Chapter 21 : Respiratory Flashcards
What is the difference between inhalation and exhalation, in respect to pressure and volume?
When inhaling the volume inside the lungs increases while the pressure decreases
When exhaling the volume is going to decrease thus increasing the pressure within the lungs
Inhalation requires the engagement of what two muscles?
The external intercostals and the diaphragm
What is Respiratory Minute Volume
The volume of air moved per minute
Your breaths per minute + the volume of air moved with each breath will impact what aspect?
It will impact the respiratory minute volume, basically the amount of air moved out of the lungs each minute
What respiratory capacity involves accounting for the additional amount of air that can be breathed in after a normal inhalation?
Inspiratory capacity (think you inhaling to capacity)
External Reserve Volume:
the amount of air a person can forcibly exhale beyond a normal exhalation
What is the term that accounts for the amount of air that remains in a persons lungs after fully exhaling?
Residual volume
The addition of vital capacity and residual volume accounts for?
Total Lung capacity
