They connect the nostrils to the mouth. Air is drawn into the internal nares from the external nares, then passing through the mouth, through the trachea to the lungs. Eustachian tubes – connects to the middle ear. They are responsible for equalizing air pressure in the head.
Do humans have eustachian tubes?
Eustachian tube, also called auditory tube, hollow structure that extends from the middle ear to the pharynx (throat). The eustachian tube is about 31–38 mm (1.2–1.5 inches) long in humans and lined with mucous membrane.
Do Frogs have an inner ear?
Frogs do not have external ears like us. However, they do have eardrums and an inner ear. The frog ear is called a tympanum and is the circle you see behind a frog’s eye. The lungs vibrate and are almost as sensitive to hearing as the eardrum.
What is another name for the eustachian tube?
Overview. The eustachian tube (pharyngotympanic tube) connects the middle ear cavity with the nasopharynx.
What is the main function of the Eustachian tube?
This air-containing space is maintained by the Eustachian tube, which opens intermittently to equalize the intratympanic air pressure with the pressure in the external auditory canal. It also removes secretion and epithelial debris from the middle ear by ciliary motion and gravity.
What is special about frog skin?
Many frogs even have a special drink patch on the underside of the body. Like a giant lung, the thin, moist skin allows gases to pass through, helping the frog to breathe. To keep the skin working well, frogs must stay clean and moist. They produce sticky mucus to prevent drying.
Can we breathe out air through Eustachian tube?
So the correct answer is ‘One can breathe out air through the eustachian tube by closing both the nose and the mouth’. Note: Exhalation of the air by the powerful closure of mouth and nose prompts the air going through the Eustachian tube bringing about air circulation of the middle ear cavity.

Blocked eustachian tubes often get better on their own. You may be able to open the blocked tubes with a simple exercise. Close your mouth, hold your nose, and gently blow as if you are blowing your nose. Yawning and chewing gum also may help.

Are frogs deaf?
As in many other frogs, males produce calls to defend their territories and attract females. However, this species is a so-called “earless” frog lacking an external tympanum and is thus anatomically deaf.
