none what so ever :D
After a sperm fertilizes an egg its referred to as a zygote. Then it becomes a fetus, I believe after the first trimester.
the organs grow larger
An embryo is the early stage of development of a baby, typically from fertilization until about 8 weeks. During pregnancy, the embryo grows and develops into a fetus through a process called embryogenesis. This involves the formation of major organs, tissues, and body structures, as well as the growth and differentiation of cells. By the end of the first trimester, the embryo is typically referred to as a fetus, and continues to grow and mature throughout the remainder of the pregnancy.
Fingers and toes develop during the first trimester of pregnancy in a human fetus.
The embryonic period extends to the end of the eight week. After the embryonic period (8weeks), the developing human is called a fetus.
After a sperm fertilizes an egg its referred to as a zygote. Then it becomes a fetus, I believe after the first trimester.
The first trimester ends at week 13, when the developing embryo becomes a fetus.
The development of a fertilized egg starts out as an embryo though after 8 weeks it is legally considered a fetus.
The attachment of the embryo to the placenta by the umbilical cord and the placenta's contact with the uterus occurs during the first trimester of pregnancy. This is when the embryo develops into a more complex structure, and the placenta begins to form and function, facilitating nutrient and waste exchange between the mother and the developing fetus.
The definition of early pregnancy is known as the first trimester. The duration of the first trimester is 12 weeks, and includes conception, implantation, development of the embryo and development of the fetus.
The first trimester and then it's usually because the embryo/fetus is not viable but damaged by nature somehow.
During the third trimester of pregnancy, the fetal heart rate typically ranges from 110 to 160 beats per minute. This rate may vary depending on the fetus's activity level, with rates often increasing during periods of movement and decreasing when the fetus is at rest. Regular monitoring of the fetal heart rate is important for assessing the health and well-being of the fetus during this stage.
