What is the epithelium lining the trachea capable of?
Epithelial cells in the respiratory tract protect the aveoli from infection by secreting mucus that traps bacteria and other particles. Micro villi push the mucus back up towards the digestive system in something called a "mucus escalator".
In chronic smokers these epithelial cells actually change type, removing the mucus escalator function. This loss of function is the pathophysiology behind smokers cough, as they must cough up the mucus they produce.
What significance of the fact that the rings of the trachea are incomplete posteriorly?
The trachea, commonly called the windpipe, is the opening adjacent to the esophagus opening, that leads to the lungs. The cartilage rings are incomplete to allow proper collapsing, so that food can go down the right pipe.
Why do people have hairs on their trachea?
The hairs on the trachea are called Cilia and are for helping lifting up the mucus up the throat. Smoking can kill these hairs and they will have to swallow the mucus.=D
What is the name of branches of the trachea?
The branches of the trachea are called bronchi. The trachea divides into the left and right primary bronchi, which further branch into secondary (lobar) bronchi and then into tertiary (segmental) bronchi within the lungs. This branching network continues to divide into smaller bronchioles, which lead to the alveoli where gas exchange occurs.
Why does your trachea produce mucus?
That is because lungs have a very large space and also has the bronchi (which makes mucous). that is why when u breath and dust goes in you cough. This tries to throw the mucous up the throat and out the body. That is why sometimes when you are sick and u cough, you fill some kind of strain or burning inside your chest.
Is the passage of a tube through the mouth into the trachea to establish or maintain an open airway?
An Endo-Tracheal Tube (ET Tube, or ETT)
I think the actual term their looking for is Endotracheal intubation
The tubes into which the trachea divide to go into each lung?
The trachea branches off into two tubes going to each lung called the Bronchial Tubes.
[ The trachea is lined with a moist mucous-membrane layer composed of cells containing small hairlike projections called cilia. The cilia project into the channel (lumen) of the trachea to trap particles. There are also cells and ducts in the mucous membrane that secrete mucus droplets and water molecules. At the base of the mucous membrane there is a complex network of tissue composed of elastic and collagen fibres that aid in the expansion, contraction, and stability of the tracheal walls. Also in this layer there are numerous blood and lymphatic vessels; the blood vessels control cellular maintenance and heat exchange, while the lymphatic vessels remove the foreign particles collected by the wall's surface. Around the tracheal wall there is a series of 16 to 20 horseshoe-shaped cartilage rings. They encircle the front part of the trachea but are open where the trachea lies next to the esophagus. Here the free ends of the cartilage are connected by muscle bands. Since the cartilage is in individual rings, rather than one continuous sheath, the trachea can stretch and descend with the breathing movements. The cartilage bands are replaced with fibrous scar tissue in advanced age.
Muscle fibres run over and alongside the cartilage, as well as through the mucous membrane. They serve to narrow and shorten the passageway in breathing. They also may contract in cold weather and when smoke, dust, or chemical irritants are in the inhaled air. During coughing, which is a forced exhalation, the muscle bands connecting the free cartilage ends press inward so that the tracheal lumen is about one-sixth of its normal size. Air rushing through this narrow channel travels at high velocities and is thus able to dislodge foreign elements from the trachea.]
Why is it the trachea stay open at all times?
It remains open by the C shaped rings of cartilage that make up the walls of the trachea. It allows for constant air flow.
Explain why swallowed food does not usually enter the airway leading to the lungs?
when the food descends down the esophagus the epiglottis covers the opening to the airway preventing food from entering. A person will usually cough if food gets caught on the epiglottis to clear the airway again. strokes (or any disorder that could cause paralysis of the neck muscles) may cause paralysis of the muscles of the epiglottis, which would inhibit or interfere with the epiglottis from closing (of which could cause choking).
Yikes, no. It's a tube in the throat. You breathe through it. ---- As noted by the astute author of the answer above, the trachea is not a bone in the leg, it is commonly called the windpipe, or the "tube" through which air passes when we breathe. It is connected to the larynx (voicebox) in the neck and to the mainstem bronchi in the lungs.
The bone in the leg that starts with a 'T' is the tibia, and is commonly called the shinbone.
Is the trachea anterior to the spinal cord?
Yes, the trachea is anterior to (in front of) the spinal cord or, in other words, the spinal cord is posterior to (behind) the trachea.
