An embryo is the early stage of a baby’s development during pregnancy. The first stage is the fertilized egg ( zygote ). It divides to become a blastocyst and travels down the fallopian tube to the uterus, where it may implant to establish the pregnancy. The developing baby is termed an embryo from week five until the end of the 10th week of ...Development begins at the moment of conception, when the sperm from the father merges with the egg from the mother. Within a span of 9 months, development progresses from a single cell into a zygote and then into an embryo and fetus. The fetus is connected to the mother through the umbilical cord and the placenta, which allow the fetus and ...

The intricate processes of fetal development, from conception to birth, lay the foundation for a healthy and successful ... The placenta is the largest fetal organ, and toward the end of pregnancy the umbilical circulation receives at least 40% of the biventricular cardiac output. It is not surprising, therefore, that there are likely to be close haemodynamic links between the development of the placenta and the fetal heart. Development of the placenta is precocious, and in advance of that of the fetus. The ... This review article describes key cardiac progenitors involved in embryonic heart development; the cellular, physiological, and anatomical changes during the transition from fetal to neonatal circulation; as well as the unique impact that different pregnancy complications have on cardiac remodeling. The embryonic stage of gestation is the period after implantation, during which all major organs and structures within the growing mammal are formed. Once the embryo is fully formed, it expands, grows and continues to develop into what is known as the stage of fetal development. This is when the mother becomes physically and visibly pregnant. Human embryonic development, or human embryogenesis, is the development and formation of the human embryo.
