Fetal growth occurs in three main stages: the germinal stage, embryonic stage, and fetal stage. The germinal stage lasts from conception to about two weeks, where the fertilized egg implants in the uterus. The embryonic stage ranges from weeks 3 to 8, during which the major organs and structures begin to form. The fetal stage, from week 9 until birth, involves rapid growth and maturation of the fetus, as well as the development of finer details like facial features and organ functionality.
During the late stages of development, an embryo undergoes rapid growth and further organ formation. At this stage, the major organ systems are well formed, and the embryo is starting to resemble a human fetus. Specialization of tissues and organs continues as the embryo prepares for further growth and development.
The correct order of the stages in development is typically: 1) germinal stage, 2) embryonic stage, and 3) fetal stage. These stages represent the progression from fertilization of the egg to the formation and growth of the fetus in the womb.
The stages of fetal growth and development are divided into three trimesters. During the first trimester, major organs begin to form. In the second trimester, the fetus grows rapidly, becomes more active, and the organs continue to develop. The third trimester is characterized by further growth and development, as well as the maturation of the fetus's organs in preparation for birth.
fetus
During the transition from embryo to fetus stages in human prenatal development, key milestones include the formation of major organs and body systems, the development of limbs and facial features, and the growth of the brain and nervous system. This period is crucial for the overall growth and differentiation of the developing organism.
The uterus grow to make room for the fetus. A fetus that doesn't grow - no growth of the uterus.
A fetus is another name for an unborn baby, and growth is how it gets bigger.
note on stages of economic growth
An embryo is an organism in its early stages of development before birth or hatching. It is formed shortly after fertilization of an egg by sperm and goes through various stages of growth and differentiation to develop into a fetus in mammals or a young individual in other organisms.
cell, zygote, embryo then fetus!
A developing baby in the early stages is called an embryo. This stage begins at fertilization and lasts for about 8 weeks. After that, the term fetus is used to describe the developing baby.
The Uterus is like a balloon that expands and contracts. It is also elastic so that is may holster the baby while it is in the early stages of development.
