Respiratory Anatomy
This structure serves as a common passageway for food and air.
Pharynx
This term describes breathing air into the lungs.
Inspiration (inhalation)
A patient experiencing shortness of breath is displaying this symptom.
dyspnea
This term describes the amount of air moved during a normal, quiet breath.
Tidal Volume
This chronic condition causes inflammation and narrowing of airways, often producing wheezing.
asthma
This flap of cartilage prevents food from entering the trachea during swallowing.
epiglottis
During inhalation, this muscle contracts and moves downward.
Diaphragm
A patient with asthma experiences sudden wheezing and shortness of breath. This type of prescribed medication provides rapid relief.
Rescue inhaler (short-acting bronchodilator)
This term describes the additional air that can be forcibly exhaled after a normal exhalation.
Expiratory reserve volume.
This bacterial disease commonly affects the lungs and spreads through the air.
Tuberculosis (TB)
The right lung has this many lungs.
Three
These tiny air sacs are the main site of gas exchange.
Alveoli
A patient has a pulse oximeter reading 88%. This measurement indicates a potentially dangerous decrease in this.
Blood oxygen saturation.
This term describes the air remaining in the lungs after a maximal forced exhalation.
Residual Volume
This condition is an infection that inflames the alveoli which may fill with fluid.
Pneumonia
This thin, slippery membrane covers the lungs and lines the chest cavity.
Pleura
This gas diffuses from the bloodstream into the alveoli to be exhaled.
Carbon dioxide
A patient diagnosed with tuberculosis must be placed under this type of transmission-based precaution.
Airborne precautions.
This tool is used to measure lung function.
spirometer
This chronic lung disorder damages alveolar walls and reduces elastic recoil.
Emphysema
This space between the lungs contains the heart, trachea, esophagus, and major blood vessels.
Mediastinum
This term describes gas exchange between capillaries and lymph or body tissues.
Internal respiration
A patient with pneumonia has fluid accumulating in the alveoli. This interferes with the exchange of these two gases.
Oxygen and carbon dioxide.
This tool is used to measure oxygen saturation in the bloodstream.
Pulse oximeter.
This viral illness comes on quickly, causing fever, headache, muscle and body aches, and lethargy.
Influenza
