What is the trachea?
The larynx is connected to a long to a long tube called the trachea, or windpipe. Air flows from the larynx through the trachea to the lungs. The trachea splits into two branches called bronchi. One bronchus connects to each lung. Each bronchus branches into smaller tubes called bronchioles.
What are some disorders of the respiratory system?
Some are asthma, pneumonia, emphysema, and lung cancer. Some respiratory problems such as emphysema and lung cancer are strongly linked to cigarette smoke. Other respiratory disorders such as pneumonia are caused by pathogens and some genetic disorders.
What is asthma?
Asthma is a condition in which the airways are narrowed due to inflammation of the bronchi. During an asthma attack, the muscles in the bronchi tighten and the airways become inflamed. This reduces the amount of air that can get in and out of the lungs.
What is pneumonia?
Pneumonia is an inflammation of the lungs that is usually caused by bacteria or viruses. Inflamed alveoli may fill with fluid. If the alveoli are filled with too much fluid, then the person cannot take in enough oxygen and they may suffocate.
What is emphysema?
Emphysema occurs when the alveoli have become damaged. As a result, oxygen cannot pass or cross into the blood as well as it could in a normal alveolus. People who have emphysema have trouble getting the oxygen they need and removing CO2 from their lungs. This condition is often linked to long-term use of tobacco.
