There are small particles in the air called aerosols. They are found in fog and smoke. These particles become larger in size if two processes occur. The first process is water vapor accumulating onto a particle. The next process is cool, rising air supporting the particle.…
Our journey begins with a molecule of rich oxygen. As we enter the nose, the oxygen makes its way through the nose hairs and into the nasal cavity. The nasal cavity is lined with mucous so there are no unwanted bacteria traveling with us. After floating a rough trip through the hairs and mucous, we make our way to the sinuses. These sinuses are air pockets in the skull; we’ll only be here for a little while.…
Ca2+ fluxes signal leukocyte recruitment to the lung and facilitate transepithelial migration into the airway lumen. Airway epithelial cells are situated well to play a crucial role in host response by providing a physical and an immunological barrier to inhaled pathogens. This physical barrier mediated by epithelial cell-to-cell junctions inhibits pathogens from invading, and the immunological barrier is attained through epithelial cell recognition of bacteria and swift signaling to recruit phagocytes and clear the infection. A central component in regulating the immunological and physical barriers of the airway epithelium is Ca2+.…

With that being said, the human body devised ways to inhibit this by the lungs secreting a sticky mucous layer throughout the airways that traps the particles and bacteria. The cilia of the lungs then recycle the mucous by moving it out of the airways and into the throat…
Treatments and Surgeries for Nasal Polyps What Are Nasal Polyps? Nasal polyps are noncancerous little polyps on the inside of the nasal cavity, where the sinuses open into the nasal cavity. Many people suffer from nasal polyps, especially individuals that battle with severe allergies and asthma. Mucus from sinus infections and asthma, irritate the polyps which can cause discomfort for many individuals.…
Continuous with the laryngopharynx, the superior portion of the larynx is lined with stratified squamous epithelium, transitioning into pseudostratified ciliated columnar epithelium that contains goblet cells. Similar to the nasal cavity and nasopharynx, this specialized epithelium produces mucus to trap debris and pathogens as they enter the trachea. The cilia beat the mucus upward towards the laryngopharynx, where it can be swallowed down the…
Respiratory Syncytial Virus – RSV Anatomical & Physiological Influences Causes RSV more frequently effects infants but can affect adults. Infants who have had RSV have an increase frequency of wheezing. Air enters the respiratory tract through the nose or mouth and then either enters the nasopharynx, or oropharynx respectively. Continuing through the laryngopharynx to trachea, which divides at the carina to form the left and right main bronchus.…
