Why is the love heart shape the way it is even though the actual heart is nothing like it?

If you look at the human heart, then u look at the heart that people refer to as the love heart. who has created this and why this shape because it doesnt look anything similar to the real heart.
Answer
In all actuality a "love" heart, as you refer to it, is shaped like a regular heart only more symmetrical and puffed up. take a look at a picture of a hubloke heart for example. it does come to a peak at the bottom and although the upper chambers are disproportionate and not as prominently rounded as an illustrated heart, there is some similarity to the shape. granted a real heart is covered with an array of arteries, veins and capillaries but underneath that all it is "heart" shaped.
