The four chambered heart.
Because we have what is called a double-circulation system. The right and left side of the heart send blood to different areas of the body, and the blood must be kept separate. The right side sends deoxygenated blood from the body to the lungs to be oxygenated. The left side sends oxygenated blood from the lungs to the body. If there were a passage between the left and right ventricles, then a couple of things could happen. Some deoxygenated blood from the body would be recirculated to the body, decreasing the oxygen supply for the body's cells. Also, some oxygenated blood from the lungs would be re-circulated back through the lungs. It would make for a much less efficient system for oxygenating the body and ridding the body of carbon dioxide. ANy such opening would likely be surgically closed if at all possible.
not possible
one is the borrowing adaptation
Yes, there are.
Separation is possible by distillation.
Possible? It depends on the separation of the species ...but it is highly unlikely, even with scientific help.
It is not possible to anser the question since there is no separation of the numbers.

ok
theft is still possible when several employees are involved.
After my opinion a strict separation is not possible.
Simply put, the lungs don't get oxygenated blood. The lungs produced oxygenated blood by collected de oxygenated blood and expelling the carbon dioxide (breath out) and refilling with oxygen (breath in). This is a very simple and basic explanation but suffice to say that all this is made possible through tiny blood vessells which can absorb fresh oxygen and expel carbon dioxide via the lungs.
