The right lung has four lobes. And the left lung has one.
Lung sizes do differ, but only marginally. This is true of all mammals. Even in the human, the right lung has three lobes and the left has two.
Pigs have 4 lobes in their right lung and 3 lobes in their left lung. The 3 lobes of the left lung are apical, cardiac, and diaphragmatic lobes.
If my memory is not at fault, a rat has 4 liver lobes.

The lung function of a rat is to take in oxygen you breath and take it to the blood. Then it releases the carbon dioxide from your body.
the rat and human anatomy is so simaler, its easy to tell the rat from the human. but it gets confusing. the rat has the same anatomy as a human but its smaller. if you do a disection of a rat you will find that the organs are there but there all moved over. some are in the same spots but then some are moved to a more safer spot. try a disection some time and you will see for yourself. D.K.
Rats must have a good sense of smell in order to locate food.
The differences is the size.
There are actually many differences. One is that both are part of the same food chain, the toad can eat a rat.
