Inward only.
Oxygen enters the respiratory system through the nostrils or mouth, travels down the trachea, and then enters the lungs through the bronchial tubes. It then diffuses across the alveoli walls into the bloodstream where it is transported to cells in the body for energy production.
The respiratory system supplies oxygen to the blood through the process of breathing. When we inhale, oxygen from the air enters the lungs where it is absorbed into the bloodstream and then circulated throughout the body to supply cells with the oxygen they need for energy production.
Oxygen enters the respiratory system through the nose or mouth and travels down the trachea into the lungs. In the lungs, oxygen diffuses into the tiny air sacs called alveoli and is then transported into the bloodstream by binding to hemoglobin in red blood cells. The oxygen-rich blood is pumped by the heart to the rest of the body, where it is delivered to cells for energy production.
The respiratory system is responsible for providing the body with oxygen. It involves the process of breathing, where oxygen is inhaled into the lungs and then transported to cells in the body via the bloodstream.
Oxygen enters the body through the nose or mouth, then travels down the trachea into the lungs via the bronchial tubes. In the lungs, oxygen is exchanged with carbon dioxide in the alveoli, where it is absorbed into the bloodstream. The oxygen-rich blood is then pumped by the heart to the rest of the body's cells and tissues for energy production.
The pathway of oxygen is like a tube or pipe in the breathing system.

it helps you to breath and to live of the oxygen once the breathing system takes in the oxygen and gives it to the heart
Oxygen is transported first by air down the trachea and then transform to the hemoglobin of the blood to the cells. This is the pathway of oxygen in the human system.
Respiratory system
Breathing involves getting oxygen into your system and it expels carbon dioxide, which is a waste.
Air is used for breathing. Breathing is used to introduce oxygen into our system. Oxygen is necessary for life. Without breathing in air we would die.
