Respirations Flashcards
Flow of air into and out of alveoli is called?
Ventilation
Flow of blood into alveolar capillaries is called?
Perfusion
Inhaling of oxygen and the exhaling of carbon dioxide is called?
Respirations
A complete or partial collapse of the entire lung or area (lobe) of the lung.
Occurs when tiny air sacs (alveoli) within lung becomes deflated or possibly filled w/ alveolar fluid.
Called?
Atelectasis
The process by which oxygen and carbon dioxide move between the bloodstream and the lungs is called?
Gas exchange
How are respirations regulated?
Chemoreceptors sense levels of CO2, O2, pH of blood and alter respiratory pattern to maintain homeostasis
The pressure of tissues in the airway to the flow of air is called?
Airway resistance
What is volume of air inhaled during a typical inhalation called?
Inspiration respiratory reserve
What is the volume of air inhaled and exhaled called?
Tidal volume
What is the volume of air in alveoli after exhalation called?
Residual volume
What is volume of air remaining in lung after maximum inhalation called?
Forced vital capacity
What is the max volume of air that is exhaled after max inhalation called?
Vital capacity
What is the volume of air remaining in lung after max inhalation called?
Total lung capacity
