Yes, both the mouth and nose help to moisten and warm air before it enters your lungs.
Into the lungs.
The deer most likely use their mouth or nose. They then expand their chest or lungs to withdraw the air from the atmosphere. The air then travels though the mouth or nose into the lungs.
It's an air pressure situation. When you breathe into a person's mouth you are creating positive pressure in their lungs. You are INFLATING the lungs. When to take you mouth away, the lungs deflate and the air comes back out. Blow air into a balloon then, if you do not keep the opening sealed, the air comes back out. Same priciple.
it goes to your 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.
Air passes from the environment into the nose/mouth, through the nasopharynx and oropharynx, into the glottis, trachea, bronchi and its bifurcations, and into the alveoli of the lungs.
After entering your nose and mouth, air travels down your windpipe (trachea) and into your lungs.
you breath and air comes out your mouth lol
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.
The structures of the respiratory system that prepare air for entry into the lungs include the nose and nasal cavity, which filter, warm, and humidify the air. The mucus lining the respiratory tract helps trap particles and pathogens, while the cilia in the airways sweep the mucus and trapped particles out of the respiratory system.
When the frog opens its mouth, Air flows in because it's in the nature of gases to flow from high pressure to low pressure ( Air to mouth ). When the air is inside the mouth of the frog, it closes its nose trills ( to avoid the escape if any air trapped ) and closes its mouth. When nose and mouth are closed, the air is trapped inside the mouth. Then, the frog raises its jaw which presses the air inside the mouth towards the lungs, because again, air under higher pressure (in mouth) goes to a place where there's lower pressure ( the lungs ). This is positive pressure inhalation. Then O2 is released from the air to the lungs, and CO2 is picked up. The frog then lowers its jaw, to lower the pressure in the mouth, to let the air travel from the lungs, to the mouth and into the outside, hope that helped!
you have to dod mouth to mouth so that if a person is not breathing then you pass air through your mouth to the other person's lungs to keep them ALIVE
