What does your trachea do?

Your trachea closes off your lungs when you swallow anything, so the food or liquid does not enter into your lungs and kill you.\nI hate when it doesn't work and i choke on water...gag

The vocal cords are two bands or folds of mucuous covered, elastic muscle tissue. They are located side by side in the voice box (LARNNX) When we are silent, the cords remain open. This is the airway throught which we breathe. \nSound is created when air fro the lungs is pushed throught the closed vocal cords causing them to vibrate - faster for higer sounds and slower for lower pitched sounds.\n\nThe sound quality of the voice is the result of the vocal cords opening and closing smoothly. If air manages to pass throught your vocal cords when it's not supposed to, the voice will sound raspy, hoarse, lower or higher than usual. \nThere are several reasons why a person can lose their voice. The vocal cords are subject to infections (laryngitis), Irritations (repetive strain or use of unhealthy substances like tabacco and alcohol), trauma (a blow to the larynx) and tumours (nodules, polps and ulcers).

Mine does that too...don't know why we do it...maybe to close off our mouth as an airway?

Respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. In the chest cavity, the trachea splits into two smaller tubes called the bronchi. Each bronchus then divides again forming the bronchial tubes. The bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. The average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale. \n\nThe diaphragm's job is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. As the diaphragm contracts and relaxes, breathing takes place. When the diaphragm contracts, oxygen is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs. \n\nThese links should help.

Your body absorbs the vapour like a sponge...:D

the tube in your ear.

It is your uvula, & that is spelled right...not sure what it is for though! Maybe as a baffle so food doesn't go down your windpipe so easily??

What Is Asthma? \n\nAsthma (Az-muh) is a chronic disease that affects your airways. The airways are the tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways are inflamed (swollen). The inflammation (IN-fla-MAY-shun) makes the airways very sensitive, and they tend to react strongly to things that you are allergic to or find irritating. When the airways react, they get narrower, and less air flows through to your lung tissue. This causes symptoms like wheezing (a whistling sound when you breathe), coughing, chest tightness, and trouble breathing, especially at night and in the early morning. \n\nAsthma cannot be cured, but most people with asthma can control it so that they have few and infrequent symptoms and can live active lives. \n\nWhen your asthma symptoms become worse than usual, it is called an asthma episode or attack. During an asthma attack, muscles around the airways tighten up, making the airways narrower so less air flows through. Inflammation increases, and the airways become more swollen and even narrower. Cells in the airways may also make more mucus than usual. This extra mucus also narrows the airways. These changes make it harder to breathe.

Respiration is performed using tracheae, air-filled tubes which open at the surfaces of the thorax and abdomen through pairs of spiracles. The spiracle valves only open to allow oxygen and carbon dioxide exchange. The tracheoles, found at the end of the tracheal tubes, are insinuated between cells and carry oxygen throughout the body. \n\nI hope this helps.

It is mucus in the back of your throat, normally when you have a cold. It traps some of the germs in your body.

The throat of a venturi is specially designed to accelerate a fluid, either a gas or a liquid. As the fluid accelerates, it gains kinetic energy. Due to the first law of thermodynamics, this energy must come from somewhere.\nIt comes at the expense of the pressure energy, i.e. when the kinetic energy increases, the pressure energy (and hence the pressure) falls.\nThe venturi has another inlet to the throat, which can be attached to something else where you want to apply your suction

There are specialized cells (goblet cells) that line all of the mucous membranes of your body: nasal passages, throat, lungs, intestines, urinary tract, eyes, vagina and etc.  These cells are capable of producing and excreting copious amounts of mucus in response to infections, allergies, injuries, stimulation, and  nflammation. Most of the time this mucus you make is  your body's way of protecting and/or healing itself.  Mucus production also helps us rid ourselves of foreign invaders (bacteria, viruses, pollen, dust etc.).  In the case of a cold, plugging up the nose with mucus may help to kill the viruses by blocking the natural "air conditioning" and raising the temperature of the nasal membranes.\n\nMucus is mostly made up of water, proteins and inorganic salts.  Stuff that is readily available to your body, so it is no problem to make plenty.

When it goes and touches the wind pipe the epiglottis closes the wind pipe preventing the fluid going inside the wind pipe.  The cough is the natural  and defensive phenomena which brings out the minute amounts  what is gone inside.

Nose/Mouth then Pharynx, Trachea, Bronchus, Alveoli,and then reverse for exhalation. 10 marks please, yippee ki yay!

Trachea divides into bronchi, Bronchi divides into bronchioles and then inte alveoli. Alveoloi are called the air-sacs and they are involved in the air respiration process.\nSo the smallest branch of bronchi are the alveoli(plural)and alveolus(singular).

I believe in general that coughs help rid your body of germs or other things that may have made their way into your airway.  Coughing is also common when there is a lot of drainage from nasal congestion hitting back of the throat (especially after taking decongestants).
