9. Which is the pathway of oxygen from lungs into the body tissues?
Setler [38]

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:

  1. O₂ from the air reaches the lungs.
  2. 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.
  3. O₂ in the red blood cells travels through the blood vessels.
  4. 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.

<em>     The other options do not show the correct order in which the oxygen travels from the alveoli to the tissues.</em>
