Question
Answer
What is tidal volume   the normal amount of air exhaled during resting breathing  
🗑
what is the normal tidal volume   500ml  
🗑
What is minute respirator volume (MRV   The total amount of air a person breathed out during 1 minute.  
🗑
How is MRV calculated?   MRV = TV x Respiratory Rate (number of breaths in 1 minute)  
🗑
Whate is Expiratory reserve volume (ERV)   the amount of air forcibly exhaled after a normal exhalation has occurred  
🗑
what is the normal ERV   1200ml  
🗑
What is Vital Capacity?   The total amount of air a person can exhale  
🗑
what is the spirometry equation   VC = TV+IRV + ERV  
🗑
What is quiet breathing   squeezing up with diaphragm  
🗑
forced breathing   squeezing up with diaphragm and in with ribs  
🗑
what is pulmonary ventilation   breathing  
🗑
what is internal respiration or inspiration   when the air goes into the lungs  
🗑
what is external respiration or expiration   when air passes out the lungs  
🗑
what organs are used in inspiration   nose>pharynx>larynx>trachea>Bronchi>aveoli ducts>aveoli>blood  
🗑
From lungs to blood chemistry   hhb>hbo2  
🗑
from blood to tissue chemistry   hbo2> HHB + O2  
🗑
From tissue to blood (waste chemistry)   CO2 + H2O > H2CO3 (makes carbonic acid)
