The entire process of exchanging gases between the atmosphere and body cells is called:
respiration
movement of air in and out of the lungs is called:
ventilation
Exchange of gases between the air in the lungs and the blood is called:
external respiration
Exchange of gases between blood and body cells is called;

lowers ph, more acidic
