Answer» <p>In the lung capillaries, the exchange of carbon dioxide and oxygen takes place.The right side of the heart collects carbon di oxide rich blood and after getting into lungs it picks up oxygen and become oxygen rich blood and the left side of the heart collects it and pumps into parts of the body.The one-way valves present in the heart prevents any backward flow of blood, sooxygen rich and carbondioxide rich blood cannot be mixed with each other.ButIf due to any abnormality blood starts flowing the wrong way, the blood gases (oxygen and carbon dioxide) might mix, which can cause serious threat to the body.</p> <p>what is the your name</p>
