The organ that supplies a human's bloodstream with oxygen from the air is the lungs. When we inhale, air enters the lungs, and oxygen from the air diffuses into the bloodstream through the alveoli, tiny air sacs where gas exchange occurs. This oxygen-rich blood is then circulated throughout the body to supply tissues and organs.
Oxygen moves into the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
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 organ that supplies a human's bloodstream with oxygen from the air is the lungs. When we inhale, air enters the lungs, and oxygen from the air diffuses into the bloodstream through the alveoli, tiny air sacs where gas exchange occurs. This oxygen-rich blood is then circulated throughout the body to supply tissues and organs.
The lungs diffuse oxygen into the bloodstream. Oxygen from the air we breathe is absorbed into the bloodstream through the walls of the alveoli in the lungs, where it is then carried by red blood cells to be delivered to the body's tissues.
The lungs supplies the bloodstream with oxygen. When we breathe in, out lungs fill with oxygen and that oxygen is taken to the heart to keep our body going.
The respiratory system is responsible for exchanging carbon dioxide from the bloodstream for oxygen to be delivered to tissues. This process occurs in the lungs where oxygen is inhaled and carbon dioxide is exhaled.
The Heart
Oxygen moves into the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
The lungs are responsible for taking in oxygen from the air we breathe. Oxygen is then transferred from the lungs into the bloodstream to be carried to all the cells in the body.

The lungs are responsible for taking in oxygen from the air we breathe and transferring it into the bloodstream. This occurs through the process of gas exchange in the lungs where oxygen moves into the blood vessels in exchange for carbon dioxide.
