asthma

A disease of the bronchi characterized by wheezing, dyspnea, and a feeling of constriction in the chest

bronchial tree

bronchi and their branches(bronchioles) that carry air from trachea to alveoli of lungs

bronchiole

small branch of the bronchi within lung

bronchus

one of two branches from the trachea to the lungs

bronchitis

Inflammation of the bronchial membranes

carbon dioxide

cartilage of the larynx

diaphram

musclulomembranous partition that separates the thoractic cavity from the abdominal cavity.

epiglottis

expiration or exhalation

glottis

trachea

cartilagenous muscular tube extending from the larynx to the bronchi (windpipe)

tuberculosis

Infectious disease caused by the tubercle bacillus, Mycobacterium tuberculosis. Most commonly affects the respiratory system and causes inflammation and calcification of the system.

vocal cords

two pairs of membranous bands in the larynx with the superior pair not having any part in speech and the inferior pair vibrating to produce sound.

cilia

hairlike projections that sweep particles towards the throat

external respiration

involves inhaling oxygen and exhaling carbon dioxide

hemoptysis

the expectoration of blood from the respiratory tract

dyspnea

difficult breathing

pneumothorax

a collection of air or gas in the pleural cavity

bronchoscopy

endoscopic exam of the bronchi

thoracentesis

collecting pleural fluid by passing a needle into the pleural space

internal respiration

movement of oxygen and carbon dioxide at the cellular level

rhonchi

Rales or rattlings in the throat

apnea

temporary cessation of breathing

epitaxis

medical term for nosebleed

anthracosis

Black lung desease, coal minors may be at risk of this desease

mucopurulent

pulmonary parenchyma

another name for alveoli
