describe the role of vehicles and epithelium in the nasal passage
Answers
Answer:
Nasal passage: A channel for airflow through the nose. The walls of the nasal passages are coated with respiratory mucous membranes, which contain innumerable tiny hair-like cells that move waves of mucus toward the throat.
Explanation:
The nasal cavity refers to the interior of the nose, or the structure which opens exteriorly at the nostrils. It is the entry point for inspired air and the first of a series of structures which form the respiratory system. The cavity is entirely lined by the nasal mucosa, one of the anatomical structures (others include skin, body encasements like the skull and non-nasal mucosa such as those of the vagina and bowel) which form the physical barriers of the body’s immune system. These barriers provide mechanical protection from the invasion of infectious and allergenic pathogens.

Anatomy of the nasal cavity
The nasal cavity extends from the external opening, the nostrils, to the pharynx (the upper section of the throat), where it joins the remainder of the respiratory system. It is separated down the middle by the nasal septum, a piece of cartilage which shapes and separates the nostrils. Each nostril can be further divided into roof, floor, and walls. The nasal cavity can be divided into the vestibule, respiratory and olfactory sections.
Nasal vestibule
The nasal vestibule is the dilated area at the nostril opening.
Respiratory section
The respiratory section of the nasal cavity refers to the passages through which air travels into the respiratory system. The respiratory section of each nostril contains four conchae (protrusions or bumps) which are also referred to as turbinate bones or lobes and are covered by the nasal mucosa. Underlying these conchae are meatuses (passages to interior body structures). The meatuses of the nasal cavity connect to the paranasal sinuses.
Olfactory region
The olfactory receptors (receptors for smell sensations) are found in this section of the nasal cavity. Bowman’s glands are also found in this section of the nasal cavity.
Surrounding structures
Para-nasal sinuses
The nasal cavity is surrounded by a ring of paranasal sinuses and meatuses in the nasal cavity connect to these structures. The sinuses develop as outgrowths of, and drain into, the nasal cavity. The mucosa of the sinuses connects to the nasal mucosa.

The nasal cavity refers to the interior of the nose, or the structure which opens exteriorly at the nostrils. It is the entry point for inspired air and the first of a series of structures which form the respiratory system. The cavity is entirely lined by the nasal mucosa, one of the anatomical structures (others include skin, body encasements like the skull and non-nasal mucosa such as those of the vagina and bowel) which form the physical barriers of the body’s immune system. These barriers provide mechanical protection from the invasion of infectious and allergenic pathogens.
