The lungsPneumonia is one of the organs of the respiratory system, helps sustain life. First, I want to talk about the shape and position of the lungs. The lung is an organ of the cone. They are located in the chest cavity, near the spine and on both sides of the heart. Next, I will mention lung structure. The lungs are separated into lobes by the left lung has 2 lobes slot: and lungs must have 3 lobes. The lungs are covered by a thin membrane called the lung tissue. Besides, the lungs are lined with a thin layer of the fluid acts as a lubricant to allow the lungs to slide smoothly when they expand and contract with each breath. The path to the lungs are divided into several levels. The branch to the trachea, lung, bronchus then continue branching bronchi, bronchioles and alveolar finally microscopie. The main function of the lungs is bring oxygen into the body and rid the body of waste gases such as carbon dioxide. In short, the lungs have a vital role, we can't stay healthy if the lungs have problem.
