Oxygen moves from the lungs into the bloodstream through capillary blood vessels in the lungs.

Here's a step-by-step explanation:

1. When you inhale, air enters your lungs. This air contains oxygen.

2. The oxygen in the air passes into the tiny air sacs in the lungs, known as alveoli.

3. The walls of the alveoli are very thin and are surrounded by a network of tiny blood vessels, or capillaries.

4. Oxygen passes through the thin walls of the alveoli and the capillaries into the blood.

5. The oxygen-rich blood is then carried from the lungs to the heart, where it's pumped to the rest of the body.
