ANATOMY

Detailed explanation-1: -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-2: -The left lung is slightly smaller and has a notch to give room for the heart. 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: -The left lung is located on the left of the heart and has a concave impression to accommodate the heart. This impression is known as the cardiac notch and it makes the left lung smaller than the right one. An important difference between the right lung and the left lung is the size.

Detailed explanation-4: -The mediastinum is the partition between the lungs and includes the mediastinal pleura. It is commonly applied to the internal between the two pleural sacs, the sternum and the thoracic vertebral column extending to the diaphragm.

Detailed explanation-5: -The human left lung is smaller and narrower that the right lung, and is divided into two lobes, an upper and a lower, by the oblique fissure.
