What is the advantage of the configuration of the Conchae and Meatuses?

The function of the conchae is to increase the surface area of the nasal cavity – this increases the amount of inspired air that can come into contact with the cavity walls. They also disrupt the fast, laminar flow of the air, making it slow and turbulent.

Similarly one may ask, what is the function of the nasal cavity?

The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body.

What is the function of the mucosa of the nasal cavity?

The thin walled veins on which the nasal mucosa rests function to warm air entering the respiratory passage. Due to the high concentration of blood vessels in the nasal cavity, changes in these blood vessels contribute to nasal congestion.

What is the function of the nasal meatus?

A nasal meatus is a nasal passage of the nasal cavity, of which there are three; the superior meatus, middle meatus and inferior meatus. These nasal meatuses are also known as meatus nasi superior, meatus nasi medius, and meatus nasi inferior.

What is the function of the pharynx in the respiratory system?

In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system. (The conducting zone also includes the nostrils of the nose, larynx, trachea, bronchi, and bronchioles, and their function is to filter, warm, and moisten air and conduct it into the lungs.)

Is the nasal cavity an organ?

The nose is the organ of smell, and serves in breathing and airway function. The nasal cavity lies between the base of the brain (skull base) and above the oral cavity and palate below. The nasal septum is made up of cartilage (quadrangular cartilage) towards the front of the nose, and bone towards the back.

What is the function of the nasal cavity?

The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body.

How many sinus cavities do we have?

There are a total of four pairs of sinus cavities. They are given their names in accordance to where they are located on the face. The sinuses are the ethmoid sinuses, frontal sinuses, maxillary sinuses, and Sinuses are paired air cavities/spaces (pockets) found in the cranial (head) bones.

What are the different sinus cavities?

Function. The presence of sinus cavities within the cranial bone (skull) is essential for the following reasons: Sinus cavities allow for voice resonance. They help filter and add moisture to any air that is inhaled through the nasal passages.

What is the nasal septum?

A deviated septum is a condition in which the nasal septum — the bone and cartilage that divide the nasal cavity of the nose in half — is significantly off center, or crooked, making breathing difficult. Most people have some sort of imbalance in the size of their breathing passages.

What drains into the middle meatus?

52-3 The main openings into the nasal meatuses are the posterior ethmoidal cells into the superior meatus, the anterior ethmoidal cells and frontal and maxillary sinuses into the middle meatus, and the nasolacrimal duct into the inferior meatus.

What is the main function of the nose?

The nose is the body’s primary organ of smell and also functions as part of the body’s respiratory system.

What is the use 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 gives rise to the alveolar sacs?

The respiratory bronchiole branches to form alveolar ducts. The main wall of the duct between alveoli contains smooth muscle. The terminal portion of the respiratory duct (atrium) gives rise to the alveolar sacs, composed of a variable number of alveoli that appear as small compartments opening into the alveolar sac.

Which region of pharynx is not lined by mucosa?

The nasopharynx is lined with ciliated respiratory epithelium with mucous goblet cells, while the oropharynx and laryngopharynx are lined by non-keratinized, squamous epithelium.

What is the nasopharynx lined with?

The two main types of epithelia lining the nasopharynx are stratified squamous (comprising approximately 60% of nasopharyngeal epithelium) and pseudostratified columnar respiratory epithelium containing ciliated cells, goblet cells and basal cells.

What is the function of the larynx?

Function of the Larynx. It allows air to be directed into the respiratory organs for gas exchange. The larynx is also the organ that is responsible for producing vocal sounds (phonation) and therefore it is commonly known as the voice box.

What is the function of the windpipe?

Trachea (Windpipe) The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body’s airway and has the vital function of providing air flow to and from the lungs for respiration.

What is the larynx and what does it do?

Voice box: The voice box, or larynx, is the portion of the respiratory (breathing) tract containing the vocal cords which produce sound. It is located between the pharynx and the trachea. The larynx, also called the voice box, is a 2-inch-long, tube-shaped organ in the neck.

What is the function of the vocal cords?

Briefly, the vocal folds are folds of tissue located in the larynx (voicebox) that have three important functions: To protect the airway from choking on material in the throat. To regulate the flow of air into our lungs. The production of sounds used for speech.

What is the structure and function of the larynx?

The cartilaginous skeleton refers to the cartilage structure in and around the trachea that contains the larynx, or houses the vocal folds, (which used to be called the ‘vocal cords’). It is comprised of the thyroid, cricoid, and arytenoid cartilages.

What is the function of the larynx in the respiratory system?

The respiratory system aids in breathing, also called pulmonary ventilation. In pulmonary ventilation, air is inhaled through the nasal and oral cavities (the nose and mouth). It moves through the pharynx, larynx, and trachea into the lungs.

What is the main function of the epiglottis?

The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
