Examining the Physiology of Asthma

Asthma is thought to be one of the most common chronic and complex respiratory diseases including environmental and genetic factors (2). This condition of the respiratory tract is revealed by contraction of the bronchi and bronchioles responsive to the stimulus. The vascular resistance of the pulmonary system increases as the diameter of the blood vessel decreases as the contraction contracts. Normally healthy people spit 75-80% of their lung capacity. For people with obstructive pulmonary disease, this number is proportional to the state of airway lesions (1).

Asthma is a physiologically classified as reversible airflow obstruction and chronic airway disease that is pathologically associated with bronchoconstriction that narrows the respiratory tract of the lungs due to the contraction of the surrounding smooth muscle. Asthma affects children and adolescents worldwide, caused by the environment, hosts, genetic factors, and various fundamental factors. Symptoms and signs of asthma include chest tightness, wheezing, coughing, and breathing difficulties. - Automobile emissions, CO and asthma car emissions are a by-product of the combustion process of the engine and the loss of fuel. Studies have shown that 10% to 30% of vehicles are causing a majority of automobile-related air pollution despite an increase in the number of vehicles on the road. This fact sheet lists some air pollutants related to automobile exhaust emissions.

As air pollution increases, symptoms of asthma worsen. The etiology of asthma is not well understood and is incurable now. Asthma has many environmental factors. The main causes of environmental pollution are combustion of fossil fuels in combustion engines, dust from road traffic, and biomass for cooking and heating. In urban areas, high concentrations of particulate matter, nitrogen dioxide, ozone, and other volatile organic compounds are present, which can make breathing difficult. The health effects of particulate matter of different diameters are related to the length of particles remaining in the atmosphere and the location of respiratory infections. Children exposed to air pollution are very fragile. Therefore, children suck more pollutants than adults
