The last structure the air will pass through will be External nares
<u>Explanation:</u>
The upper portion of the respiratory tract is the nasal cavity and the nose. The external nose forms the first and foremost respiratory tract area. Nose is the major part that is responsible in exchanging air with the atmosphere. It is responsible for the human survival.
There are two openings in a nose. These are called as nostrils. They are also called as exterior nares. The air from the atmosphere when inhaled it enters into the nostril. from there is is sent to the nasal cavity. Nasal cavity is the place where the air that is inhaled will be purified and it is transported to various human parts. thus, when air contains any dust or impurities it will make you to sneeze thereby the air gets out of the nose through External nares
Answer:
I think you're talking about how they survive in the snow. That would be by hibernating.
Explanation:
If you rephrase your question let me know and I can try to help you further :)
Extremes in temperature, pressure, and chemicals associated with injury are detected by specialized peripheral sensory neurons known as nociceptors, who then translate these stimuli into long-range electrical signals that are transmitted to higher brain centers. This alerts us to potentially harmful stimuli at the skin. A wide range of pain characteristics are produced by the activation of functionally different cutaneous nociceptor populations and the processing of the information they relay. Current research in this area is giving scientists a deeper understanding of the molecular and systems levels of nociceptor cell biology as well as knowledge that will enable the focused design of innovative pain treatments.
<h3>What is Chemical composition sense ?</h3>
Chemical senses (sometimes called chemical sensors) are sensory organs and neurological systems that are used to detect molecules in the environment or biological signals and to process those molecules neurally
