Respiratory System

The respiratory system consists of the nose, throat, larynx, trachea, bronchi and bronchioles and the lungs. As give vent passes by means of the emaciated cavities it is change and humidified, so that aura that reaches the lungs is warm and moist.  The Nasal tuneways ar lined with cilia and kept moist by mucose secretions. The combination of cilia and mucose helps to filter out squ are particles from the air an fiery and stifle the air, which prevents damage to the delicate tissues that change the Respiratory System. The wet in the nose helps to heat and wash the air, increasing the hail of water vapor the air immersion the lungs contains. This helps to keep the air entree the nose from drying out the lungs and another(prenominal) parts of our respiratory system. When air enters the respiratory system through and through the mouth, much little filtering is done.  It is generally better to take in air through the nose. The pharynx is also called the throat. As we aphorism in the digestive system, the epiglottis closes sullen the trachea when we swallow. Below the epiglottis is the larynx or express box. This contains 2 strain cords, which vibrate when air passes by them. With our vernacular and lips we alter these vibrations into speech. The area at the prime of the trachea, which contains the larynx, is called the glottis.

The trachea or trachea is made of muscle and elastic band fibers with rings of gristle. The cartilage prevents the tubes of the trachea from collapsing. The trachea is divided or branched into bronchi and so into littler bronchioles. The bronchioles branch off into alveoli. These tubes are lined with mucous-secreting cells and fine hairs called cilia. The mucous traps bacteria, dust and viruses. The cilia beat and progress to an upward current. This moves the mucous up and into the oesophagus. Here it goes to the stomach. When we clear our throats we quarter the mucous extraneous from our vocal cords. It is used to get unblock of irritants and excess mucous from our respiratory system. The lungs are...If you want to get a full essay, ramble it on our website: Ordercustompaper.com
