Vocabulary KEY Alveoli - One-celled, walled cluster of air sacs at the end of
the bronchiole. Apnea – Inability to breathe. Aspiration – Food gets pulled into the larynx. Bradypnea – Slow breathing. Cheyne-Stokes Respiration – Irregulary breathing pattern;
apnea followed by deep labored breathing. Cilia – Small hairs in nasal cavity. Dyspnea – Difficult breathing. External Respiration – Breathing, exchange of air between
the body and the outside envirorment. Hyperpnea – Abnormally deep breathing. Hypopnea – Shallow breathing.
Vocabulary KEY Conti. Internal Respiration – Bringing of oxygen to the cells and
the removal of carbon dioxide from them. Larynx – Voice box. Lungs – Main organ of the respiratory system; provide
the body with oxygen and eliminate carbon dioxide from the blood.
Orthopnea – Difficulty in breathing when lying down. Pleurae – Double layer membrane on the outside of lung. Pleural Cavity – Space between the two pleurae. Respiratory Tract – Passageways through which air moves
in and out of lungs. Tachypnea – Fast breathing. Trachea – Wind pipe.
Word Parts KEY Nasopharynx – Nose and throat. Oropharynx – Mouth and throat. Laryngopharynx – Larynx and
throat. Bronchitis – Inflammation of
bronchiole tubes. Pharyngorrhagia – Bleeding of
the throat. Sinusitis – Inflammation of
sinus. Rhinorrhea – Abnormal
flow/discharge from the sinus. Pleuralgia – Pain in the pleura
(side of body).
Tracheorrhagia – Bleeding in the trachea.
Hemothorax – Blood in the chest.
Pneumonia – Fluid in the lungs.
Pneumorrhagia – Bleeding in the lungs.
