Respiratory Test Flashcards
What are the four main processes of respiration?
Pulmonary ventilation, external respiration, transport of respiratory gasses, and internal respiration
What is internal respiration?
The exchange of oxygen and CO2 between body cells and blood in the capillaries
What is the exchange of oxygen and CO2 between body cells and blood in the capillaries called?
Internal respiration
What is the transport of respiratory gases?
When blood transports CO2 to the lungs and oxygen to the body’s cells
What is pulmonary ventilation?
Inspiration and expiration in response to changes in oxygen and carbon dioxide in the body
What is it called when blood transports CO2 to the lungs and oxygen to the body’s cells?
Transport of respiratory gases
What is inspiration and expiration in response to changes in oxygen and carbon dioxide in the body called?
Pulmonary ventilation
What is external ventilation?
The exchange of oxygen and CO2 between alveoli/blood in the pulmonary capillaries
What is the exchange of oxygen and CO2 between alveoli/blood in the pulmonary capillaries called?
External respiration
What does boyle’s law state?
That volume changes lead to pressure changes which then lead to the flow of gasses
What law states that volume changes lead to pressure changes which then lead to the flow of gasses?
Boyle’s law
Describe inspiration
The diaphragm moves inferiorly, intercostal muscles lift the ribcage, and pressure decreases
What is inspiration?
Inhalation
What do intercostal muscles do?
They lift the ribcage during inspiration
When is there lower pressure in the lungs?
During inspiration
What does the diaphragm do during inspiration?
It moves inferiorly
What is expiration?
Exhalation
