What goes in and out of the external nares?
Mostly air .
What are the functions of a fetal pig's external nares?
The paired nares are another term for the nasal openings on a pig. These nares take in air to the sinuses.
Function of external nares on frogs?
For the most part, frogs breathe air through the mouth, and utilize internal nares when doing so outside of the water. In the water, they can put just enough of the external nares above water, but this is more important to get rid of carbon dioxide, as frogs can diffuse oxygen from the water through their skin.
What is the function of internal nares?
Internal nares allow for the passage of air from the nose to the pharynx.
These feathers filter air that enters the nostrils of a bird?
Very few species of bird actually have feathers covering the nares, or external nostrils. Of these, the woodpecker's the one who needs it to filter the air, specifically from wood particles.

What are the functions of a fetal pig's external nares?
The paired nares are another term for the nasal openings on a pig. These nares take in air to the sinuses.
Where are internal nares?
Nares are the openings of the nasal cavity, commonly called nostrils. We have two sets of openings called anterior and posterior nares that move air through the nasal cavity into the pharynx and lungs.
Function of external nares on frogs?
For the most part, frogs breathe air through the mouth, and utilize internal nares when doing so outside of the water. In the water, they can put just enough of the external nares above water, but this is more important to get rid of carbon dioxide, as frogs can diffuse oxygen from the water through their skin.
Why is the tip of the nose an ideal location for the external nares?
The location is best for respiration. The air is not restricted to a curved or misshapen pathway that causes delays in air being drawn into the lungs.
What is the function of internal nares?
Internal nares allow for the passage of air from the nose to the pharynx.
What is the singular form of the word alveoli?
One alveolus is a singular, tiny air sac of the lung, surrounded by a network of capillaries, and through which oxygen and carbon dioxide are exchanged. A cluster of such air sacs are alveoli (plural of alveolus).
What fills the space inside an alveolus?
Air.

Very few species of bird actually have feathers covering the nares, or external nostrils. Of these, the woodpecker's the one who needs it to filter the air, specifically from wood particles.
Where are the external nares on the frogs located?
The internal nostril openings (nares) carry air from the nostrils to the mouth, so that a frog can breathe air when on the surface, by expanding its mouth to pull in and "swallow" air. Underwater, the internal nares close to keep water out.
Explain how it is possible for a person to drink liquid and then have the liquid come out through the nose when the person laughs?
The oropharynx is connected to the nasopharynx via the internal nares. When the mouth is closed, air from the laryngopharynx forces food or liquid from the mouth up through these passageways into the nasal cavity and out the external nares. -
