What makes up the lower respiratory system? How does the respiratory system provide oxygen to the body? Describe the structure and function of the respiratory system. How does the respiratory system affect other body systems? What keeps the respiratory system healthy?
Acid reflux can also play a role. Acids can travel up from the stomach into your throat and all the way to your larynx. This may irritate your larynx and make you lose your voice. Rarely, chronic laryngitis is caused by infection by bacteria, viruses, or parasites. Some health conditions...

LPR (laryngopharyngeal reflux) is acid reflux that comes up into the larynx (voice box) and pharynx (throat). I coined the term in 1987 to distinguish what I was seeing in my patients with voice, throat, and respiratory problems from GI patients with heartburn and esophageal disease (GERD)...
The larynx is lower in the throats of humans than it is in chimpanzees, which, along with the increased flexibility of the mouth, tongue, and lips, is what enables humans to speak as well as to change pitch and sing. The ability to speak and develop language was an enormous advantage ...

Bats make echolocating sounds in their larynxes and emit them through their mouths. Fortunately, most are too high-pitched for humans to hear – some bats can scream at up to 140 decibels, as loud as a jet engine 30m away. Greater horseshoe bat using echolocation to chase a moth. © ...
Crocodilians, just like humans, have a larynx, and make sounds byvibrating their vocal cords. Yet the exact mechanism for crocodile noises has, until recently, been a bit of a mystery. One study investigated alligator sound production by looking at the larynx anatomy. The authors found that al...
Your child's voice will change around the time that their growth spurt has begun to slow down a bit. This occurs because their vocal cords and voice box (larynx) gain mass, too. Before their voice changes completely, it may crack and soar, going from high to low quickly.10This can be...
