"What the traditional "heart shape" actually depicts is a matter of some controversy. It only vaguely resembles the human heart. Some people claim that it actually depicts the heart of a cow, a more readily available sight to most people in past centuries than an actual human heart. However, while beef hearts are more similar to the iconic heart shape, the resemblance is still slight. The shape does resemble that of the three-chambered heart of the turtle, and that of the human male prostate gland, but it is very unlikely that the image was patterned after either of these organs.

Ancient silver coin from Cyrene depicting a silphium seed or fruit.The "heart" shape could also be considered to depict features of the human female body, such as the female's pubic mound or vulva. A Sumerian cuneiform symbol for "woman" closely resembles the heart shape, and is believed to directly depict the pubic mound. Others maintain that the heart resembles the shape of the female breasts or the female buttocks.

Another possible origin can be seen on the coins of the ancient city of Cyrene, some of which depict the seeds or fruit of the now-extinct silphium plant. The seeds are distinctly heart-shaped. Since this plant was widely used as an ancient herbal contraceptive or abortifacient, this shape may have come to be associated with sexuality and love."

Answer 2

From your description of the question, it looks like you should have asked, "Why the heart shape NOT a heart shape?". Rephrasing it, "Why the typical heart shape is drawn the way it is, when the real heart does not resemble it in shape?"
What can we say? Let's assume it is a close approximation to the real heart. Just imagine how would it look like on a Valentine's card if we had to draw the REAL heart, with its four chambers and aorta and vessels perhaps?

Answer 3

When one looks at the place where the heart is, and usually the subject of stares is the female bosom, an image of the heart is formed with the crus down below. It is not difficult to imagine that you refer to an organ in the chest when you show a heart-shape.

Answer 4

Because thats the TRUE shape of a heart. You see theres this door called LSD. When you open that door, you see the world RAW. No filters of the mind, no restrictions of the brain, and everything is real and possible. You'll see if you open that door.
