Oxygen is important to humans so we can breathe. we then give off carbon dioxide which plants need. Plants give off oxygen and the cycle repeats.
Your question makes no sense there is no such thing as "cell respiratory".
Your brain. It's what controls your body. You need oxygen supply to all parts of your body to survive. Without your lungs, heart, and circulatory system you would not be able to do this. And even though your brain directs these functions it needs oxygen to function. The most important thing a paramedic can do when trying to revive you is to keep the blood and oxygen moving by pumping your chest. This helps to keep your body alive, even though you are not breathing. I think there are more than one 'most important' parts.
Vascular system, also called the circulatory system. Look those terms up on wikipedia for more info.The answer to this is the circulatory system.The ciculatory system because the heart is in the ciculatory system and the blood is the most important thing in the circulatory system.Circulatory System
