This refers to the development and formation of an embryo. Everything that has been mentioned and discussed in this presentation is the process of embryo development!

# data[].attributes.body
This structure connects the fetus to the placenta and aids in the transfer of oxygen and nutrients.

# data[].attributes.body
Carries oxygen and nutrients from the mother to the fetus and delivers waste from the fetus to mother.

# data[].attributes.body
Created by totipotent cells, the extra embyronic structures consist of the chorion, amnion, allantois, and yolk sac.

# data[].attributes.body
These cells can create a complete organism. When given the right maternal support, they can create extraembryonic tissues and all tissues of the body.

# data[].attributes.body
The changing of a cell to a more specialized cell type. There are three different types (Pluri, Multi, & Toti) of stem cells and they differentiate each in their own way!

# data[].attributes.body
These cells develop into specialised cell types that are present in a tissue or organ.

# data[].attributes.body
Differentiation is a term that refers to how cells become specialized, on the other hand morphogenesis refers to the development of the forms of living organisims.

# data[].attributes.body
This is the process that causes cells to develop its destined shape.

When gastrulation ends, differentiation has begun. It's the process of cells developing a specific shape and performing specific functions.

After the process of gastrulation and the germ layers have developed, you are left with a gastrula. It is a multilayered and multicellular embryo.

# data[].attributes.body
The last layer formed in gastrulation, this is the outer layer. Forms the brain, nervous system, teeth, mouth etc.

# data[].attributes.body
This is the second layer created, it is in the middle of the ectoderm and endoderm- the middle layer. Forms muscle, blood, bone etc.

# data[].attributes.body
The inner layer that will soon develop into the liver, pancreas, thyroid, respiratory tract, and more. It's the first layer that must be created.

# data[].attributes.body
There are three germ layers (inner, middle, and outer) that develop as a result of gastrulation.

# data[].attributes.body
These cells can self renew by dividing and also have the capacity to develop into the three germ layers in the early stages of the embryo.

# data[].attributes.body
The process of which a blastula will form into a gastrula by undergoing more development.

# data[].attributes.body
The last of the three membranes however this does not protect the embryo, this helps with the yolk sac to produce blood cells. This will later on become the umbilical cord.

# data[].attributes.body
The yolk sac will develop at the same time as the amnion but can not be seen until five weeks of gestation. It provides nutrition and gas exchange for the embryo before the placenta can take over.

# data[].attributes.body
Another one of the three membranes that protect the embryo, the amnion grows into a fluid filled sac that insulates and protects the embryo.

# data[].attributes.body
Pregnancy tests are able to determine if a woman is pregnant or not by the level of HCG in urine!

# data[].attributes.body
This hormone maintains the corpus luteum so the corpus luteum can continue producing estrogen and progesterone to maintain the endometrium.

# data[].attributes.body
One of the three membranes that protect the embryo. It is the outermost membrane, its first job is to secrete HCG, and it later develops into placental wall.

# data[].attributes.body
After the embryo travels up the fallopian tubes, it implants in the women's endometrial lining of the uterus.

# data[].attributes.body
The blastula turns into a complete blastocyst now that it contains inner cell mass and the other "organs". Occurs during day 5-9.

# data[].attributes.body
After the morula develops into a blastula, small groups of cells form inside of the blastula. The inner cell mass will later give rise to stem cells.

This is an early stage embryo and consists of 16 cells.

# data[].attributes.body
(This is the division of cells) The zygote will now divide by mitosis producing two cells, they split again producing four- and they continue to split.

# data[].attributes.body
Once the chromosomes of the sperm and egg combine, the resulting cell is called a zygote.

# data[].attributes.body
Beginning with copulation, sperm is delivered into the female vagina and makes its way to the fallopian tubes. A sperm cell will implant itself inside the egg if it is a match.
