacco smoke; and as a result, smokers have few if any cilia remaining in their lungs. Because of this, and the constant irritation of smoke, smokers are much more susceptible to all sorts of respiratory problems.
