12.1 Functions of the Respiratory System Flashcards
What is ventilation?
simple movement of air into and out of the lungs
What is respiration?
the exchange of gases between lungs and blood and blood and tissues
What is the conduction zone?
parts of the respiratory system that participate only in ventilation
What is the respiratory zone?
parts of the respiratory system that participate in actual gas exchange
What are the three additional tasks that the respiratory system performs?
- pH regulation
- thermoregulation
- protection from disease and particulate matter
What is hyperventilation?
too much breathing leading to alkalosis
What is alkalosis?
alkalinization of the blood
What is hypoventilation?
too little breathing leading to blood acidosis
What two components help the respiratory system protect us against harmful inhaled particles?
mucociliary escalator
alveolar macrophages
