Four Processes
Respiratory system
- Pulmonary ventilation (breathing): movement of air into and out of lungs
- External respiration: exchange of O2and CO2between lungs and blood
Circulatory system
- Transport of O2and CO2in blood
- Internal respiration: exchange of O2and CO2between systemic blood vessels and tissues
