The mediastinum
The right lung is larger than left lung The left lung is made up of 2 lobes while right is made up of 3 lobes.
First it's larger, second the left lung is sharing space with your heart..
Your left lung is smaller. The right lung has three lobes: superior, middle and inferior. The left lung has only two lobes: the superior and inferior. The heart takes up the space that would have otherwise been used for a middle lobe on the left lung.
The left lung has 2 lobes due to the space occupied by the heart, which pushes against the left lung. The right lung has 3 lobes because it has more space in the chest cavity to accommodate the extra lobe.
the left lung is narrower than the right lung because of the amount of space the mediastinum (which includes the heart, blood vessels and others) on the left side. the left lung includes a cardiac notch where the heart lies.
The heart is (mostly) on the left side and takes up some space.
The left is smaller, due to the presence of cardiac notch
right lung
They are connected.
the left lung is smaller to make room for the heart.. the right lung has 3 lobes and the left lung only has 2 lobes..
The right Lung is slightly larger than the left, because the heart takes up some of the space on your left side. So, in order to make room for the heart, the left lung is smaller.
The cardiac notch is a feature of the left lung that accommodates the position of the heart. It allows the heart to fit snugly within the thoracic cavity and provides space for its proper functioning.
