Detailed explanation-1: -Each lung is divided into lobes-the left lung has two and the right lung has three-which are similar to balloons filled with sponge-like tissue.
Detailed explanation-2: -The right lung consists of three lobes: the right upper lobe (RUL), the right middle lobe (RML), and the right lower lobe (RLL). The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL).
Detailed explanation-3: -Humans have two lungs: Right lungs are larger in size and are divided into three lobes. Left lungs are smaller in size due to the presence of a cardiac notch and are divided into two lobes.
Detailed explanation-4: -The left lung has only two formal lobes because of the space taken up in the left side of the chest cavity by the heart, though it does have the lingula, which is similar to a lobe.
