nasal cavities two hollow spaces in the nose
cilia tiny, hairlike structures
sinuses cavitoes in the skull that surrounf the nasal area
pharynx (throat) lies directly behind the nasal cavities
larynx (voicebox)lies between the pharynx and trachea
epeglottis closes the openings into the larynx during swallowing
trachea (windpipe)tube extending from the larynx to the center of the chest
bronchi enters the lungs and carries air from the trachea to the lung
bronchioles the smallest branch of bronchi
alveoli tissue and containa rich network of blood capillaries
lungs right lung has three sections; superior,middle, and the inferior. the left lung has only two lobes;the superior and the inferior
pleura membrane like sac the covers the lungs
ventilation the process of breathing
inspiration process of breathing in air
expiration air is forced out of the lungs and air passages
respiration the preocess of respiration is controlled by the respiratory center in the medulla oblongata of the brain
external respration exchange of oxygen and carbon dioxide between lungs and blood stream
internal respiration exchange of carbomn dioxide and oxygen between the tissue cells and the bloodstream
cellular respiration cells use the oxygen and nutrients to produce energy, water, and carbon dioxide
asthma a respiratory disorder usually caused by a sensitivity to an allergen such as dust, pollen, an animal, medications, or a food.
bronchitis an inflammation of the bronchi and bronchial tubes.
chronic obstructive pulmonary disease (COPD) a term used to describe any chronic lung disease that results in obstruction of the airways.
emphysema a noninfectious, chronic respiratory condition that occurs when the walls of the alveoli deteriorate and lose their elasticity.(smoking is usually associated with this)

influenza (flu) a highly contagious viral infection of the upper respiratory system.
laryngitis an inflammation of the larynx and vocal cords

pneumonia an inflammation or infection of the lungs characterized by exudate (a build up of fluid) in the alveoli.
rhinitis an inflammation of the nasal mucous membrane, resulting in a runny nose, watery eyes, sneezing, soreness, and congestion.
sinusitis an inflammation of the mucous membrane lining the sinuses
sleep apnea a condition in which an individual stops breathing while asleep, causing a measurable decrease in blood oxygen levels.
tuberculosis (TB) an infectious lung disease caused by the bacterium mycobacterium tuberculosis.
upper respiratory infection (URI) also known as common cold, an inflammation of the mucous membrane lining the upper respiratory tract.
