Not the head, the entire torso. Just elevating the head doesn't elevate the esophagus and won't help with the GERD (you'll also get a neck ache).
Basically, what helps is gravity, in a couple of different ways. First, with the esophagus elevated, the stomach acid doesn't stay in the esophagus for as long and can't do the same amount of damage and it's also less likely to come up in the first place. Second, the entire liquid mass of the abdomen isn't pressing on the stomach as much. This is especially true for pregnant women, many of whom have chronic heartburn during the 2nd and 3rd trimester. And last, there is a potential connection between GERD and sleep disordered breathing and while this may not have a causal relationship (they may both be due to a third or multiple issues, e.g., obesity), there is some speculation that one may cause the other. Also, breathing better during sleep has huge potential health benefits, so there's no downside even if it isn't related. Most specialists recommend at least 6"- 8" of elevation to have a positive effect although I tend to think that any amount that could be tolerated (if 6"-8" can't) would be a good idea. It's also possible to build up the elevation over time so that the sleeper can adapt ergonomically.
YesThe head is superior to the shoulders. The head is on top of the shoulders which is connected.
the head is superior to the thorax. the thorax is inferior to the head.
Head - Tail - Tail - Head
Your head is heaviest part of your body.
The removal of a person's head (or the head of any animal) is decapitation.(see the related question)
To prevent stomach contents from refluxing back into the esophagus.
DefinitionA reflux board is a device prescribed for use in children who have gastroesophageal reflux. The board tilts the child upward, to prevent or reduce gastroesophageal reflux while the child is lying in bed.InformationA reflux board is used to lift the child's head and shoulders above his stomach. It uses gravity to reduce episodes of gastroesophageal reflux, in which stomach contents flow out of the stomach, back into the esophagus and mouth, and possibly into the lungs. The board is used less often these days, because it has been replaced by new medical treatments and less invasive surgeries (using scopes).

Distal Esophagitis is inflammation of the esophagus. This can be caused by various reasons. Gastroesophageal reflux (GER), infection, trauma and food allergy. The affected portion of your esophagus is 5cm or about 2 inches. This inflammation results from gastric acid, pepsin, trypsin and bile are regurgitated into the esophagus. Symptomatic treatment for mild reflux is antacids, elevated head positioning when prone or sleeping and diet changes including changes to nighttime eating prior to sleeping.
You may have GERD (gastroesophageal reflux disease). In order to minimize symptoms, do not eat anything, or drink alcohol or caffeine, within 3 hours of bedtime. Raise the head of your bed (by putting 2-3 inch blocks under the headboard legs. Do not sleep on your back, but rather on your side. Check with your physician for any persistent symptoms.
it is the difference in elevation between head and tail water
Nope, they head lower in elevation to feed in winter.
About 540 feet above sea level.
Hydraulic head is related to the amount of energy present in a hydraulic system. Hydraulic head is composed of three components: elevation head, pressure head, and velocity head. As water loses one component of its hydraulic head, the other components increase. For example: water that falls 10 feet loses 10 feet of elevation head and gains 10 feet of velocity head. The only way a hydraulic system can lose hydraulic head is through head loss due to friction.
not recommended
The recommended water pressure is 0.5 to 1 bar
The base of diamond head is sea level. At least one portion of the cone rises to about 761 feet above sea level.
