fertilization. It starts when the female ovulates producing

an egg. This egg then travels into the fallopian tube where

it waits to be fertilized. Once sperm enter the body they

must travel up the uterus until they make their way up to

the egg. Once at the egg the sperm try to get in. They

sperm wiggle their tails until they make it in. Once it

makes it in the egg will not any other sperm in. The sperm

that made it then drops its tail. After about twenty hours

inside the egg the sperm finds the nucleus of the egg and

fuses with it. Now the egg has all the genetic material

that it needs to make a new human being. It nows begins to

move down into the uterus. The egg is now called a

blastocyst. The time that this takes is often measured

after the last menstrual period(LMP). The time is also

measured in trimesters, three month intervals.

After about thirty hours the cell divides for the first

time. It is continuously moving towards the uterus where it

will call home for the next nine months. After about two

days it has divided to having about eight cells. After four

days it is in the uterus and has to "land" somewhere
