The lungs.
The name of that organ is 'Pair of Lungs'.
The respiratory system is responsible for the exchange of gases between the atmosphere and the blood.
The air sacs (alveoli) have a very large total surface area and a very good blood supply. There is an exchange of gases between the air sacs and their surrounding capillary blood vessels. Oxygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac.
respiratory
The alveoli is the division of the respiratory system where gas exchange with the blood occurs. Oxygen from the inhaled air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled.
The blood exchanges gases in the lungs. Oxygen is taken in by the blood from the inhaled air, and the exhaled air contains traces of alcohol that the blood has exchanged with the air that was just inhaled. The Breathalyzer device that the police use can detect the alcohol in the exhaled air.

the respiratory system
Alveoli are the sack-shaped respiratory organs where blood picks up oxygen from the air during the process of respiration. These tiny air sacs in the lungs are surrounded by capillaries, allowing for the exchange of gases like oxygen and carbon dioxide.
The body system that exchanges o2 and co2 between blood and air is called the respiratory system. It is composed of the nose, windpipe, and lungs. It;s in the lungs that the exchange takes place.
In the lungs, oxygen from the air is taken up by red blood cells and carbon dioxide is released from the blood into the air when we exhale. This exchange of gases occurs in the alveoli, which are tiny air sacs in the lungs.
Tiny air sacs where the exchange of gases between air and blood takes place are located in the lungs. These air sacs are called alveoli and are surrounded by capillaries where oxygen from the air enters the blood and carbon dioxide exits the blood into the air.
