Nov 9, 2022 · Turbinates, which are also called nasal concha or conchae (plural), are shell-shaped networks of bones, vessels, and tissue within the nasal passageways. These structures are responsible for warming, humidifying, and filtering the air we breathe.

Nasal decongestant reduces blood flow to the nasal turbinates, reducing tissue volume and increasing nasal airway patency. This study maps the changes in nasal anatomy and measures how these changes affect nasal resistance, flow partitioning between ...

Jul 13, 2021 · Turbulent flow requires more energy expenditure but results in better mixing, which contributes to nasal function. Turbulent flow can prevent clearance of air, which can cause a sensation of...

Jan 7, 2025 · Nasal turbinates are remarkable structures that enhance our breathing by warming, purifying, and humidifying the air we breathe. However, they can sometimes cause issues if they become enlarged or diseased.

Computational fluid dynamics (CFD) simulated nasal airflow in 22 healthy subjects during resting breathing. Streamline patterns, airflow distributions, velocity profiles, pressure, wall stress, turbulence, and vortical flow characteristics under quasi-steady state were analyzed.

May 27, 2020 · The actual exchange of energy and moisture takes place in the area of turbinates, but now in the direction from the air to the mucous membrane. For the expiration flow, the anterior cavum becomes a nozzle, which leads to a decrease in turbulence. With it, laminar flow can perfuse the narrowest opening, the ostium internum.

Sep 13, 2023 · The nasal conchae (also known as turbinates) are bony plates located on the lateral wall of the nasal cavity. There are three nasal conchae in each nasal cavity including the superior, middle and inferior nasal conchae.

Apr 17, 2015 · Each of the two narrow, curled, spongy bones protruding from the nasal cavity walls in the human nose is referred to as nasal concha or nasal turbinate. Covered in thick mucus membrane, the nasal conchae are responsible for regulating …

Nov 1, 2023 · Airflow turbulence enables maximum distribution of inspiratory air throughout the nasal cavities. During inspiration, the nasal mucosa releases heat and moisture to the inhaled air; during expiration, the opposite happens, allowing the partial recovery of heat and water and preventing fluid loss.

Jul 22, 2011 · Nasal turbinates partitions the airway of the nose into four air passages. Nasal turbinates force the inhaled air to course in a regular and steady pattern around cilia’s largest surface as well as the tissue that controls the climate.
