The lungs. It's part of your respiratory. your heart also helps, and it's part of the cardiovascular system
Lungs
I wouldn't exactly characterize it as separating carbon dioxide and oxygen, however, I think the answer you are looking for is the lungs which takes up oxygen into the bloodstream and expels carbon dioxide out of the bloodstream into the lungs so we can breathe it out again.
The oceans help provide an exchange of gases with the atmosphere by dissolving oxygen and carbon dioxide. Oxygen is essential for marine life to breathe, while carbon dioxide is important for regulating the Earth's climate through its presence in the carbon cycle.
The respiratory system is a collection of organs that take in oxygen from the air and expel carbon dioxide. The main organs involved in this process include the lungs, diaphragm, trachea, and bronchial tubes.
Carbon dioxide is chemical compound. Oxygen and nitrogen are chemical elements.
Their function is to rid the body of carbon dioxide and to provide oxygen to the cells of your body.
The lungs are the primary organs that take in oxygen and remove carbon dioxide from the body. Oxygen is taken in through the process of inhalation, and carbon dioxide is removed through exhalation.
The organ is gills.
The lungs are the organs where oxygen enters the body and carbon dioxide leaves it through the process of respiration. Oxygen is taken in when breathing and carbon dioxide is released when exhaling.
Pulmonary system- contains tissues and organs specialized for taking in oxygen and removing carbon dioxide from our bodies and for exchanging oxygen and carbon dioxide.
Well the trees provide us with oxygen, and we provide them with carbon dioxide. So if you planted more trees, we'd have more oxygen and they'd have more carbon dioxide! :D
Carry oxygen and nutrients to organs and carbon dioxide and metabolites away from organs

Lungs
providing oxygen becuase we breath in oxygen and breath out carbon dioxide and the plants need carbon dioxide to provide oxygen. Also they provide food for wild animals
Two organs in the chest are the lungs, responsible for breathing by bringing oxygen into the body and removing carbon dioxide, and the heart, which pumps blood throughout the body to provide oxygen and nutrients to cells.
