Nose or mouth
The nose is the best route for air to get into the lungs, as it is a better filter than the mouth. The nose decreases the amount of irritants that reach the lungs, whilst also heating and adding moisture to the air.
Mouth breathing is usually needed when exercising or when more air is needed, because the nose is not the most efficient way of getting large amounts of air into the lungs.
Journey down the windpipe
After entering the nose or mouth, air travels down the trachea or "windpipe". The trachea is the tube lying closest to the neck.
Behind the trachea is the oesophagus or "food tube". Air moves down the trachea when we inhale and food moves down the oesophagus when we eat.
The path air and food take is controlled by the epiglottis, a gate that prevents food from entering the trachea. Occasionally, food or liquid may enter the trachea, resulting in choking and coughing spasms.
Route into the lungs
The trachea divides into one left and one right breathing tube, termed bronchi. The left bronchus leads to the left lung and the right bronchus leads to the right lung. These breathing tubes continue to divide into smaller tubes called bronchioles.
The end of the trip
The bronchioles end in tiny air sacs called alveoli. Alveoli, which means "bunch of grapes" in Italian, look like clusters of grapes attached to tiny breathing tubes. There are over 300 million alveoli in normal lungs. If the alveoli were opened and laid out flat, they would cover the area of a doubles tennis court. Not all alveoli are in use at one time, so the lung has many to spare in the event of damage from disease, infection or surgery.

∙ 13y agoIt's due to differences in pressure, caused by the muscle known as the diaphragm, under your lungs. When you inhale, the diaphragm contracts. It makes there be more space in your 'pleural cavity' (the area in your chest around your lungs) and due to this, the pressure drops. As forces move to equalize the pressure inside and outside your body, air is drawn into the lungs, inflating them.

Where does air travel after it is taken into the mouth?
Into the lungs.
Do whales breath air through there lungs?
No. They breath using their lungs or with their lungs, but not "through" their lungs. They do however breath "through" their blowholes (to get the air in and out of their lungs).
How does oxygen travel from the air to the foetus?
Through the mother's lungs into her bloodstream, then across the placenta and through the umbilical cord to the fetus.
How can you breathe through your mouths and nose?
Your lungs circulate oxygen every time you inhale and exhale. They travel through your body when you inhale to the lungs and the lungs store the oxygen, and as you exhale, carbon dioxide from the air is released.
Air moves from the outside into the lungs through?
The air moves from the outside into the lungs through the windpipe.
What sort of things could make the lungs dirtyHow do these things get into the lungs?
A dusty enviroment can affect our lungs when we breathe it in because the dust particles can get trapped in our lungs which would affect our breathings the particles travel through the the air and we inhale it!
How do the lungs get the oxygen to the body?
The air enters through the mouth or the nose and is pulled down through the windpipe into the lungs. From the lungs, the oxygen molecules are dissolved in the alveoli and enter the red blood cells in the capillaries of the lung. From the capillaries, they travel to the heart and push oxygen through the body.
Where does air travel it taken into your mouth?
it goes to your lungs
What does air enter through?
Air enters through the trachea and into the lungs.
When air passes out of the lungs it is inspiration?
When air passes through your lungs it is called respiration.
Do reptiles breath air or lungs or water?
Reptiles breathe air - through their lungs.
What structure does air pass to get to the lungs?
