What is the structure of nasal cavity?

Answer 1

Within the nasal cavity are structures called Conchae or Turbinates. These structure cause the air being inhaled to spin and warm up as well humidifying it so that it doesn't damage the lungs when it gets there.

Answer 2

The structure of the nasal cavity is complex, considering the relatively simple sensory role of the nose.

The nasal cavity is comprised of a superficial layer of epithelium. The nasal vestibules (nostrils) are lined with sebaceous and sweat glands, as well of hair.

There are right and left halves of the nasal cavity. The nasal septum divides these right and left halves. There is an anterior region and a posterior region of the nasal septum. The anterior region is made up of hyaline cartilage, and the posterior region is made up of the vomer and ethmoid bones.

In both the right and left halves, there are lateral (side) walls. Each of the walls has 3 bones: the superior concha, the middle concha, and the inferior concha. Below each of these concha is a space called the meati. There is one meati named for each. The middle and superior conchae are covered with olfactory epithelium, and the inferior conchae are covered with respiratory epithelium.

The lateral (side) walls have 2 primary openings. The first opening is the nasolacrimal ducts, which carries tears from lacrimal sacs to the nasal cavity. The second opening is the paranasal duct, which is where the paranasal sinuses drain. Both of these ducts are lined with mucous membrane.

Answer 3

Air that enters through your nostrils then moves into the nasal cavity

Answer 4

Nasal cavity musosa is the lining of the inside of the nose.

Answer 5

The nose cavity is part of the sinus cavity. The sinuses are in the upper respiratory tract.

Answer 6

These function to draw air into the respiratory tract, to filter the air of dirt and small insects and to warm it.

Answer 7

The nasal cavity is lined with mucous membranes. These membranes moisten, warm, and filter incoming air.
