List and briefly describe the natural processes that are part of the carbon-oxygen cycle.

The blood located in the heart's left ventricle, which is rich in oxygen, travels through the aorta artery to the whole body, where the blood (coming from the arteries) gives oxygen and "food" to the capillaries and receives carbon dioxide and waste, which then (throughly the veins) travels back to the heart's right atrium. Then, it goes from the heart's right ventricle to the lungs, where it "gives" carbon dioxide and waste and receives oxygen, which then returns to the heart's left atrium.
