The point of distillation (of alcohol) is to separate the ethanol from the other undesired components. The distillation process takes advantage of the different volatilities. In the fermented MASH are undesired substances more volatile than ethanol (e.g. methanol) which will distill out first. This is the Heads and is discarded. Once these more volatile compounds are eliminated you have the Heart of the run which is the quality product. Finally if you keep distilling you begin getting some undesirable lower volatility substances, oils and water, the Tails, which is also discarded by stopping the distillation run. The art of the experienced distiller is to know when to draw the lines between Head, Heart, and Tail. The more selective one is, the higher quality (but less quantity) of the produced distillate.

There is a steam distillation but no sloping splash head?
This is the top of a distillation installation.
If a flask is not well secured to the head, all the gas will run out of the distiller.
Head - Tail - Tail - Head
A and B is a vector by replacing the tail of the B on the head of the A and the join the tail of the A with the head of the B this method is called head to tail rule
Type, 'Steam Distillation Sloping Splash-head' into Google and hey presto, lot's of links.

A shrimps heart is located on its head. If we base it on the exact anatomy of a shrimp, its heart is located on its thorax just after the head, but both the head and the thorax are covered with a single exoskeleton only, that is why the shrimps thorax can be mistaken as still part of the shrimps head. But in general, we see a shrimp divided only into 2 parts, the head and the tail, we see no thorax in it.
