Answer:
The pathway of oxygen from lungs to the body tissues is alveoli → red blood cells → blood vessels → tissues (option b).
Explanation:
The oxygen (O₂) required by the tissues comes from the air inspired by the respiratory system. The pathway of entry of O₂ to the body and tissues is:
- O₂ from the air reaches the lungs.
- In the pulmonary alveoli, gas exchange occurs, that is, O₂ passes into the blood capillaries and is captured by the red blood cells, while CO₂ is released and passes into the alveoli to be eliminated.
- O₂ in the red blood cells travels through the blood vessels.
- The tissues receive the O₂ and a second gaseous exchange occurs at the tissue level, as they release CO₂ that will be carried to the alveoli.
Tissue oxygenation depends on the integrity of the respiratory and circulatory systems.
