Carbon dioxide is produced inside all the cells of the body, as a metabolic by-product. Carbon dioxide does not enter through the lungs, rather, it leaves through the lungs.
Capillaries. The diffusion of nutrients, oxygen, carbon dioxide and wastes take place in the capillaries. If you want to be more specific, it would be the venous ends of the capillaries where carbon dioxide enters the blood.
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.
Both carbon dioxide and oxygen found in air enters through the stomata. More at Link
Oxygen and carbon dioxide travel into and out of the bloodstream via diffusion across alveolar and capillary membranes.
Carbon dioxide is very soluble in aqueous solutions. There is a lot less C02 in blood than in even flat soda. In general there is an equilibrium between C02 and H2CO3 and then H2C03 disassociates into H+ and HC03- and it is the change in pH that triggers the physiological response.

Oxygen enters the blood from the lungs through the process of gas exchange where it diffuses into the bloodstream from the alveoli. In the lungs, carbon dioxide exits the bloodstream and is expelled from the body through exhalation.
The process in which oxygen enters the bloodstream through the alveolus and carbon dioxide exits the bloodstream also through the same alveolus to be exhaled.

The tiny air sacs are called alveoli. Oxygen from the air enters the bloodstream through the walls of the alveoli, while carbon dioxide from the bloodstream is released into the air sacs to be exhaled.
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.
Carbon dioxide enters your body when you inhale air containing it. It is transferred from your lungs into your bloodstream, where it is carried to your body's cells. The cells then exchange carbon dioxide for oxygen through a process called respiration.

When you inhale oxygen, it enters your bloodstream and is carried to cells. As the cells use oxygen for energy, carbon dioxide is produced as a waste product. The carbon dioxide then diffuses into the bloodstream, travels back to the lungs, and is exhaled when you breathe out.

Mainly Carbon dioxide enters. Some water can enter,but majority of water leaves through them
