How does hiccups affect the respiratory system?

Answer 1

Mostly, it is due to the glottis. Your diaphragm contracts first causing an intake of air. The "glottis" (the vocal part of your larynx) closes and stops the air coming in. When that air hits the glottis, which is closed, it causes the sound that you are referring to as a hiccup.

Answer 2

An abrupt rush of air enters your lungs causing the epiglottis to close creating a "hic" sound.

Hiccups are commonly caused by damage or irritation to phenric and vagus nerves.

Answer 3

your nuts will fall off

Answer 2

Hiccups are a symptom of your diaphragm spasming - this could be because your breath caught, or because you swallowed something down the wrong way, though in this case you are more likely to choke. It will interrupt your breatjing periodically during these spasms since the diaphragm controls your breathing.
