The nose and mouth are entry-ways for either air, food, or drink, and they meet together behind the face at an area called the pharynx (we call it the 'throat'). The pharynx is only about 5" long (give or take), & leads to two pathways: the trachea (or 'windpipe', in the front, where air enters) or the esophogus (behind the trachea; for food/drink).
Every time you breathe, eat, or drink, your body makes a decision as to where it will send the substance. For instance, when air is detected the body sends it from your pharynx (throat) down the trachea (a.k.a.; wind pipe) to the bronchial tubes that branch off to the left and right sides of your chest (lungs). On the other hand, if the body detects food or drink it will send it down the esophogus to the stomach without you even thinking about it!
However, in order for the air or food to go the right way, it must be directed. That job is being done by a little flap of cartilage covering the trachea called the 'epiglottis'; and boy, is it a busy thing during mealtimes! Just think: before taking a bite of food you take in a breath (the epiglotis opens to let air into the lungs), then you take a bite/swallow of food (the epiglottis quickly covers the trachea so food won't go the wrong way). Now you take a breath just before you swallow a drink (the epiglottis opens so air can go down the trachea & quickly closes to cover the trachea & the drink is directed to the stomach). The epiglottis is opening up & closing off pathways back-and-forth like crazy!
If you've ever accidently breathed in air when taking a drink of a liquid and began to choke or cough, you've experienced what happens when the liquid got past the epiglottis and into the trachea when it wasn't sopposed to. By trying to breathe in, the epiglottis thinks it should open for air but liquid enters instead, causing an immediate reaction from the body. Your coughing reaction is your body's way of saying to the liquid: 'Get out of there! That area is for air only, and its not where you belong!'
What else can I help you with?
If your nose is clogged why can you breathe through your mouth?
the throat is connected to the lungs directly. The nose is then connected to the throat. Hence the mouth can still breath when the nose is blocked.....remember when you drank lemonade and it fizzed back through your nose??
What organ do cassowaries use for breathing?
The Southern Cassowary (like all birds) has a pulmonary system where the lungs and the mouth are all connected.
Where does the human respiratory system start?
The respiratory system starts at the nose (and mouth) and ends at the alveoli in the lungs
What organs are in the nasal?
there are no organs in your nose but it is connected to your lungs
What organ carries air from your nose and mouth to your lungs?
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.
Where do deer get air?
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.
Where does air go after entering your nose and mouth?
After entering your nose and mouth, air travels down your windpipe (trachea) and into your lungs.
How does a tiger breath?
through its mouth and with its lungs...like we do. x
What system made of the nose, mouth and lungs?
It that circulatory system?
What organs are found in the nasal?
there are no organs in your nose but it is connected to your lungs
Does the mouth prepare air for the lungs?
Yes, both the mouth and nose help to moisten and warm air before it enters your lungs.
What connects to the trachea?
The trachea, or windpipe, is the bony tube that connects the nose and mouth to the lungs, and is an important part of the vertebrate respiratory system. hi so what is the trachea connected to
