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.
In humans, the lungs are located on either side of the heart in the chest, with the left lung sharing the left side of the space with the heart, which sits in an impression called the cardiac notch.n this image, lung tissue has been dissected away to reveal the bronchioles. The lung is the essential respiratory organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart.
