Respiratory System

Breathing inhaling and exhaling of air
Cyanosis bluish color of skin caused by oxygen deficiency in the blood
Diffusion moving of molecules from a region of higher concentration to a region of lower concentration of molecules
Eupnea normal respiration
Respiration exchange of oxygen and carbon dioxide
Inhalation phase during which air is drawn into lungs
Exhalation expulsion of air from alveoli of lungs
Cellular respiration use of oxygen and nutrients to produce energy, water, and carbon dioxide
Nose or mouth where air enters respiratory system
Cilia tiny hairs that filter out dust and other particles that enter the nose
Pharynx extends from mouth to esophagus; provides passageway for air from nostrils to trachea
Esophagus pathway for food, leads to the stomach
Epiglottis covers air only passage keeping food and liquid out of lungs
Larynx at upper end of trachea; contains vocal cords
Trachea windpipe, extends from larynx to bronchi
Bronchi branches of trachea leading to lungs
Bronchioles small tubes (thin as a strand of hair) in lungs branching from bronchi to alveoli
Alveoli tiny air sacs, where exchange of oxygen and carbon dioxide takes place
Lungs pair of lobed organs in chest cavity, extending from the diaphragm to the clavicle
Diaphragm muscle separating the abdominal and chest cavities; contraction of the diaphragm causes air to enter the lungs
Pleura serous membrane that covers the lungs and lines the chest cavity
Hyperpnea abnormally increased breathing
Apnea cessation of breathing
Anoxia lack of oxygen
Asphyxia oxygen deficiency with a resulting increase of carbon dioxide in the tissues
Dyspnea Painful or Labored breathing
Tachypnea fast breathing
Bradypnea slow breathing
Asthma allergic reaction in which the walls of the small bronchioles swell with a thick mucus secretion
Bronchitis the membranes lining the larger bronchial tubes become inflamed and an excessive amount of mucus is produced
Common cold most widespread of all communicable diseases, characterized by swollen and inflamed mucous membranes of the nose and throat with copious discharge
Cough mechanism for clearing obstructions from airway
Emphysema swelling of alveoli due to chronic bronchial obstruction
Epistaxis nose bleed
Hay fever sensitivity to foreign proteins causing watery discharge from eyes and nose
Influenza acute, contagious disease characterized by inflammation of the upper respiratory tract and generalized aches and pains
Pleurisy inflammation of the pleura – usually accompanies infections of the lung
Pneumonia inflammation of the alveoli of the lung – may be caused by bacteria or viruses
Sinusitis inflammation of a sinus
