RESPIRATORY SYSTEM
Are located in the head, neck and chest and is made up of the nose, pharynx, larynx, bronchi, bronchioles and lungs.
NOSE: It is in the middle of the face and in the middle ofthe orbits and above the mouth. The nose serves to filter, moisten and warm the air you breathe to give resonance to the voice and perceive odors.
PHARYNX: It's a common duct to the digestive andrespiratory systems.
LARYNX: It is then of the pharynx and is located in front of the neck. Its interior is called the glottis and has two pairs of folds: the upper part is called the vestibular folds(false vocal cords) and the lower vocal folds (true vocal cords). That vibrate to airflow producing the voice.Alpha
TRACHEA, BRONCHI AND BRONCHIOLES: the trachea is a tube that is located below thelarynx, esophagus front and consists of ring-shaped cartilage c. in its lower portion is divided into two branches which are the bronchioles each one of which is directed to the respective lung where inturn are divided into progressively smaller bronchi that branch into the bronchioles. serve to conduct air.
LUNGS: Are two organs located in the sides of the thorax having a truncated cone shapeat its lower base. The lungs are surrounded by a double membrane called pleura. Make external respiration.
BREATHING: Is a process by which it provides oxygen, removes carbon dioxide and producespower.
There are two types of breathing:
EXTERNAL RESPIRATION: Performed in the respiratory system and consists of two phases: the first is ventilation, which involves the passage of air through therespiratory tract. The introduction of air is called inspiration and is an active phenomenon because it requires that the respiratory muscles contract to expand the chest cavity; the diaphragm plays avery important because when connecting descends and greatly increases the length of this cavity.
The expulsion of air is called expiration and is a passive process. The second phase is external...
