Air enters a frog through its nostrils and passes into the nasal cavity, where it is warmed and filtered. From there, it moves into the lungs, where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be expelled. After this exchange, carbon dioxide-rich air travels back through the lungs, up the trachea, and out through the nostrils during exhalation. Frogs can also absorb oxygen through their skin, which aids in respiration.
In a frog, the sequence of food passage begins when it swallows a bug, which then travels down the esophagus to the stomach. From the stomach, food moves into the small intestine, where digestion and nutrient absorption occur. Next, it passes into the large intestine, where water is absorbed and waste is formed. Finally, the remains are expelled through the cloaca.

A frog certainly can trap air in their throat. This is a necessary skill that the frog has developed as a creature that lives both in and out of water.
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

The Oropharynx is the common passage for food and air. Liquid, food, and air all pass through this passage.

Yes, the laryngopharynx is a common passage for both food and air. It serves as the transition point where the respiratory and digestive systems intersect, allowing for the passage of air to the trachea and food to the esophagus.
No, glass bottles with plastic caps are typically sealed tightly to prevent air passage. However, if the caps are not securely tightened, there may be minimal air passage.
