Respiration The pharynx transport food to the oesophagus from

Respiration means the body’s ability to turn food molecules or glucose into energy for the cell to utilize, referred as the ATP. There are two types of respiration; they are the Aerobic and Anaerobic respiration.  The Aerobic respiration uses oxygen whilst the Anaerobic does not.The main function of the respiratory system is to assist the diffusion of oxygen into the bloodstream and to transport air into the lungs.THE NOSE. It is the only external organ of the respiratory system which takes part in the inhalation and exhalation of carbon dioxide. The internal part of the nose is lined with mucosa membrane which contains ciliated epithelium. The internal lining which serves as a viscid trap for any dust, bacteria and dust and helps the tract to moisture. The nose warms the air by the nasal passage to cool the body temperature. It also filters the air to prevent infections and the build-up of dirt that could interfere with gas exchange. The moistening of air to maintain the elasticity of the lungs is also performed by the nose. A disease that could affect the nose is the Common cold and the Hay fever.The pharynx is a muscular tube that connects the larynx and oesophagus to the nasal cavities. This is divided into three sections; the nasopharynx which, the oropharynx and the laryngopharynx. It is vital in vocalization. The pharynx transport food to the oesophagus from the mouth.The larynx is a tube-shaped organ in the neck and also called the voice box. It is made up of eight rigid hyaline cartilage rings and a spoon-shaped cartilage called the epiglottis. The thyroid cartilage is the largest of the hyaline. The larynx ensures the passage of air and food into the right direction and produces speech. Laryngeal cancer is a disease of the larynx as a result of smoking. The effect of smoking on the larynx is the throat cancer.The Trachea is secondary to the larynx. It is fairly hard because the walls are supported by C-Shaped rings of hyaline cartilage. The rings are incomplete and reinforce the trachea preventing collapse and keeping the airway clear. The trachea transports air into the lungs.The Bronchi are tubes that branch off into each lung from the trachea. Bronchioles are also smaller tubes that branch off from each bronchus. These both function to allow the passage of air into the lungs, where gas exchange takes place from the external environment.The main organ of the respiratory is the lungs and are contained in the thoracic cavity. They are divided into the left lung and the right lungs. The left lung has two lobes whilst the right has three lobes and each lung is covered with a double membrane named the pleural. It performs the exchange of carbon dioxide and oxygen with atmospheric air.The walls of the alveoli are made up of a single, thin layer of the epithelial cell.The alveoli are to get rid of carbon dioxide from the bloodstream, transport oxygen into the bloodstream and also sends tissues into the bloodstream. This is where gas exchange occurs.Inflammation of the throat. The hotness of smoke causes the lining of the throat to irritates and soften the passage of the nasal cavity. Smoking also causes the cilia to block and leads to the loss of the cilia’s fluidity. The presence of the blockage on the cilia cause the mucus to contest and therefore block up the trachea. The tar in the smoke softens the surface of the alveoli, therefore, reducing the contact surface of the blood vessels. Some chemical called the carcinogens which are found in the cigarette revitalize the development of cancer cells. some respiratory diseases are the Asthma, Lung cancer, Chronic bronchitis and so forth. Monoxide carbon holds itself together to haemoglobin in the bloodstream and stops it from transporting enough oxygen around the body. Chronic Obstructive Pulmonary Disease is likely to occur when someone smokes a lot and if this happens, it makes breathing extremely hard. Gas exchange is the transportation of oxygen from the lungs and removal of carbon dioxide from the bloodstream. Exchange of gas occurs in the alveoli, lungs and in the capillaries. Oxygen inhaled moves to the blood in the capillaries from the alveoli and carbon dioxide moves to the air in the alveoli from the blood in the capillaries. Emphysema which affects the alveoli are used for gas exchange. The walls of the air sac gradually becomes weak and are cause to damage
