What is the preferred gas delivery system in modern anesthesia practice?

Explanation:
The circle system is preferred because it reuses exhaled gases after CO2 removal, allowing low-flow anesthesia with stable oxygen and anesthetic concentrations while greatly reducing waste and cost. Its design—unidirectional valves, inspiratory and expiratory limbs, a CO2 absorber, and a reservoir bag—lets fresh gas mix with rebreathed gas, so the patient receives precisely controlled ventilation and warmed, humidified gas. Open or semi-open systems waste more gas and require higher fresh gas flows, making them less efficient and more costly, while the circle supports safer, economical, and environmentally friendlier modern practice.
