Epiglottis
when a doctor listens to the chest with a stethoscope during the Valsalva maneuver, characteristic heart sounds are heard. Variations in these sounds can indicate the type of abnormality present in the heart.
During this maneuver, a person performs the "breathe-in-bear-down" movement that is automatically performed during strenuous exercise
Valsalva maneuver Intra-abdominal pressure Compressive forces from muscle contractions Elevated cardiac output External compressive forces
less formally, the patient may be asked to bear down, as if having a bowel movement. During this 30 second period, a recording is made of the changes in blood pressure and murmurs of the heart.

Epiglottis
Sweating during a bowel movement can be a result of the Valsalva maneuver, where straining to pass stool can increase pressure inside your abdomen, triggering sweating as a response to the physical exertion. Additionally, the warm and confined space of a bathroom may also contribute to sweating during a bowel movement.

epiglottis
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.
