Lungs

lung The respiratory organ of air-breathing vertebrates. A pair of lungs is situated in the thorax, within the ribcage. Each consists essentially of a thin moist membrane that is folded to increase its surface area. Exchange of oxygen and carbon dioxide takes place between blood capillaries on one side of the membrane and air on the other. The lung is supplied with air through a bronchus. The lungs are covered by a thin tissue layer called the pleura. The same kind of thin tissue lines the inside of the chest cavity -- also called pleura. A thin layer of fluid acts as a lubricant allowing the lungs to slip smoothly as they expand and contract with each breath.

Bronchial congestion

Bronchial congestion is more than a simple irritation, it affects everything from your breathing to your mood to the quality of your sleep, which we all know affects everything about your day. Whether you have acute bronchitis (comes on quick and leaves within a few days) or chronic bronchitis (suffer with bronchitis several days of the month, usually in smokers) there are home remedies that will help you relieve congestion.
The first thing to remember for treating bronchial congestion is to add water, both on the outside of the body and the inside. Increasing fluid intake keeps the linings of the bronchial tract moist and the mucous flowing so it can be expelled through coughing it up and out of the system.
