Answer

Oxygen

Explanation

## Step 1: Understanding the QuestionThe question is asking us to identify the gas that moves from the lungs into the bloodstream. This process occurs in the alveoli, which are small sacs in the lungs where gas exchange takes place. ## Step 2: Identifying the GasThe main gas that moves from the lungs into the bloodstream is oxygen. This is because, during inhalation, oxygen is brought into the lungs and diffuses across the thin walls of the alveoli into the surrounding capillaries. ## Step 3: Confirming the AnswerTo confirm our answer, we can refer to the basic knowledge of human respiratory system. Oxygen is the primary gas that our body needs for cellular respiration, which is the process of converting nutrients into energy. Therefore, it is the main gas that diffuses from the alveoli to the capillaries.
