Detailed explanation-1: -Overview. The heart and lungs are located in the thorax, or chest cavity. The heart pumps blood from the body to the lungs, where the blood is oxygenated. It then returns the blood to the heart, which pumps the freshly oxygenated blood to the rest of the body.
Detailed explanation-2: -The lungs are located on either side of the breastbone in the chest cavity and are divided into five main sections (lobes). The lungs are responsible for removing carbon dioxide from the blood and adding oxygen to it. The heart and lungs work together to do this.
Detailed explanation-3: -The lungs are inside the chest, protected by the ribcage and wrapped in a membrane called the pleura. The lungs look like giant sponges. They are filled with thousands of tubes, branching smaller and smaller. The smallest components of all are the air sacs, called ‘alveoli’.
