Verified step by step guidance

Understand the definition of external respiration: External respiration involves the exchange of gases between the alveoli in the lungs and the blood in the pulmonary capillaries.

Identify the processes involved in external respiration: These include the diffusion of oxygen from the alveoli into the blood and the diffusion of carbon dioxide from the blood into the alveoli.

Analyze each option: Determine which processes are directly involved in the exchange of gases between the alveoli and the blood.

Consider the transport of carbon dioxide in the blood: This process involves the movement of carbon dioxide through the bloodstream to be expelled from the body, which is part of internal respiration, not external respiration.

Conclude which process is not part of external respiration: Recognize that the transport of carbon dioxide in the blood is not directly involved in the gas exchange at the alveolar level, distinguishing it from the other processes listed.
