Your nose and mouth.
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 lungs absorbs oxygen into the blood
Gaseous exchange is the process of transferring oxygen from inhaled air into the bloodstream and removing carbon dioxide from the bloodstream into the exhaled air. This occurs in the alveoli of the lungs.
The lungs take in oxygen directly from the air.
The lungs take in oxygen from the air during respiration. Oxygen is absorbed into the bloodstream through tiny air sacs called alveoli in the lungs, where it is then transported to cells throughout the body.
The process of respiration takes in oxygen. In this process, oxygen is inhaled into the lungs and diffuses into the bloodstream where it is carried to cells to produce energy.
Exchange of carbon dioxide and oxygen takes place in the lungs through the process of respiration. In the lungs, oxygen from inhaled air is absorbed into the bloodstream, while carbon dioxide is released from the bloodstream into the lungs to be exhaled.

The lungs take in oxygen from the air you breathe. Inside the lungs, oxygen is transferred to red blood cells in the bloodstream through a process called gas exchange in the alveoli. The red blood cells then carry the oxygen to various parts of the body.
Gas exchange of carbon dioxide and oxygen takes place in the alveoli of the lungs. Oxygen from inhaled air enters the bloodstream through the alveolar walls, while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled.
Your body takes in oxygen through the respiratory system to help produce energy through a process called cellular respiration. Oxygen is transported via red blood cells in the bloodstream to all the cells in your body. These cells use oxygen to convert nutrients into energy that the body needs to function properly.

Humans exchange carbon dioxide and oxygen in the lungs through a process called respiration. Oxygen is brought into the lungs from the air we breathe and then transferred into the bloodstream, while carbon dioxide is released from the bloodstream into the lungs to be exhaled out of the body.
