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.
<em> The other options do not show the correct order in which the oxygen travels from the alveoli to the tissues.</em>
Art conservation science, marine science, and nuclear science can be combined with science with another interest. Anyone can have this combination with a little knowledge from each of them but later, of course, they will study and will have a strong grip over the concepts of this combined study program.
You may learn biodiversity in conservation sciences while having a background knowledge you have learned in biology previously. Whereas marine science, which is also known as oceanography can also be a great choice. You study the physical and biological aspects of the oceans. Nuclear science is the most interesting one as you enter into the world of atomic particles.<span>
