Oxygen enters through the nose but is involved with the
Respiratory System.
The respiratory system.
The respiratory system absorbs oxygen. Oxygen is inhaled through the nose and mouth, passes through the trachea, and enters the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
Arthropods have trachea through which air can circulate. Arthropods have very small openings in their body through which oxygen enters and is distributed throughout their 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.
Oxygen-poor blood enters the heart through the right atrium
Oxygen enters the body through the respiratory system. It is inhaled through the nose or mouth, travels down the trachea, enters the lungs, and then diffuses into the bloodstream through tiny blood vessels called capillaries in the lungs.
Oxygen enters the body through the respiratory system, specifically through the process of inhalation. It is taken in through the nose or mouth, travels down the trachea, and enters the lungs where it is exchanged with carbon dioxide.
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 rich air enters the body through the lungs.
Oxygen enters the respiratory system through the mouth or nose. It travels down the trachea and enters the lungs via the bronchial tubes. In the lungs, oxygen is diffused into the bloodstream through the alveoli. Oxygen-rich blood is then pumped by the heart to the rest of the body for cellular respiration.
