Mnenie [13.5K]

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:

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.
