 &nbsp; &nbsp; &nbsp; &nbsp; O coração DEVERIA ser apenas um órgão muscular, e segundo o estudos, oco que bombeia o sangue de forma que circule no corpo. Ocorre nos anelídeos, artrópodes, moluscos e cordados. A partir dos répteis crocodilianos surge o septo de sabatier', uma barreira física ventricular que impossibilita a mistura de sangue venoso com o arterial, dividindo o coração em duas cavidades, direita e esquerda, cada qual com outras duas cavidades, átrio e ventrículo, separadas por valvas, sendo tricúspide do lado direito e bicúspide, ou mitral, do lado esquerdo. Por esse motivo esses animais possuem circulação dupla e completa. Isso ainda não chegou completamente aos humanos. <!--[if gte mso 9]>     Normal   0         21         false   false   false      PT-BR   X-NONE   X-NONE                                                     MicrosoftInternetExplorer4                                                   <![endif]--><!--[if gte mso 9]>  <w:LatentStyles DefLockedState="false" DefUnhideWhenUsed="true"

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; As pessoas determinam-o como o CULPADO para emoções e sentimentos, sendo que o nosso cerebro que é realmente culpado! Mais se atendo somente a fatos, realmente, o Cerebro é quem determina emoções, fato inquestionável. Mas também é verdade que quando sentimos algo parecido com uma desilusão amorosa ou gostamos muito de alguém é no peito que isto se reflete. Talvez seja porque haja algum movimento específico de um conjunto de músculos que reagem sobre este estímulo, realmente não sei. Mais que para mim eles trabalham em conjunto, trabalham! Queria muito que apenas meu Cerebro sentisse aquela dorzinha no peito, de falta, saldade ou ate mesmo solidão. Seria tudo mais facil e tranquilo de lhe dar. Mais o que o coração representa nessas situações, é  inquestionável!(Cefeiro)
