Answer:
Because oxygen is circulated throughout the body via the bloodstream, there is a strong connection between the cardiovascular system and the <em><u>respiratory</u></em> system.
Explanation:
The cardiovascular system is responsible for the transport of oxygen to all tissues of the body, in addition to the removal of carbon dioxide, which depends on the close interaction with the respiratory system.
A summary of the strong connection between the cardiovascular and respiratory systems is
:
Blood contains red blood cells, which are responsible for transporting O₂ and CO₂ by binding to the hemoglobin molecule, present in these structures. The respiratory system is responsible for providing air with O₂ and removing CO₂, a process that depends on gas exchange at the level of the pulmonary alveolus.
