There are two lungs simply called the left and right lungs. These large structures take up most of the Thoracic Cavity which changes tize in order to pull air in or push it out of the lung. The right lung has three Lobes (parts that sit on top of each other) While the left lung has only 2. This is because the left ventricle of the heart sits over to the left and takes up some of the space the left lung would otherwise inhabit. The left lung has a curved gap for the heart called the Cardiac Notch.
because the heart is there
By lobes I assume you mean Pouches. (A 6-8 sided sponge) Basically.
Well this is a good question, and I will give it a good answer:
Lungs have these "Sponges" for a very good reason.
Surface area.
Think about this: Inside a balloon is a round wall that completes a shape.
Now, if you were to add in sponges that stick out a bit, while still allowing the wall to be shown, you could increase your "surface area" thus allowing the lungs to More effectively absorb air.
With ought these sponges, the lungs couldn't function as well as we need them to. They branch out and allow air to surround them on all sides. Allowing greater rates of absorption.
I hope this answers your question.
The left lung does actually have a small third lobe known as the lingular lobe, however it does not have three full lobes as does the right lung. This is because of the position of the heart in the left side of the chest.
There are two lobes in the left lung and three in the right
The lungs of a human contain five lobes. Three are located on the right side, and two are located on the left side.
The right lung has three lobes and the left has two.
the right lung is larger and has more lobes than the left, because the heart is normally located on the left side and takes up space where the lungs would have been.
Because the heart is on the left lung and there wasn't anymore room on the left lung.

The right lung contains three lobes. The left lobe only has two. Because of the heart on the left side, the left lung only has two lobes to make more room for the heart to pump on that side.
The Right lung has 3 lobes (superior, inferior & middle) while the left lung has 2 lobes (superior & inferior).
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.
The left lung is slightly smaller than the right lung because 2/3 of the heart is located there. The left lung contains the cardiac notch, an indentation in the lung that surrounds the apex (pointed end) of the heart. The smaller left lung only has 2 lobes, the superior and inferior.
The Right lung has 3 lobes (superior, inferior & middle) while the left lung has 2 lobes (superior & inferior).
The secondary bronchi go into the LOBES of the right and left lung. There are 3 lobes in the right lung and 2 lobes in the left lung, both having lobar bronchi.
right lung has 3 lobes (superior, inferior & middle) while the left lung has 2 lobes (superior & inferior)
After the mainstem bronchus, two secondary bronchi supply the left lung (and three supply the right lung).
The right lung has 3 lobes. This is in contrast to the left lung, which only has 2 in order to make room for the heart, which is located in the left side of the chest cavity.
The left lung does not have a middle lobe, this makes room for the heart.
well the right lung has 3 lobes and the left lung has only 2. its to give room for your heart.
There are 5 lobes in the lungs 3 on the right 2 on the left.
