Over 17 million people in America live with a disease of the bronchial tubes called asthma. One out of every three asthma sufferers are under the age of eighteen. For years, asthma has been associated with environmental pollutants and lifestyle factors. Some studies have uncovered a high incidence of asthma in first-born children, suggesting a decreased immunity to allergens in new mothers. Experts debate... Read more >
Emphysema is an irreversible lung disease that affects approximately three million Americans. Emphysema destroys lung tissue, hindering the transport of oxygen between the lungs and the blood. Emphysema impairs respiratory function, causing breathing difficulties (dyspnea), and it can lead to serious secondary health complications, including heart failure. How Emphysema Affects the Respiratory System Emphysema... Read more >
High blood pressure in the arteries that transport blood from the heart to the lungs — the pulmonary arteries — is referred to as pulmonary hypertension or pulmonary arterial hypertension. As the blood is pumped through the arteries in the lungs, it receives oxygen; this oxygenated blood returns to the heart, where it is then transported to the rest of the body through the aorta and other arteries. Injury or... Read more >
Thousands of men and women alike are diagnosed with lung cancer each year in America. Of those diagnosed, most lung cancer patients have been cigarette smokers. Cigarette smoking is the single greatest risk factor for developing lung cancer, and yet the most preventable. Smokers and people exposed to secondhand tobacco smoke account for approximately 87 percent of all lung cancer cases. Though not... Read more >
The lungs are the primary organs of the respiratory system. The main function of the human respiratory system is to transport oxygen from the atmosphere into the blood, and to expel carbon dioxide from the body. Healthy levels of oxygen are absolutely crucial for the human body, as oxygen gives our cells energy and helps them regenerate. The Anatomy of the Lung Each lung is divided into lobes. The right lung... Read more >
Lung damage caused by emphysema cannot be reversed. Emphysema treatment concentrates on halting the progression of emphysema and controlling the symptoms. Quit Smoking Emphysema patients who smoke should quit as soon as possible. Quitting smoking will restore some lung function, and can sometimes halt the progression of emphysema. Quit... Read more >
An asthma attack is an episode of shortness of breath that requires treatment or medical intervention to restore normal breathing. At the time of the attack, the muscles around the bronchial tubes in the lungs are contracting and closing off the air passage that allows the movement of oxygen into and out of the lungs. The initial onset of an asthma attack allows an adequate amount of oxygen into the lungs but... Read more >
Asthma treatment is the focus of many research studies, in part because the disease is so common. Over 22 million Americans live with asthma, which causes chronically inflamed and swollen airways. In people with asthma, the lung airways spasm when exposed to asthma triggers, which can include allergens, strong fragrances, tobacco smoke, air pollution and even cold temperatures. Asthma symptoms vary widely... Read more >
