------------------------------
Hiccups are bursts of inspiratory (breathing in) activity. ... Most simple cases of hiccups come after eating or drinking too much or too quickly. The stomach, which is situated right below the diaphragm, becomes distended and irritates it. This will cause the diaphragm to contract, as it does when we breathe in.

Answer 4

a hiccup is a reflex. It happens when a sudden contraction of your diaphragm causes the muscles of your chest and abdomen to shake. Then, the glottis, or the part of your throat where your vocal cords are located, closes. This creates the noise of air expelled from your lungs, or the “hic” sound that feels involuntary with hiccups.
