• Spoljašnje disanje: razmena gasova (O2 i CO2) između organizma i spoljašnje sredine

• Unutrašnje disanje: razmena gasova između krvi i ćelija; usvajanje gasova od strane ćelija

External respiration- gas exchange between environment & body by diffusion

Internal respiration – gas exchange between blood & cells & usage of gas by cells
