New research has identified the mechanism by which air pollution damages the lungs’ self-cleaning system, leaving us ...

Air pollution is the second leading risk factor for death globally, with most of the world population subject to harmful air ...

Artificial cilia were tested by deploying them both independently and in conjunction with an airway stent inside artificial trachea and sheep trachea. The team explained that sensing signals were ...

When you inhale, air enters your body through your windpipe, or trachea, the tube that connects ... mucus and hair-like structures called cilia get rid of dust and dirt that come in with the ...

Robotic sensory cilia that monitor internal biomarkers to detect and assess ... the sensors either separately or together with an airway stent inside an artificial trachea and sheep trachea. The ...

Mechanical engineers have developed a system of artificial cilia capable of monitoring mucus ... with an airway stent within an artificial trachea and sheep trachea. Sensing signals are ...

In the former he found that the bronchial epithelium contained more goblet cells, shorter cilia and a thicker epithelium ... 22 From the trachea and bronchi of human beings (or animals) a cup ...

The trachea ends at a ridge of cartilage that separates and forms the junction into the bronchi (carina). Mucosal membranes are made up of epithelial cells, mucus-secreting goblet cells, and hair-like ...

These include direct or secondary effects on the mucus, mucus glands, the cilia, ciliated cells, blood flow and the smooth muscle of the trachea. Unfortunately, there is little information ...

These help the trachea to keep its shape and move easily during breathing. The inside wall of the trachea has tiny hairlike structures (cilia). This keeps out tiny pieces of dust, allowing clean air ...
