Respiratory infections are common illnesses. Children are especially likely to get them. They can affect your upper or lower respiratory tract. Upper respiratory infections include: The common cold Epiglottitis, a swelling of the top part of the trachea that sits at the back of your throat Laryngi...
Phonation is the creation of sound by structures in the upper respiratory tract of the respiratory system. During exhalation, air passes from the lungs through the larynx, or “voice box.” When we speak, muscles in the larynx move the arytenoid cartilages. The arytenoid cartilages push the...

Recent epidemiologic investigations have pointed to an increase susceptibility of obese individuals to lower respiratory tract infections. The cellular mechanism responsible for this phenomenon has not been identified. To assess whether obesity per se impairs the proinflammatory and antimicrobial functions of ...

Type III IFNs are important for controlling viral infection in the upper respiratory tract, whereas there is more functional redundancy between type I and III IFNs in the lower respiratory tract (Klinkhammer et al., 2018). Bone marrow chimera and conditional knockout experiments reveal that IFN...
Thetracheais the part of the respiratory tract that leads from the larynx and ends lower down in the thoracic cavity where it divides into the two main bronchi (left and right). It lies almost exactly in the middle of the neck (median) although in most healthy people, it may be noticed...
