The Respiratory System and Looking at the Lungs

Looking at the respiratory system and the lung is like a fire necessary to burn oxygen. We usually do not consider body metabolism to burn, but that is to control the combustion of carbohydrates, fats, proteins and provide energy. The function of the respiratory system is to provide oxygen bound to billions of cells of these fuels and to eliminate waste of carbon dioxide.

Lung is part of the respiratory system. The lung looks like a pinkish gray cavernous tissue. The right lung is slightly larger than the left side and has three parts or leaves. There are two lungs in the left lung, and the heart occupies several rooms on the left side of the person's chest. The air sucked through the mouth or nose passes through the breathing tube or passage and branches into the main air passageway of the lungs called the bronchi. The bronchi descends along the right lung and descends from one lung. The bronchi branches into increasingly smaller tubes that deliver air to all parts of the lungs. They end up in a cluster called alveoli or small vesicles or air. Each lung contains millions of alveoli

The main organ of the respiratory system. Each corresponds to the structure of the conduction region and respiration region. The main function of the lung is to exchange oxygen and carbon dioxide with the air from the atmosphere. For this purpose, the lungs exchange breathing gas with a very large epithelial surface area of ​​about 70 square meters, which is very permeable to gas. The lung is a pair of cones connected to the trachea by the left and right bronchial tubes and the lungs are defined by the septum on the lower side. Septum is a flat domed muscle located at the base of the lungs and chest. The lung is surrounded by the pleura, and the pleura is attached to the mediastinum. The right lung is shorter and wider than the left lung, and the left lung occupies less volume than the right lung. The cardiac gap is a depression in the left lung surface and provides space for the heart (Figure 1).
