MICROANATOMY

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 smaller because of the space taken up by the heart (see diaphragm for an image of this). Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes.

Detailed explanation-4: -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-5: -The lung is divided into right lung and left lung. The right lung is wide and short whereas the left lung is narrow and long. The right lung has a cardiac impression, and the left lung is very close to the heart. The common function of the lungs during respiration is to inhale oxygen and exhale carbon dioxide.
