process of gas exchange in the body
Circulation
Respiration
Digestion
Flow of air in and out of the body; Breathing
Respiration
Pulmonary ventilation
External Respiration
Internal Respiration
Exchange of gases between the air spaces of the lungs and the blood in pulmonary capillaries.
In this process Blood gains oxygen and loses carbon dioxide
Respiration
Pulmonary ventilation
External Respiration
Internal Respiration
Exchange of gases between blood in systematic capillaries and tissue cells.
Respiration
Pulmonary ventilation
External Respiration
Internal Respiration
blood loses oxygen and gives carbon dioxide during production of ATP
