Ch 8 Flashcards
Respiration
Absorbing O2 and discarding CO2.
Homeostasis
State of equilibrium in the body
Inhalation can be called
Inspiration
Exhalation can be called
Expiration
Throat tube that leads to the openings for food and air
Pharynx
Opening that leads to the lungs
Larynx
Wind pipe
Trachea
Main branches of the lungs
Bronchi
Smaller branches of the lungs
Bronchioles
Small air sacs at the end of the bronchioles
Alveoli
Large muscle that contracts the lungs
Diaphragm
What structures make up the Upper Respiratory Tract (URT)
Nose, nasal cavity, sinuses, pharynx, larynx
What structures make up the Lower Respiratory Tract (LRT)
The trachea, bronchi, bronchioles, alveoli, and lungs
Phren/o
Diaphragm
Alveol/o
Alveolus
Membrane that surrounds each lung
Pleura
The space between the pleura that covers the lungs and the pleura that lines the thoracic cavity
Pleural cavity

Eupnea
Normal breathing, 15-20 breaths per minute
Dyspnea
Labored or difficult breathing
Apnea
Temporary absence of breath
Orthopnea
A condition where breathing is uncomfortable in any position except sitting erect or standing
Bradypnea
Slow breathing, less than 12 breaths per minute
Tachypnea
Fast breathing, more than 25 breaths per minute
Hyperpnea
Breathing that is deeper than normal
Hyperventilation
Increases aeration of the lungs, reduced CO2 levels, disrupts homeostasis
Spirometry
Measurement of the amount of air taken into and expelled from the lungs
Vital capacity
The max amount of air that can be exhaled after a max inhalation
Hypoxia, anoxia
Deficiency of oxygen
Inability of lungs to perform their ventilatory function is__________
Acute respiratory failure
Ism
Condition
