2. estrogen and progesterone (into blood) |
|
|
The egg travels via?
|
Ovary-->Fallopian tube-->Uterus-->Cervix-->Vagina

fertilization
|
|
|
The uterus in for egg?
|
implantation
|
|
|
fertilized egg

|
An egg is penetrated by sperm. They form a single nucleus.
|
fertilization
|
|
|
3 days. Solid ball of cells.
|
Morula
|
|
|
hollow ball. 1 week implants into the Uterus.

Blastula
|
|
|
3 germ layers. 2 weeks. Implantation is complete.
|
Gastrula

|
|
9 weeks. Growth, tissue and organ specialization.
|
Fetus
|
|
|
uterus wall closest to base
|
Decidua basalis
|
|
|
region of the uterus wall surrounding the rest of the blastocyst.

|
If pregnant what secretes HCG?
|
blastocyst
|
|
|
=inheriting traits.
|
Genetics
|
|
|
(before fertilization)- a cell (an egg) has 23
chromosomes. n |

diploid
|
|
|
2 different copies of the same chromosome (one from mom and one from dad)
