What else can I help you with?
What is epiglottis and what is its purpose?
It's a "flap" that covers either the trachea or esophagus. It prevents you from choking. When you eat, it covers the trachea so food will go down the esophagus and not the windpipe (trachea). If food gets down your trachea, you will choke.
What happens to the shape of trachea when swallowing food?
It is important that food not go down the trachea, or expand the esophagus into the trachea or larynx. The epiglottis blocks the trachea when swallowing, and the change in shape makes this more effective.
Does Peristalsis within the trachea help push food to the stomach?
No, peristalsis is the wavelike muscular contractions that help move food through the esophagus and into the stomach. The trachea is the airway that leads to the lungs, and peristalsis does not occur in the trachea to push food to the stomach.
Trachea allows air to draw into the lungs?
yes you have a esophagus for when you eat food that has muscles that pushes food down to your stomach, that's why you can swallow even if your upside down and you have a trachea for air.
Passageway for food that is behind the trachea?
The passageway for food that is behind the trachea is the esophagus. After swallowing, food travels down the esophagus to reach the stomach for digestion, while air goes down the trachea to enter the lungs for respiration.
Whats the pathway called air and food go down?
Food goes down the esophogaus and air goes down the trachea.
What is the different between windpipe and gullet?
The windpipe is the pipe in which air and gasses travel down (i.e oxygen) the gullet is the pipe which our food and drink travel down
What does it mean when someone says food went down the wrong tube what?
The food went down the trachea, the one that leads to the lungs
What does the epiglottis do?
So food or water will not enter into your windpipe and breathing system (lungs). The food and water then avoid going down the windpipe because of this flap - the epiglottis and go into the digestive track - down the esophagus.
What happens to the shape of the trachea when you swallow a large mouthful of food?
The trachea is supported by C-shaped rings of cartilage. The point at which there is no cartilage is where the trachea is in contact with the oesophagus. As a large bolus of food passes down the oesophagus the elastic walls expand to accommodate it. This is made possible by the absence of cartilage on the trachea. However, the trachea is prevented from collapsing due to the supporting cartilage around the rest of it.
What muscular tube passes behind the trachea?
The muscular tube that passes behind the trachea is the esophagus. It serves as the conduit for food and liquids to travel from the throat to the stomach. The esophagus is situated posterior to the trachea and extends down the neck and into the thoracic cavity. Its muscular walls facilitate the movement of ingested materials through peristaltic contractions.
What prevents food entering trachea when swallowing?
The epiglottis is a flap of tissue located in the throat that covers the trachea during swallowing, preventing food from entering. Additionally, the muscles in the throat contract to push the food down the esophagus towards the stomach, instead of allowing it to enter the trachea.
