Alveoli
The small sac-like structures in the lungs are called alveoli. This is where the exchange of oxygen and carbon dioxide occurs with the bloodstream, a process known as gas exchange. Oxygen diffuses from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
The exchange of oxygen and carbon dioxide occurs in the alveoli of the lungs. Oxygen is taken up from the air into the bloodstream, and carbon dioxide is released from the bloodstream into the air in the alveoli during respiration.
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.
Oxygen and carbon dioxide are exchanged at the surface of the air sac. Oxygen is taken in from the air into the bloodstream, while carbon dioxide is released from the bloodstream into the air to be exhaled.
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.
The gas that passes from the bloodstream into the lungs is called carbon dioxide. Carbon dioxide is transported from the tissues to the lungs via the bloodstream, where it is exhaled out of the body during respiration.
The body eliminates carbon dioxide from the bloodstream through a process called respiration. When we breathe, we inhale oxygen and exhale carbon dioxide. The carbon dioxide is carried in the blood to the lungs, where it is then exhaled out of the body.
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.

These are called the "alveoli".
Oxygen and carbon dioxide travel into and out of the bloodstream via diffusion across alveolar and capillary membranes.

The respiratory system is responsible for the exchange of oxygen and carbon dioxide in the body. This process occurs in the lungs, where oxygen is taken in through inhalation and carbon dioxide is removed through exhalation. The oxygen is then transferred to the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled out of the body.
Mostly oxygen & carbon dioxide - but also some nitrogen.
