How does the respiratory system affect the cardiovascular system

The air (oxygen) inhaled by the respiratory system is circulated through the blood to all over the body by the cardiovascular system.

Explanation:

The respiratory systems circulatory or cardiovascular system work together to circulate oxygen and blood to all the parts of the body. Air enters and exits from the lungs through the respiratory organs like trachea, bronchi, and bronchioles. Blood moves to and from the lungs to connect to the heart. Blood takes oxygen from the lungs to the heart than the heart pumps it to the different body parts.

So, the respiratory system is very essential to provide oxygen which is important for the cellular process. The cardiovascular system directly depends on the respiratory system and vice versa.

Thus, The air (oxygen) inhaled by the respiratory system is circulated through the blood to all over the body by the cardiovascular system.
