Verified step by step guidance

Understand the context of gas exchange in the respiratory system. The process involves the movement of oxygen and carbon dioxide between the lungs and the blood.

Identify the different stages of respiration: Ventilation, External Respiration, Internal Respiration, and Cellular Respiration.

Ventilation refers to the physical movement of air in and out of the lungs, not the exchange of gases.

Cellular Respiration is the process by which cells use oxygen to produce energy from food, occurring at the cellular level, not in the lungs.

External Respiration is the correct term for the exchange of gases between the air in the lungs and the blood, as it involves the transfer of oxygen into the blood and carbon dioxide out of the blood.
