FranOxygen enters the body through the mouth or nose, passes through the trachea (windpipe), then enters the bronchial tubes in the lungs. Within the lungs, the oxygen is absorbed by tiny air sacs called alveoli and then enters the bloodstream to be transported to cells throughout the body.

What Pathway bof oxygen in the breating system?
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.
What is the pathway of hemogobin of an oxygen molecule in the body?
Oxygen is inhaled into the lungs and binds to hemoglobin in red blood cells. Hemoglobin then carries the oxygen-rich blood through the arteries to tissues in the body where it is released for cellular respiration. The oxygen-depleted blood returns to the lungs through the veins to pick up more oxygen.
What is the oxygen pathway when we breathe in?
When we breathe in, oxygen enters through the nose or mouth and travels down the windpipe (trachea) into the lungs. In the lungs, oxygen is absorbed by tiny air sacs called alveoli and then enters the bloodstream through tiny blood vessels called capillaries. The oxygen-rich blood is pumped from the lungs to the rest of the body by the heart, where it is used for energy production in cells through a process called cellular respiration.
Trace the pathway of oxygen to an internal cell?
Oxygen enters the body through the respiratory system, where it is inhaled and travels down the trachea into the lungs. In the lungs, oxygen diffuses into the bloodstream through the alveoli. The oxygen-rich blood is then pumped by the heart to various parts of the body through arteries, eventually reaching individual cells where it is used in cellular respiration to produce energy.
How will you describe the pathway of oxygen into the breathing system?
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.
