what are the surroundings of the lungs
The lungs are organs of the respiratory system that allow us to take in and expel air. In the breathing process, the lungs take in oxygen from the air through inhalation. Carbon dioxide produced by cellular respiration is in turn released through exhalation.he lungs are also closely associated with the cardiovascular system as they are the sites for gas exchange between the air and the blood. The body contains two lungs, of which one is positioned on the left side of the chest cavity and the other on the right side.
