ANATOMY

Detailed explanation-1: -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-2: -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-3: -A left lung with four lobes: a new discovery during the thoracotomy for recurrent primary spontaneous pneumothorax.

Detailed explanation-4: -Your left lung is smaller than the right because your heart is where the middle lobe on your left lung would be. Your left lung has two parts that your right lung doesn’t have: the cardiac notch (where your heart fits) and the lingula, an extension of the superior lobe.

Detailed explanation-5: -Traditionally, each of the hemispheres has been divided into four lobes: frontal, parietal, temporal and occipital.
