Kelly’s way breathing and blood flow
VENTILATION
Mechanical movement of air
Air moving IN and OUT of the lungs
No gas exchange yet - just movement
Ventilation = Movement
Inhalation is the diaphragm contracting (flattens)
active process negative pressure (active process of getting the
dog back in the house)
Exhalation is diaphragm relaxing (dome)
PPPP – positive pressure passive process
(passive process of Letting the dog out of the house)

RESPIRATION
Gas exchange by diffusion (HIGH → LOW)
External Respiration
Oxygen: Outside air → Blood
Carbon dioxide: Blood → Lungs
Internal Respiration
Oxygen: Blood → Cells
Carbon dioxide: Cells → Blood
From the outside to the inside- alveoli to blood
And the inside to the way-way inside- blood to cells
