Respiratory System:
- The respiratory system is responsible for the exchange of gases, particularly oxygen and carbon dioxide, between the body and the external environment.
- It includes organs such as the nose, windpipe (trachea), lungs, and blood vessels.
Passage of Oxygen in the Respiratory System:
- Oxygen enters the respiratory system through the nose.
- From the nose, it travels through the windpipe (trachea).
- The windpipe branches into smaller tubes called bronchi, which lead to the lungs.
- In the lungs, oxygen diffuses into the bloodstream through the walls of tiny air sacs called alveoli.
- The oxygen-rich blood is then transported to the body's cells, where it is used for cellular respiration.
- Carbon dioxide, a waste product of cellular respiration, is carried back to the lungs through the bloodstream.
- In the lungs, carbon dioxide is expelled from the body when we exhale.
Correct Diagram:
The correct diagram illustrating the passage of oxygen in the respiratory system is:
