The chest contains two lungs, one lung on the right side of the chest, the other on the left side of the chest. Each lung is made up of sections called lobes. The right one has three lobes and the left one has two, to allow room for the heart beneath.The lung is soft and protected by the ribcage. The purposes of the lungs are to bring oxygen (O2), into the body and to remove carbon dioxide (CO2). Oxygen is a gas that provides us energy while carbon dioxide is a waste product or "exhaust" of the body. After entering the nose or mouth, air travels down the trachea or "windpipe". The trachea is the tube lying closest to the neck. Behind the trachea is the esophagus or "food tube". When we inhale air moves down the trachea and when we eat food moves down the esophagus. The path air and food take is controlled by the epiglottis, a gate that prevents food from entering the trachea. Occasionally, food or liquid may enter the trachea resulting in choking and coughing spasms. The trachea divides into one left and one right breathing tube, and these are termed bronchi. The left bronchus leads to the left lung and the right bronchus leads to the right lung. These breathing tubes continue to divide into smaller and smaller tubes called bronchioles. The bronchioles end in tiny air sacs called alveoli. Alveoli, which means "bunch of grapes" in Italian, look like clusters of grapes attached to tiny breathing tubes. There are over 300 million alveoli in normal lungs. If the alveoli were opened and laid out flat, they would cover the area of a doubles tennis court. Not all alveoli are in use at one time, so that the lung has many to spare in the event of damage from disease, infection or surgery. Many different muscles are used in breathing. The largest and most efficient muscle is the diaphragm. The diaphragm is a large muscle that lies under the lungs and separates them from the organs below, such as the stomach, intestines, liver, etc. As the diaphragm moves down or flattens, the ribs flare outward, the lungs expand and air is drawn in. This process is called inhalation or inspiration. As the diaphragm relaxes, air leaves the lungs and they spring back to their original position. This is called exhalation or expiration. The lungs, like balloons, require energy to blow up but no energy is needed to get air out. The other muscles used in breathing are located between the ribs and certain muscles extending from the neck to the upper ribs. The diaphragm, muscles between the ribs and one of the muscles in the neck called the scalene muscle are involved in almost every breath we take. If we need more help expanding our lungs, we "recruit" other muscles in the neck and shoulders. In some conditions, such as emphysema, the diaphragm is pushed down so that it no longer works properly. This means that the other muscles must work extra hard because they aren
