The respiratory system is an intricate web of variety meats all working together to see a changeless flow of gases. O and C dioxide. to maintain the organic structure working at remainder or during exertion’ ( ehow ) . The respiratory system is made up of the olfactory organ. windpipe. bronchial tube. stop and lungs. The purpose of this assignment is to look at the construction and maps of the respiratory system and besides supply an illustration of the respiratory system. . The lungs are an built-in portion of the human organic structure. and the O provided by the lungs facilitates life. The human organic structure contains two lungs in the thorax. one on the right side of the thorax and a somewhat smaller lung. to ease room for the bosom. on the left. Each lung is between 10 and 12 inches long and contains blood vass that carry C dioxide blood in and oxygen blood out to the remainder of the organic structure. Bronchial tubings are besides present in the lungs which contain over 300million air sacs known as air sac. The chief map of the lungs is to execute gas exchange and to assistance in waste remotion and regulate in temperature control.

Air is breathed in through the olfactory organ or oral cavity or both which travels down the trachea which is called the windpipe which is so branched into the left and right bronchi’s which lead to the lungs. Harmonizing to the American Heart Association ‘the right bronchial tube has a shorter much direct. path to the right lung than does the bronchial tube to the left lung. ’ Each of these bronchi’s subdivisions into smaller tubing called bronchioles. This system is referred to as the bronchial tree. At the terminal of each bronchial are little air pouch called alveoli’s. These are responsible for interchanging C dioxide and O. Alveolus is closely situated to blood capillaries. Oxygen and C dioxide diffuse across the thin membranes that separate the capillaries from the air sac. conveying oxygenated blood throughout the organic structure and taking C dioxide from the lungs through halitus.

Lungs need to be protected against diseases and infections to maintain them executing their chief map of gas exchange. and they do this by several ways. First the nose Acts of the Apostless as a filter external respiration in and pin downing big atoms. The smaller atoms get trapped by a thin bed of mucous secretion known as emotionlessness that lines the interior of the external respiration tubing. ‘An norm of 3ounces of mucous secretion is secreted onto the liner of these take a breathing tubings every day’ ( livestrong ) . This mucous secretion is so swept up towards the pharynx by the cilia where it is so swallowed. Coughing is besides another manner to protect the lungs as it aids in taking mucous secretion quicker than the cilia. Many different musculuss are used in the respiratory procedure. The largest and most efficient is the stop which is a big musculus that is situated under the lungs. During inspiration the stop moves downwards and the lungs expand with air. During halitus the stop relaxes and the lungs return to their original form. . This assignment has looked at the respiratory system with mention to the construction and designation of the system. It besides has provided an illustration of the system.
