Nasal cavity in the upper respiratory tract.
True. As air moves through the mouth and nasal passages, it is warmed and moistened by the respiratory mucosa lining these passages before reaching the lungs. This helps to protect the lungs and optimize the exchange of oxygen and carbon dioxide.
The part of the food tube where the gastrointestinal (GI) tract and the respiratory tract cross each other is called the pharynx. This is a crucial junction where the passages for food and air intersect before they continue on to the esophagus and the trachea, respectively.
The air is warmed and moistened in the respiratory system by passing through the nasal cavity, where it comes into contact with mucus and blood vessels. The mucus helps to humidify and warm the air before it reaches the lungs, creating an optimal environment for gas exchange.
the nose belongs to the respiratory system.
Nasal cavity in the upper respiratory tract.
The respiratory system of the red fox, like that of other mammals, consists of the nasal passages, trachea, bronchi, and lungs. Air is inhaled through the nasal passages, where it is warmed and filtered before passing through the trachea and branching into the bronchi, which lead to the lungs. In the lungs, oxygen is exchanged for carbon dioxide in the alveoli, and the oxygenated blood is then circulated throughout the body. The red fox's respiratory system is adapted for efficient gas exchange, supporting its active lifestyle as a hunter.

The nose is the organ of smell, part of the of respiratory system, and it adds nasal sounds to the voice. Air passes through a lining of stiff hairs that catch dust particles and small insects before entering the nasal passages where it is warmed and moisturized before passing into the respiratory system on its way to the lungs. The olfactory nerve (nerve of smell), is located in the soft mucous membrane inside the nose.
The upper respiratory system employs several mechanisms to filter out dust and bacteria before they reach the lower respiratory system. Cilia, tiny hair-like structures lining the nasal passages and trachea, sweep mucus and trapped particles upward toward the throat, where they can be swallowed or expelled. Additionally, mucus traps dust, pathogens, and other debris, preventing them from entering the lungs. The rich blood supply in the upper respiratory system also helps warm and humidify the air, further protecting the delicate tissues of the lower respiratory system.

A cold is a mild viral infection involving the nose and respiratory passages (but not the lungs) and sinus infection or sinusitus is Inflammation of one of the paranasal sinuses.
Yes, the nose tends to be more moist in low altitudes because the air is usually more humid closer to the ground. This humidity helps keep the nasal passages moist and aids in trapping particles before they enter the respiratory system.
Two structures that help trap dust and smoke before they enter the respiratory system are the nasal hairs and the mucous membranes. Nasal hairs, or vibrissae, filter larger particles from the air, while the mucous membranes lining the nasal passages produce mucus that traps smaller particles and pathogens. Together, these structures play a crucial role in protecting the lungs from irritants and contaminants.
Air moves through the nostrils to be filtered, moistened, and warmed before entering the respiratory system. The fine hairs and mucus in the nostrils trap dust and particles, while the blood vessels in the nasal passages help to warm and humidify the air. This process helps to protect the delicate tissues of the respiratory system from damage.
