This is page has been made to help the younger student (from K to 12) understand some of the basics of how an embryo grows.
||This movie covers the 9 months of human development. Starting after fertilization and ending with the fetus just before birth.
The movie also shows how the embryo attaches to the mother's uterus (right) and how the placenta forms.
The movie near the end shows only the fetus.

In humans, the growth of a baby inside a mother takes about 9 months.
In chickens, mice and rats this growth only takes about 3 weeks.
- Question: How long does it take for cats and dogs to develop? (Dogs)
- During this time a single cell will grow into many different cell types with different shapes and jobs to do in the body.
- A similar development process will occur in all different embryos.
- In humans, many important changes occur in the first few weeks of development and much of the following 9 months is growth.
|The table below shows the development time for a large number of different animals, ranging from the opossum at 12 days to the elephant at 660 days.
Now follow the growth and changes in the human embryo over time.
