Your lungs are located inside your chest cavity (thorax), on either side of your heart. They rest within the rib cage, separated from each other by the mediastinum, which contains the heart and other structures
- The right lung is larger and divided into three lobes, while the left lung is smaller, divided into two lobes, and has a cardiac notch to accommodate the heart
- The lungs have a broad base resting on the diaphragm and a narrow apex extending slightly above the first rib into the root of the neck
- Each lung is enclosed in a pleural sac made of two membranes (visceral and parietal pleura) that allow smooth movement during breathing
- The lungs lie against the ribs on their outer surfaces and face the heart and great vessels medially
In summary, your lungs are paired cone-shaped organs located in the thoracic cavity, flanking the heart and protected by the rib cage
