O embrião é um estágio inicial de desenvolvimento dos animais. Nos humanos, o embrião começa a se desenvolver cerca de quatro dias após a fertilização do óvulo.  Nos primeiros dias de existência do embrião, ele viaja ao longo da trompa de Falópio. . #biologia #enem #saude #biology #bebe

O que acontece nas primeiras semanas após a fertilização? 🧬✨ Desde o momento em que o espermatozoide encontra o óvulo, uma jornada extraordinária começa. Em poucos dias, o embrião viaja até o útero e se implanta na parede uterina, iniciando o desenvolvimento de uma nova vida. ✔️ O embrião se fixa no útero poucos dias após a fecundação. ✔️ O corpo começa a produzir hCG, conhecido como o hormônio da gravidez. #gravidez #gestaçao #desenvolvimentofetal #maternidade #gestante
