Question 14

The close connection between the respiratory and circulatory systems is essential for human survival. Given this statement, which of the following options best emphasizes the interdependence of these two systems in ensuring optimal oxygen delivery and carbon dioxide removal?

Accepted Answer

The respiratory system and circulatory system work together to deliver oxygen to cells and remove carbon dioxide.

Answer

The respiratory system brings in air while the circulatory system pumps it around the body.

Answer

The circulatory system provides oxygen to the body while the respiratory system removes waste gases.

Answer

The two systems work independently of each other.
