What is cellular respiration?
A chemical process in cells releasing energy for survival.
Gaseous exchange system components
Air passages, lungs, ventilation muscles
What does gaseous exchange involve?
Exchange of gases between air and blood in lungs.
Inhalation process
Diaphragm contracts downward, ribcage lifts
What triggers inhalation in breathing mechanics?
Contraction of the diaphragm and external intercostal muscles triggers inhalation.
Vital capacity definition
Max air exhaled after deep breath
What happens to lung pressure during exhalation?
Lung pressure increases during exhalation.
Gas exchange at alveoli
Oxygen diffuses into blood, CO2 diffuses out
Residual volume
Air remaining after forced exhalation
Breathing measurement tool
Spirometer
Difference in blood gas at alveoli
Deoxygenated blood arrives; oxygenated blood leaves
