What is the anatomy of the nasal cavity?
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.
How is the nasal cavity divided?
The nasal cavity is divided into left and right sides by a wall of cartilage and bone (called the nasal septum). Air moves through these passageways when you breathe. The nasal cavity is above the roof of the mouth (called the palate) and surrounded by the paranasal sinuses.
What are the structures and functions of the nasal cavity?
The nasal cavities are chambers of the internal nose. In front, the nostrils, or nares, create openings to the outside world. Air is inhaled through the nostrils and warmed as it moves further into the nasal cavities. Scroll-shaped bones, the nasal conchae, protrude and form spaces through which the air passes.
What is in the nasal cavity?
The nasal cavity lies above the bone that forms the roof of the mouth and curves down at the back to join the throat. It is divided into two sections called nasal passages. Air moves through these passages during breathing. The nasal passages filter and warm the air, and make it moist before it goes into the lungs.
What are 3 main functions of the nasal cavity?
There are three main functions of the nasal cavity which are: olfaction, respiration, and the role this part of the body plays in immunity.
What is the parts of the nose?
Nose Parts The nose has two holes called nostrils. The nostrils and the nasal passages are separated by a wall called the septum (say: SEP-tum). Deep inside your nose, close to your skull, your septum is made of very thin pieces of bone.
What are the primary function of the nasal cavity?
The nasal cavity is the inside of your nose. It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won’t get nosebleeds from a dry nose. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.
What is the nasal process?
Nasal processes The medial nasal process (nasomedial) on the inner side of each nasal pit merge into the intermaxillary segment and form the upper lip, crest, and tip of the nose. The lateral nasal process from each side merge to form the alae of the nose.
What is the main function of the nasal cavities?

What are the functions of nasal cavity?
The nasal cavity functions to humidify, warm, filter, and act as a conduit for inspired air, as well as protect the respiratory tract through the use of the mucociliary system. The nasal cavity also houses the receptors responsible for olfaction.
What divides the nasal cavity into two parts?
Together, these bones are referred to as the hard palate. A thin vertical plate, the nasal septum, divides the nasal cavity into two chambers (nasal fossae).
What are the special functions of the nasal cavity?
The nasal cavity has four functions: Warms and humidifies the inspired air. Removes and traps pathogens and particulate matter from the inspired air. Responsible for sense of smell. Drains and clears the paranasal sinuses and lacrimal ducts.
What structures are involved with the nasal cavity?
Structures of the olfactory system include: Nose: opening containing nasal passages that allows outside air to flow into the nasal cavity. Nasal cavity: cavity divided by the nasal septum into left and right passages. Olfactory epithelium: specialized type of epithelial tissue in nasal cavities that contains olfactory nerve cells and receptor nerve cells.
What is the role of the nasal cavity in the respiratory system?
The nasal cavity warms the air as it enters, acting as filtration and purifying the air by removing any dust, pollen, and other contaminants, before it passed to the inner body. Mouth. Also called the oral cavity, the mouth is the secondary exterior opening for the respiratory system.