ANS2:The previous answer is 90 degrees wrong.
The trachea is ventral to the spinal cord. Anterior means towards the head and posterior means towards the tail. Ventral is towards the belly and dorsal is towards the back.
What keeps food from entering your lungs?
The epiglottis is a flap of skin in the throat that covers the trachea (tube to your lungs) when you eat and the esophagus (tube to your digestive system) when you breathe. This keeps air from entering your stomach and food from entering your lungs. In addition, cilia and mucus line the trachea walls. They trap dust,bacteria and other bits and pieces that you don't want in your lungs.
Describe the structure of the trachea?
The trachea is lined by cartilage and divided into two branches. These two branches are called the bronchi. The left bronchus enters the left lung and the right bronchus enters the right lung. Each bronchus is further divided into around 25 smaller branches. These smaller divisions of bronchi are known as the bronchioles. The bronchioles carry air into thealveoli.
Where does the trachea bifurcate?
The Trachea is located below the Larynx, which is just under the Pharynx.
The trachea is located in the throat, Near the Larynx. The larynx protrudes in men, causing the Adam's Apple, I'm telling you that so you can get a feel of where the Trachea is.
The Trachea is a tube that comes off of your throat. The Trachea leads to your lungs and allows air to pass in and out of the body. It can be found about halfway between your stomach and the start of your esophagus. The trachea is located in the larynx. In the neck
What two tubes are divided by the trachea?
After air passes through the larynx, it enters your windpipe, or trachea. The trachea cleans the air again and channels it into the lungs through two large tubes called bronchi. The bronchi divide into smaller tubes and eventually lead to air sacs called alveoli. It is in the alveoli that oxygen moves into your blood and carbon dioxide moves out.
i dont no the trachea is located just below the pharynx. when we breath the air enters the pharynx, the trachea, the bronchus,the bionchioles, the alveolus and finally enters th lungs
so the trachea moves air into the bronchus.The trachea is made up of ring of cartillage which keep the trachea opened when we inspire and expire
What happens when swallowing food?
Firstly, you chew it in your mouth. Then, you swallow by pushing the chewed up food down your throat with your throat. Next, the food you just ate will go down your esophagus into your stomach. It will then get digested by your stomach acids and move on to the intestines. After that, it will keep on moving until it gets out of your body (umm... pooping).
When you eat you relax and enjoy your food. Also when you eat you move your mouth up and down so the food turns into little pieces. When your food turns little you swallow. You swallow by taking all your saliva and pass it down through your throut witch pushes anything in your mouth. YOUR WELCOME :)What would happen if the epigolttis did noe cover the trachea?
The throat has two passageways; one for air and one for food. If the epiglottis were to be removed it would cause tremendous problems. The air you breathe would travel to the stomach rather than the lungs; the lungs must have air in order for the body and the brain to survive. Secondly, the food you eat would travel to your lungs rather than to your stomach. This would cause obvious problems such as pneumonia and drowning of the lungs as well as no nourishment for the body and brain as no food would be entering the stomach. The epiglottis serves as a little trap; keeping food, liquids and air from entering places inside the body where they should not be, as well as helping to guide these same things to where they DO belong.
What is the part of the throat that contains the vocal cords?
The larynx is the part of the throat that contains the vocal cords. This area is commonly known as the voicebox.
Trachea is a common biological term for an airway through which respiratory air transport takes place in organisms. The cells that line the trachea have minuscule hairs, which collect any dust that you inhale, and prevent it from entering your lungs. It is then removed by coughing. To prevent food from entering your windpipe, it has a small flap of skin at the entrance (epiglottis). When you eat, this flap closes over your trachea to prevent food from entering. * Vertebrate trachea, in terrestrial vertebrates, such as birds and mammals, the trachea allows oxygen and carbon dioxide to move from the throat to the lungs * Invertebrate trachea, in terrestrial invertebrates, such as onychophorans and insects, tracheae conduct air from outside the organism directly to all internal tissues
What are the two branches of the trachea?
The wind pipe is called a trachea. It brings air from your mouth down into your lungs. It is a straight tube at the top that separates into two branches, one going into each lung. These are the left bronchus and right bronchus.
What is the function of a trachea?
The function of the trachea is the same in all terrestrial vertebrates. It provides an airway from the mouth to the bronchi.
