Internal nares allow for the passage of air from the nose to the pharynx.
The superior opening into the larynx is called the glottis. It is formed by the vocal folds and is responsible for regulating the passage of air into the respiratory system.
Filtering out large impurities, warming the air and adding moisture to it.
A vacuole is a small cavity in the tissue of an organism containing air and fluids. Carbon dioxide is allowed to enter a leaf through vacuoles.
It subtly moves upward, since it is made of flexible tissue. However, the epiglottis is used in regards to the digestive system as it separates liquid from solid foods into the esophagus/trachea. Therefore the epiglottis only "moves" when he eats rather than when he inhales.
An intake air duct serves as a passage for supplying air to an engine, and includes a first intake air passage, a second intake air passage, an opening-and-closing valve, an interlocking member and a coiled spring. The opening-and-closing valve is disposed swingably in the second intake air passage so as to open and close the second intake air passage
