Rat, like all mammals, have noses and mouths which lead to the lungs. When rats breathe in the air, the oxygen travel to the lungs where gas exchange occurs.

no, it doesn't, but oxygen does.
Oxygen enters the blood stream through the air sacs in you lungs.
Kangaroo rats get oxygen the same way all mammals do - through their respiratory system, comprising the nose/mouth, trachea and lungs. Even in underground burrows, there is air.
Rats breathe through their nostrils. They have a well-developed respiratory system that includes lungs, allowing them to take in oxygen and expel carbon dioxide. Their breathing rate can vary depending on factors like activity level and environment.
It has to get oxygen and get rid of CO2
Blood picks up oxygen and releases carbon dioxide in the lungs.
Blood picks up oxygen and releases carbon dioxide in the lungs.
Because you suck in air through your mouth or nose and it goes into your lungs... it's called breathing =)
they enter the lungs in order to obtain oxygen and get rid of carbon dioxide. this process occurs in the alveolus of the lungs by diffusion.
