Both, breathing through your nostrils act as a vent-like mechanism filtering out pollution from the air, and breathing through your mouth fulfills your lungs with the right amount of oxygen it needs.

Where do internal nostrils open?
The internal nostrils of the frog open into the frogs mouth. When the nostrils open it allows air to enter the enlarged mouth.

Trace the path of air through the respiratory system for a frog?
Respiratory system in a frog starts from the mouth, as the mouth expands the air is taken in through the nostrils. Then the nostrils starts closing and the mouth contracts causing the air to get inside the lungs. The body and lungs contract as the mouth opens giving out carbon dioxide. The exchange of air starts at respiratory bronchioles where oxygen is taken in and carbon dioxide is given out.
Where fresh air entres the body?
Air is sucked into the lungs through the nostrils of the nose or mouth.
What is the medical term meaning obstruction of the flow of air into the mouth and nostrils?
Asphyxiation
How do frogs get air into their lungs?
When air enters into the mouth through the internal nostrils. Air is drawn in by lowering of the floor of the mouth and then the floor is raised, causing the air to be forced out of the mouth. Valves in the external nostrils prevent the air from being forced back outside, and it is forced into the lungs.Frogs breathe by gulping air into their mouth and then closing their mouth and nares (nostrils). They then lift up their lower jaw and tongue to make the space inside their mouth very small. This increases the pressure of the air inside their mouth and the air moves from the mouth (high pressure) to the lungs (low pressure). Air always moves from areas of high to low pressure.Breathing out is passive (i.e. doesn't require energy) and the the high elasticity of the frogs body wall helps push the air out of the body.Read more in the related link.
Why is it better to breathe through the nostrils than the mouth?
There is improved filtering and warming of the air when breathing through the nostrils. Upper respiratory infections (and even lower respiratory infections) are less likely to occur in those who are not mouth breathers.
How do birds take in air?
Just like us, birds take in air through the nostrils or mouth.
What happens when excess air enters your mouth or nostrils when asleep?
lungs work more.
What is the sequence of the air passage into and out of a frog?
Respiration starts in the mouth. The mouth expands and oxygen-rich air is drawn in through the nostrils. Then the nostrils close and the mouth contracts, forcing this air into the lungs. The mouth opens as the body and lungs contract, expelling the carbon dioxide-rich air.
What is the function of the mouth on the system of respiration?
To allow the air to enter the body. The air can enter through either the nose or through the mouth.
What is one of the two places where air enters your body?
Air enters through your nose or mouth to your air sacs.
