RespiratorySystem 01

Respiratory System consists of the lungs and air passages responsible for taking oxygen
Nose it has two openings, called nostrils, through which air enters.
Nasal septum a wall of cartilage that separates the nose into nasal cavities.
nasal cavities the two hollow spaces in the nose
cilia tiny hairlike structures that help move the mucous layer that lines the airways pushing trapped particles toward the esophagus where it could can be swallowed
larynx the voice box, lies between the pharynx and the trachea
epiglottis a special leaflike piece of cartilage, closes the opening into the larynx during swallowing
pharynx the tube or cavity, with its surrounding membrane and muscles, that connects the mouth and nasal passages with the esophagus.
trachea windpipe, a tube extending from the larynx to the center of the chest
bronchi where the trachea divides into two, near the center of the chest
bronchioles in the lungs the bronchi continue to divide into smaller broncis
alveoli resemble a bunch of grapes, made of one layer of squamas epithelial tissue and contain a rich network of blood capillaries
lungs the division of the bronchi and alveoli are in the organs
ventilation the process of breathing, involves two phases inspiration and expiration
inspiration the process of breathing air intercoatel muscle contract enlarge thee thoracic cavity to create a vacuum
respiratory when the air rushes in through the airways to the alveoli
expiration air is forced out of the lungs and air passages
external respiratory the exchange of oxygen and carbon dioxide between lungs and bloodstream
internal respiratory the exchange of carbon dioxide and oxygen between the tissue cells and bloodstream
cellular respiration cells use the oxygen and nutrients to produce energy, water, and carbon dioxide
apnea lack of breathing
dysnea difficult breathing
tachypnea fast breathing
euphnea normal quiet breathing
hyperpnea abnormally increase of breathing
hyperventition slow,and shallow
asthma a respiratory disorder usually caused by sensitivity to an allergen such as dust, or animal fur
bronchitis an inflammation of the bronchi and bronchial tubes in acute or chronic form
COPD a term used to destructive any chronic lung disease that results in abstraction of the air ways
emphysema noninfectious, chronics respiratory condition that occurs when the walls of the alveoli deteriorate and lose their elasticity
laryngitis an inflammation of the larynx and vocal cords
pneumonia an inflammation or infection of the lungs characterized by a buildup of fluid in the lungs
