Only the right lung has a middle lobe.
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.
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 only has 2 lobes (superior and inferior) because the heart takes up much of the space allowed on the left side. The right lung; however, has 3 lobes (Superior, Middle, and Inferior). Yes. The left lung is a little less voluminous than the right lung. It has two lobes, whereas the right lung has three. Its volume is displaced a bit more, by the location of the heart, than the right lung.
Each lung has more than one "lobe" or section. The right lung has three, and the left lung has only two to leave room for the heart where the upper left lobe would be.
A cat has 7 lobes of the lung. The right side has 3; the right apical, right cardiac, and right diaphragmatic. The left also has 3; the left apical, left cardiac, and left diaphragmatic. There is one lobe directly in between both sides called the intermediate lobe.
Only the left lung has these features.
Caudate lobe drains into Left and Right Hepatic ducts; don't get confused with the Quadrate lobe of the liver which drains only into the Left hepatic duct.
Oh, dude, each lung has three lobes. The right lung has three lobes - upper, middle, and lower lobes, while the left lung only has two - upper and lower lobes. So, like, that's a total of six lobes between the two lungs. Cool, right?
well the right lung has 3 lobes and the left lung has only 2. its to give room for your heart.
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.
RML Pneumonia is "Right Middle Lobe" Pneumonia. The right lung has three lobes; the upper, middle, and lower. The left lung on the other hand only has two lobes; the upper and lower. RML Pneumonia refers to the location in the lung of the pneumonia, and not the virus or bacterial type itself.
