the Glottis.
The glottis is the hole that leads into the treachia.
The difference is that the second "frogs glottis" has a question mark.
The function of the pigs glottis is to produce sound. The glottis of the pig is surrounded by the epiglottis.
The slitlike passageway between the vocal cords is the glottis.
the glottis is the breathing and vocal pipe.
the glottis in the frog lets the frog breathe, the act kind of like lungs to breathe. by connecting to the lungs The glottis of a frog is an opening in the trachea. This opening allows for the frog to ingest air with his mouth closed, as well as for making their signature sounds
To produce deep tones the glottis widens.
The function of the epiglottis ( piece of cartilage) is to close the glottis ( trachea) when swallowing to prevent food from going down the wind pipe.
The glottis opens into the windpipe and is responsible for the production of sound. While the epiglottis is a cartilaginous flap on top of the glottis that prevents the food from entering the larynx. The main difference between glottis and epiglottis is their function and structure.
i believe the answer you're looking for is the trachea. correction; It is the Rima glottidis
epiglottis is the part of glottis which close over the trachea when we eat food because the food don't swelled in the trachea which is the wind pipe and go into the lungs.
