When the embryo reaches the uterus, it is a hollow ball of about 100 cells called a?
When the embryo reaches the uterus, it is a hollow ball of about 100 cells called a blastocyst. The blastocyst is made up of an outer layer of cells that will develop into the placenta and an inner cell mass that will develop into the embryo.
What happens to the embryo between fertilization and implantation?
After fertilization, the embryo undergoes several cell divisions to form a ball of cells called a blastocyst. During this stage, the blastocyst travels through the fallopian tube to the uterus for implantation. Once in the uterus, the blastocyst attaches to the uterine lining and begins to receive nourishment from the mother's body.
About four or five days after fertilization a group of cells forms a ball-like structure. What is the name of this structure?
Blastocyst.
What follows fertilization in cells?
After fertilization, the zygote forms from the fusion of the egg and sperm. The zygote then undergoes multiple rounds of cell division through a process called cleavage, resulting in the formation of a blastocyst. The blastocyst implants into the uterus, leading to the development of the embryo.
How does a zygote divide to form an embryo?
During the process of cleavage, a zygote undergoes rapid cell divisions to form a cluster of cells called a morula. The morula then develops into a hollow ball of cells called a blastocyst, which eventually implants into the uterus and forms an embryo.

How long does it take for the ball of cells to reach the uterus?
It takes about four days.
What is the ball of dividing cells that implants into the uterus?
do you mean the egg?

What happens to the fertilised egg in the first few weeks?
It splits into two cells and these split into two each and so on until you have a ball of cells. These are assigned various tasks. The phoetus implants into the uterus wall
What is a amnion sac mean?
In the first developmental stage of the embryo, you have the ball of cells. In this ball of cells you have cavity filled with fluid called amniotic fluid. This fluid sac separates the embryo, from the outer non-embryo cells. Later on it encloses the fetus in amniotic fluid to give amniotic sac. This sac is attached to uterus from inside.
What is found inside a football ball?
A lining, then air.
Pathway of the female reproductive system?
for successful fertilusation to take place the penis must enter the vagina and ejaculate spermazoa (sperm) into the vagina. the sperm then travels into the fillopian tubes where an egg will be making its way towards the uterus after ovulation. the sperm then fertilises the egg, this process forms a zygote. as the zygote travels towards the uterus clevage begins (clevage is the dividing of the ball of cells to form a ball of cells, reffered to as the embryo). the embryo then embedds into the uterine wall lining (endometrium) where it then begins its growth and development. the endometrium provides the embryo with nutrients for growth and development. after the emrbyo has had time to develope in around 9 months the baby will be born.
Where do the first few cell division occur?
The first few cell divisions occur in the fallopian tube after fertilization. The fertilized egg undergoes several rounds of cell division to form a solid ball of cells called a morula, which then develops into a hollow ball of cells called a blastocyst as it moves towards the uterus for implantation.

To what size does the uterus grow to at 9 months?
about the size of a tennis ball
