Medical Definition of Trachea
Trachea is another name for windpipe, which is the tube that connects your larynx to your primary bronchi, just before your lungs. You can’t breathe without your trachea.
One may also ask, what is the medical term for windpipe quizlet? Trachea. windpipe; passageway of air from the larynx to the area of carina where it splits into the right and left bronchus. Bronchioles.
In this way, what is the trachea?
The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people. The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung.
What are the branches of the trachea?
The windpipe (trachea) is the largest airway. The trachea branches into two smaller airways: the left and right bronchi, which lead to the two lungs.
What is the function of trachea?
The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body’s airway and has the vital function of providing air flow to and from the lungs for respiration.
What is another word for bronchi?
Plural for either of two airways, which are primary branches of the trachea, leading directly into the lungs. bronchial tubes.
What are bronchi?
Bronchi are the main passageway into the lungs. The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
How many bronchi are there?
There are as many as 30,000 tiny bronchioles in each lung. They lead to the alveoli by way of alveolar ducts. Together, the trachea and the two primary bronchi are referred to as the bronchial tree. At the end of the bronchial tree lie the alveolar ducts, the alveolar sacs, and the alveoli.
What is the size of your lungs?
1,500 Miles of Airways Your lungs are one of the largest organs in your body. The surface area of both lungs is roughly the same size as a tennis court and the total length of the airways running through them is 1,500 miles.
What is the function of the epiglottis?
The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
What is another word for larynx?
larynx. The larynx, or “voice box,” is the cartilaginous structure at the top of the trachea, or “windpipe,” which is in your throat. The larynx contains the vocal cords.
What is at the end of the trachea?
It begins at the bottom of the larynx, and ends at the carina, the point where the trachea branches into left and right main bronchi. The trachea begins at the lower edge of the cricoid cartilage of the larynx, and ends at the carina, the point where the trachea branches into left and right main bronchi.
What are the diseases of the trachea?
Diseases of the trachea and airways are uncommon and diverse. We have a special interest in these conditions, including tracheal stenosis, tracheal and airway tumors, tracheoesophageal fistula, and tracheomalacia.
What happens if the trachea is damaged?
The mucosal lining of the trachea may also be injured by inhalation of hot gases or harmful fumes such as chlorine gas. This can lead to edema (swelling), necrosis (death of the tissue), scar formation, and ultimately stenosis. However, TBI due to inhalation, foreign body aspiration, and medical procedures is uncommon.
What causes inflammation of the trachea?
Causes. Bacterial tracheitis is a bacterial infection of the trachea and is capable of producing airway obstruction. In this condition there can be inflammation of the linings of the trachea. A condition called tracheo-bronchitis can be caused, when the mucous membrane of the trachea and bronchi swell.
Can you live without a trachea?
Thomas was born without a trachea — the cartilaginous tube through which we breathe. The condition is called tracheal agenesis, and it is extremely rare. Such a baby dies silently, having never drawn a breath. Only a few of these babies, and only because of extraordinary surgical interventions, have survived.
Is trachea an organ?
The trachea is an important structure within your respiratory system, which is the organ system that delivers oxygen to your bloodstream. The trachea is a rigid tube that conducts air from your larynx to your bronchi. The inner surface of your trachea is lined by a mucus membrane, which is itself covered with cilia.
What is distinguishable about the trachea?
belongs to the digestive system. The main difference between trachea and esophagus is that trachea is the major. bronchi or the windpipe of humans whereas esophagus is the food pipe, which connects the pharynx to the. stomach. The trachea transport air in and out of the lungs.
