Final answer:
The process of moving air into and out of the lungs is known as ventilation, which includes both inhalation and exhalation.Therefore, the correct answer is option C.
Step-by-step explanation:
The process of moving air into and out of the lungs is called ventilation. This involves two main actions: inhalation, which is an active process of drawing air into the lungs, and exhalation, which is typically the passive release of air from the lungs. While sometimes the term respiration is used to describe the overall process of getting oxygen into the body and releasing carbon dioxide, it actually encompasses much more than just breathing, including the exchange of these gases between the blood and body cells. Therefore, the correct answer is 'ventilation'.
