The air you breathe in, travels through the trachea (windpipe) into the lungs through the bronchi. Inside the lungs, the bronchi divide into bronchioles that end in clusters or air sacs called alveoli. These air sacs have very thin walls filled with tiny blood vessels that carry the oxygen into the bloodstream. Continue reading “What is COPD?”
The air that we breathe in has oxygen which is absorbed into the body’s bloodstream. Our respiratory system has airways which are tubes that transport the oxygenated blood to the lungs. These tubes when narrowed and inflamed make it difficult to breathe. Asthma is a chronic lung disease that causes a spasm in the bronchus. The World Health Organization states that asthma is the most commonly found chronic disorder in children.
