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: -You have two lungs, the left lung and the right lung. 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 anterior border of the lung corresponds to the pleural reflection, and it creates a cardiac notch in the left lung. The cardiac notch is a concavity in the lung that formes to accommodate the heart. The inferior border is thin and separates the base of the lung from the costal surface.

Detailed explanation-4: -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-5: -With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen. This cycle repeats over and over again.
