Flashcards in Chapter 11: Respiratory System Deck (110):
Small, hollow air sac
bronch/i or bronch/o
pneumon/o or pulmon/o
A little swelling
System consisted of nose, pharynx, larynx, bronchi, and lungs
Serves as an air passageway, warms and moistens inhaled air, cilia and mucous membrane trap dust, pollen, bacteria, and other foreign matter....
Passageway for air and for food, contributes to phonation as a chamber where the sound is able to resonate
Produces vocal sounds, the voicebox . High notes are formed by short,tense vocal cords. Low notes are produced by long, relaxed vocal cords. The nose, the mouth, pharynx, and bony sinuses aid in phonation and the tone that is produced to give each person a distinctive sound.
Provides an open passageway for air to and from the lungs. It is a semi-cylindrical cartilaginous tube
Provides a passageway for air to and from the lungs.
Bring air into intimate contact with blood so that the oxygen and carbon dioxide can be exchanged in the alveoli.
A narrow slit at the opening between the true vocal folds.
Covers the entrance of the larynx. During swallowing it acts as a lid to prevent aspiration of food into the trachea.
The two main branches of the trachea, that provide a passage way for air to the lungs. The right bronchus and the left bronchus. The right bronchus is larger and extends down in a more vertical direction than the left bronchus.
The depression that each bronchus enters the lung.
The organs of respiration. Each has an apex that is at the eternal end of the 1st rib, and a base that lies on the diaphragm. Each have lobes. The right lung has 3 lobes and the left has two lobes.
The air cells where the exchange of oxygen and carbon dioxide takes place
A substance formed in the lungs that regulates the amount of surface tension of the fluid lining the alveoli.
Infant Respiratory distress syndrome
In preterm infants, the lack of surfactant.
Adult Respiratory Distress Syndrome
Lack of surfactant, a substance formed in the lungs that regulates the amount of surface tension of the fluid lining the alveoli.
Tidal volume (TV)
Amount of air in a single inspiration and expiration. About 500 mL of air enters during normal quiet breathing
Vital capacity (VC)
Volume of air that can be exhaled after a maximal inspiration.
Total Lung Capacity (TLC)
Maximal volume of the air in the lungs after a maximal inspiration.
Medulla oblongata and the pons
Two of the structures of the brainstem, that regulate and control respiration
Regulated by the respiratory centre in the medulla oblongata
1st year. 20-40
5th year. 20-25
15th year: 15-20
Adult 12 -20
Pertaining to a small air sac in the lungs
Lung condition caused by inhalation of coal and silica, also called black lung
Temporary cessation of breathing.
Disease of the bronchi characterized by wheezing, dyspnea, and a feeling of constriction in the chest.
The partial collapse of a segment of alveolus decreasing the surface area available for oxygen and carbon dioxide exchange; condition of imperfect dilation of the lung
Chronic dilation of a bronchus or bronchi with a secondary infection that usually involves the lower portion of the lungs
Medical instrument used to visually examine the bronchi
Acute respiratory disease (ARD) characterized by obstruction of the larynx, a barking cough, dyspnea, hoarseness, and stridor.
Abnormal condition of the skin and mucous membrane caused by oxygen deficiency in the blood.
Cystic fibrosis (CF)
Inherited disease that affects the entire body, causing progressive disability and often early death
Condition of difficulty speaking. Hoarseness.
Chronic pulmonary disease in which the alveoli become distended and the alveolar walls become damaged and destroyed, making it difficult to exhale air from the lungs. Primary cause is smoking.
Good or normal breathing
Spitting up blood.
Condition of deficient amounts of oxygen in the inspired air
The process of breathing in
Inflammation of the larynx
Medical instrument used tonvisuallt examine the larynx
Surgical excision of a lobe of any organ or gland
Process of smelling
Inability to breathe unless in an upright or straight position
Also called whooping cough.
Inflammation of the pleura caused by injury, infection, or a tumor
Abnormal condition of the lung caused by the inhalation of dust particles such as coal dust
Inflammation of the lung caused by bacteria, viruses, fungi, or chemical irritants
Inflammation of the lung
A pathological condition in which there is a collection of air between the chest wall and the lungs, causing the lung to collapse
Tumor with a stem; can occur where there are mucous membranes, such as the nose, ears, mouth, uterus, and intestines
Pus in the chest cavity
Abnormal sound heard on auscultation of the chest; a crackling, rattling,mor dubbling sound
Surgical repair of the nose
Discharge from the nose
Rale or rattling sound in the throat or bronchial tubes caused by a partial obstruction
Chronic granulomatous condition that can involve almost any organ system of the body, usually the lungs, causing dyspnea or exertion
Inflammation of the sinus
Medical instrument used to measure lung volume during inspiration and expiration
Surgical puncture of the chest wall for removal of fluid; also called thoracentesis
New opening into the trachea
Infectious disease caused by the tubercle bacillus.
A little swelling
Test performed on sputum to detect the presence of mycobacterium tuberculosis, an acid-fast bacilli. Positive results indicate tuberculosis
Visual examination of the larynx, trachea, and bronchi via a flexible bronchoscope
Visual examination of the larynx via the laryngoscope.
Pulmonary function test
Series of tests performed to determine the diffusion of oxygen and carbon dioxide across the cell membrane in the lungs
Acquired immunodeficiency syndrome
Adult respiratory distress syndrome
Chronic obstructive pulmonary disease
Ear, nose, and throat
Human immunodeficiency virus
Infant respiratory distress syndrome
Postnasal drip, paroxysmal nocturnal dyspnea
Severe acute respiratory disease
Sudden infant death syndrome
T & A
Tonsillectomy and adenoidectomy
Total lung capacity
