what isthe connection between the heimlich maneuver and the development of human speech?

Question

please answer my question.>>>>>>>>>>>>>>>

Answer 1

There is no direct relationship. The Heimlich maneuver is a resuscitative measure used to dislodge a trapped bolus of food from the nasopharnyx or the epiglottis or the trachea. It is a stretch of the imagination for some one to swallow a big chunk of food, nearly strangle, have a friend do a Heimlich's for the victim to grunt. The only vague correlation is the expulsive force that would vibrate the vocal cords and that is very tenuous at best. At best guess, first animal noises were hisses, that were expulsive breaths, and then the resonance of the larynx and sinuses and the articulation of the tongue and later in higher animals the curvature of the lips, face and tongue. While your teacher may have a valid idea, I see none. The diaphragm located beneath the lungs is a sheet of muscle transecting the body and during the Heimlich's maneuver, we can a violent expulsion of breath and the piece of food is dislodged, but again including the diaphragm, the relationship is tenuous because the simple act of breathing in all mammals requires much the same and would not by itself evolve into speech....it is control of the diaphragm that allows us a variety of sounds, so the two are unrelated.

Answer 2

The biggest connection is the importance of the muscle known as the diaphram. When we use our diaphram to push air out forcefully, we are able to tighten and relax our vocal chords to produce speech. WIthout this muscle, speech is not possible. The Heimlich Manuever is also reliant on the diaphram muscle. When performing the Heimlich, you use a closed fist and open hand to push upwards and inwards on the diaphram to force air out through your throat to expel the blockage.

This is an easy one. If the world gets too hot, we've proven that we can survive it because the "Cradles of Civilization" were in hot, dry areas. If the world gets cold, then we've already proven that we can withstand ice ages, and that's without any "high" technology. If the world gets overpopulated, it will, out of necessity, balance itself out. I don't think we need to worry about surviving the next 100 years. The real question is how to we keep the next 100 years from becoming the next Dark Age.
