Lungs, The organs of respiration . They are two, and occupy the thorax, the upper part of the trunk. They fit exactly into this conical space,but do not meet in the middle. The heart is placed between them.Their function is to remove the carbon dioxide from the blood and replace it with oxygen. At every beat the heart pumps blood into their veins , which divide into very small branches,where the blood is brought into contact with the air in the air cells at the ends of the smallest division of the air tubes.

Answer
◇The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax).
◇The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi.
◇The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
