Question

lo 4.1. what is the relationship between the cardiovascular and respiratory systems? they work together to deliver oxygen and remove carbon dioxide from the body. the cardiovascular and respiratory systems work together to deliver carbon dioxide and remove oxygen from the body. the respiratory system is responsible for delivering oxygen and removing carbon dioxide, while the cardiovascular system pumps blood. the cardiovascular system is responsible for delivering oxygen and removing carbon dioxide, while the respiratory system pumps blood. the cardiovascular system removes carbon dioxide from the body, while the respiratory system delivers oxygen.

Explanation:

The cardiovascular system (heart and blood vessels) transports oxygen - rich blood (after oxygen is picked up in the lungs) to the body's tissues and transports carbon - dioxide - rich blood back to the lungs. The respiratory system (lungs and airways) is responsible for taking in oxygen (from the air) and expelling carbon dioxide (a waste product). So, they work together to deliver oxygen and remove carbon dioxide from the body.
The second option is incorrect because the goal is to deliver oxygen and remove carbon dioxide, not the other way around. The third option is wrong as both systems are involved in the oxygen - carbon dioxide exchange process, not just separate functions of delivering/removing gases and pumping blood (the cardiovascular system does more than just pump blood in terms of gas exchange). The fourth option has the functions of the systems reversed. The fifth option also inaccurately separates the gas exchange function between the two systems; it's a collaborative effort.

Answer:

They work together to deliver oxygen and remove carbon dioxide from the body.
