What will happen

Answer :

As we breathe in air we also exhale carbon dioxide. Carbon dioxide is produced in a cellular metabolism. It is produced as a waste product. Simultaneously most of the carbon dioxide is converted into bicarbonate. However, there is a proper mechanism of the circulatory system. There should be balanced concentration of carbon dioxide and oxygen. If blood rich in both concentrations get mixed, then this will disturb the human circulatory system as this will also combine carbon dioxide to combine with hemoglobin which leads to the formation of carbo-hemoglobin. This ultimately leads to the death of a person.

To avoid this from happening, the heart has four chambers. The two upper chambers are called the atria (singular: atrium) and the two lower chambers are called the ventricles. The partition between the chambers helps to avoid mixing up of blood rich in oxygen with the blood rich in carbon dioxide.
