Answer:

The respiratory system allows the entry of air with oxygen, which diffuses at the level of the alveolus-capillary barrier to the blood, and the circulatory system transports the oxygenated blood to cell of all tissues.

Step-by-step explanation:

The bioavailability of oxygen (O₂) in each cell of the body depends on the joint function of the respiratory and circulatory systems, which work together for this purpose.

  1. The respiratory system allows air, which contains O₂, to enter the lungs, leading it to the pulmonary alveoli.
  2. At the alveolar level there is a gas exchange barrier, the alveolus-capillary barrier, through which O₂ passes into the blood, while carbon dioxide from cellular maetabolism passes into the alveolus to be eliminated.
  3. Once O₂ is in the blood, it is transported through the circulatory system to all tissues, being used by the cells for the process of cellular respiration and energy metabolism.

Pulmonary respiration is a process that, in coordination between the respiratory and circulatory systems, allows cellular respiration.
