How do the respiratory and circulatory systems work together to get oxygen into your cells?

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.

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.

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