2) How many lobes do the lungs have? Why do you think that one side has fewer lobes than the other? There are 5 lobes in the lungs: 2 on the left, and 3 on the right. The left lung only has only 2 lobes because there has to be enough room in the chest for the heart, and the heart sits mostly behind the left lung.
Below the lungs is the diaphragm, a thin muscle that separates the chest cavity from the abdomen. Each lung is divided into lobes (sections): 1  The left lung has 2 lobes. 2  The heart sits in a groove (cardiac notch) in the lower lobe.3  The right lung has 3 lobes and is slightly larger than the left lung.elow the lungs is the diaphragm, a thin muscle that separates the chest cavity from the abdomen.
