An embryo needs oxygen for cellular respiration, glucose for energy, and essential amino acids for protein synthesis in order to grow and develop properly.
The first organ to develop in the embryo is the heart. It starts to form and beat as early as 3 weeks after conception.
The heart is the first organ to form in a human embryo. It begins to develop and beat as early as week 3 of gestation.
The developmental stages of an embryo include the pre-embryonic stage (fertilization to week 2), embryonic stage (weeks 3-8), and fetal stage (week 9 to birth). During the embryonic stage, major organs and structures begin to form, while during the fetal stage, these structures continue to grow and develop in preparation for birth.
During week one, the embryo is still at the stage of implantation and does not have a measurable length. By the end of week ten, the embryo has developed into a fetus and is typically around 1.2 to 1.6 inches (3 to 4 centimeters) long.
