during the exchange of air in your lungs oxygen is being taken into into your bloodstream while substance is being released

The substance being released is carbon dioxide.

During the exchange of air in your lungs, the process of respiration takes place. Here are the steps involved:

1. Breathing in: When you inhale, air enters your body through the nose or mouth. It then travels down the trachea (windpipe) and into the bronchial tubes.

2. Bronchial tubes: The bronchial tubes divide and further branch out into smaller tubes called bronchioles. These tubes help in the transportation of air to the alveoli in the lungs.

3. Alveoli: At the end of the bronchial tubes, there are small grape-like clusters called alveoli. They are surrounded by tiny blood vessels called capillaries.

4. Oxygen exchange: In the alveoli, oxygen from the inhaled air passes through the thin walls of the alveoli and into the bloodstream. At the same time, carbon dioxide, a waste product generated by cells in your body, moves from the bloodstream into the alveoli.

5. Gas transport: Oxygen molecules attach to red blood cells in the bloodstream and are carried away to various parts of the body to supply oxygen to cells for their metabolic processes. Carbon dioxide, being a waste product, is transported back to the lungs through the bloodstream.

6. Exhaling: Once the oxygen is released into the bloodstream and carbon dioxide is gathered in the alveoli, you exhale. The carbon dioxide is then expelled from the body when you breathe out.

So, during the exchange of air in your lungs, oxygen is being taken into your bloodstream, while carbon dioxide is being released.
